Many pneumatic valve actuators installed in remote locations are operated using natural gas, but this technology releases atmospheric emissions every time the valve is actuated. Electric actuators address this issue by eliminating control-related emissions, but existing solutions have limitations, each of which is addressed by the 200R actuator.

• Easy installation & calibration: The 200R calibrates itself when a user simply clicks one button using the easy-Drive Configurator Software, provided free of charge with the actuator.
• Low energy usage: Operates on 11 to 30 VDC power and consumes less than 0.4 watts when in the holding position mode, making it suitable for use in applications without available utility power.
• Low-temperature operation: Operates in temperatures as low as -40°F (-40°C), eliminating the need for a space heater in all but the most extreme temperature applications.
• Loss of power positioning: In the case of loss of power, the actuator can be driven to the user-defined position using its optional RPU-100 reserve power unit.
• Remote monitoring & configuration: Real-time monitoring of position, movements, cycles, travel time to position and power loss available via a Modbus RTU serial interface.

The 200R is an extension of the easy-Drive actuator portfolio, which also includes actuator options for both globe and rotary valves. To learn more, please visit the company's website.

The Fisher 63EGLP addresses this and other issues because it is the only pilot-operated relief valve on the market designed specifically for this type of service. Operation is implemented with a dual pilot array, providing redundancy, and allowing for removal of one pilot for testing while the other is operational.

Because this is a critical safety-related application, reliable operation over a long lifecycle is needed. This requirement is met by the 2-inch PRV because it is similar in design to the Fisher 63EGLP 4-inch CL300 model, which has been proven in use over the past 10 years.

Pneumatic controllers have served industry well for decades to regulate control valve actions, but they have many limitations. Closed loop control is sluggish and not precise, with significant deviations from setpoint common, and degraded performance over time as their mechanical components wear out. This wear and tear negatively impacts reliability, with excessive maintenance required. All interactions with pneumatic controllers must be performed locally at the control valve, creating safety issues by exposing personnel to often hazardous plant environments.

The DPC2K addresses these and other issues, and it can be retrofitted as a direct replacement for the pneumatic controllers installed on most valves, regardless of manufacturer. Closed loop control is greatly improved with configurable loop types, over 150 units of supported measure, 20 times-per-second (50 milliseconds) scan and update rates, configurable dead band, anti-reset windup, dynamic reset limiting and other features. These features work together to keep the process variable — typically pressure, flow, level or temperature — close to setpoint, along with greatly improved recovery from saturated conditions.

The DPC2K is designed to maintain its high level of performance for years with no required maintenance, and when maintenance is required, it is easily performed using modular replacement components. Another important advantage of this upgrade is the ability to easily interact with the DPC2K locally or remotely. Local interactions are performed via its menu-driven LCD and six-button user interface, with four buttons used for navigation and two for operator input.

The DPC2K has inputs, outputs and intelligence to perform local closed-loop digital control using the proportional–integral–derivative (PID) controller. It can accept a 4-20mA input from a two-wire or four-wire instrument, typically the process variable (PV). For pressure control applications, an optional pressure sensor can be used to provide the PV.

Fisher LoopConnect software provides the most comprehensive remote access, including configuration and monitoring, networked or direct Ethernet connection, and alerts for troubleshooting. Options include integral, sealed gauge pressure sensor with 0-30, 0-100, 0-300, 0-600 or 0-1500 psi range; and pneumatic output with low bleed of less than 3.0 standard cubic feet per hour.

Because the DPC2K is configurable, the same base model can be used in a variety of applications, including but not limited to pressure, flow, level, temperature, percentage, volume and rate control. The DPC2K is rated for use in Class 1 Division 1 or Zone 1 hazardous areas, and it has an operating temperature range of -40 to 80 degrees Celsius (-40 to 176° F). Inputs of 9-28 volts direct current are accommodated, with a typical power draw of only 1 watt.

With valves accounting for up to 70% of fugitive emissions (FE) from plants and refineries, tackling leakage is among the biggest obstacles to U.S. industry achieving net zero by 2050.

IMI CCI has developed the EEEasy-Seal emission packing solution, which provides up to ISO Class AM FE leakage protection and is third-party certified to ISO 15848-1, the industrial standard for FE control valve testing. In contrast to conventional packing set designs with external springs, the EEEasy-Seal is live loaded via an internal spring utilizing the internal hydraulic pressure to optimally energize the seal, resulting in a closed, low-maintenance design.

The IMI CCI EEEasy-Seal can be installed in a compact, fireproof packing box without external live loading or requiring continuous maintenance, helping tackle FE leakage concerns. IMI-Critical.com

AUMA Actuators Get VA2 Certification

Gas Industry Standard (GIS)/VA2 specifies the requirements for electric-powered actuators for use with two position (open/closed) quarter turn valves manufactured to the requirements of GIS/V6. AUMA's range of SAEX and SAREX actuators, with the combination of explosion proof controls, are GIS/VA2 compliant.

Explosion-proof devices must be used in plants where potentially combustible atmospheres can occur. AUMA’s comprehensive range of VA2 approved devices is designed so they will not act as an ignition source, manufactured to exacting specifications to prevent the occurrence of ignition sparks or hot surfaces. The actuators are also qualified to receive high Safety Integrity Level (SIL) capability.

Actuators manufactured to VA2 are suitable for use in areas in which an explosive gas atmosphere is likely to occur in normal operation; with atmospheres containing propane, or gases and vapors of equivalent that are equally hazardous.
AUMA’s actuators for hazardous locations are designed to meet the exacting requirements of the global oil and gas industry, combining the highest level of explosion protection, robust design, ease of operation and the latest trends in digitalization.

Control valve noise is often problematic in industrial applications. It is created by high pressure drops across a valve, which generate high velocities as the fluid moves through the narrowed passages in the valve body. This aerodynamic noise has a strong dependence on the gas velocity, so high flow and high pressure drop applications tend to reach high sound levels very quickly. This type of noise can damage hearing, and over time it can destroy tubing, sensitive equipment, nearby piping connections and valve components.

Rotary valves are typically less expensive than globe valves, but they are inherently prone to higher noise levels due to their trim configuration. It is difficult to incorporate a large amount of noise reduction into the trim because of the limited available space and other factors, so rotary valves are not usually employed in high noise applications.

Photo Credit: Emerson

The new rotary style Fisher Whisper Trim Technology addresses this issue, with additive manufacturing used to provide up to 20 A-weighted decibels (dBA) of sound level reduction, a 10 dBA improvement compared to traditionally manufactured solutions. These noise reduction levels are achieved while largely maintaining the high flow capacities common with rotary valves, and this solution saves significant costs as compared to globe valve alternatives.

A wide selection of low noise trims is currently available in globe valves, each using a progressively more complicated trim configuration to produce higher levels of noise reduction. Usually, the more complex the trim style, the higher the noise reduction and cost, and the lower the flow capacity. If high flow capacities are required, a much larger valve body has been necessary when using traditional low noise trim designs.

The new globe-style Fisher Whisper Trim Technology addresses this issue by using additive manufacturing to create trim designs with increased flow capacity. Globe valves using this technology have a 20% increased flow capacity as compared to traditional trim designs, while still offering up to 30 dBA noise reduction. This enables the use of smaller valves where larger sizes were previously required, saving space and cost.

Each of these solutions provides significant noise reduction without the drawbacks of traditional designs, giving end users more choices to solve issues related to valve installations where noise is problematic.

The new valve controller technology improves the performance, reliability and uptime of both on-off and control valves — and, by extension, an entire process plant or facility — in a wide variety of process industry applications providing the information required to create streamlined work processes.

Digital valve controllers are available as accessories for control and on-off valves to provide local analysis of valve data, digital communications with host systems and other features. These features improve uptime by alerting personnel to developing problems, reduce maintenance costs by providing the actionable information required for proactive rather than reactive maintenance, and cut troubleshooting time in the event of an issue by providing recommended corrective actions. For example, a control valve may be reacting slowly to commands requiring it to move, which is often an early sign of impending issues. The DVC7K will recognize this type of condition, alert personnel and provide recommendations for fixing the problem.

The DVC7K interprets data to create an optimized path to action by combining patented technology, experience-based algorithms and continuous real-time analytics with flexible connectivity and easy integration. It uses powerful, real-time and onboard edge computing to analyze issues and create actionable information, providing awareness of valve health by analyzing data locally via its onboard diagnostics. If analysis reveals a problem, an alert is created, which can be viewed locally or remotely, providing the information required to create streamlined work processes that save time and money. All alerts include recommended actions to fix the problem, a new feature for digital valve controllers and unique to the industry.

Previously, digital valve controller data had to go to a host system to be processed and prepared for viewing. However, with the intelligence of this system, data is now accessible without requiring access to the host software. All information can be viewed at the DVC7K’s local user interface, nearby via Emerson Secure Bluetooth wireless technology, or remotely after it is transmitted via a wired digital network to a host, such as a distributed control or asset management system.

The local user interface provides indication of valve health at a glance via LEDs, and users can drill down from the interface home screen to find more information. Emerson Secure Bluetooth enables access to one or more digital valve controllers at distances up to 30 feet from any device capable of supporting Bluetooth, such as a smartphone or tablet. Whether the information is viewed locally, nearby or remotely, plant personnel can use it to drive awareness of valve health.

With increased remote connectivity and Advice at the Device local diagnostics, flexibility increases providing the information needed for fast decisions and quick action to address arising issues. The DVC7K can be specified for all new valve purchases, and it can be retrofitted to most existing valve installations, in either case quickly and easily commissioned via the local user interface. With over three million Fieldvue units sold and 10 billion hours plus of field operation, long-term reliability and performance are proven in use, a key requirement as Fisher and other Emerson valves are often used in critical process industry applications.
