Conval: Fire-Safe Camseal Ball Valves

Conval eNews image 5.11.16NEW FIRE-SAFE CAMSEAL BALL VALVES FROM CONVAL

Camseal zero-leakage forged ball valves manufactured by Conval are now qualified for fire-safe service in ½” through 4” sizes, in both API 607 and 6FA; for all pressure classes 2500 and lower for 607 and 6FA; for low-alloy steel body materials such as A105 and F22, and austenitic body materials such as 316 stainless steel.

The new fire-safe Camseal ball valves are ideal for refining and chemical plants where fire safety is a major concern. The top-entry, cartridge-style ball valves are easy to inspect, maintain and repair. In-line renewability is accomplished within 30-minutes in the event of process application abuse. The cartridge is easily removed for on-site parts replacement, reassembly and reinstallation. No welding is required, which is especially important for valves made of F91 Stainless Steel and specialty metals. F91 is extremely sensitive to hardness and heat, making welding a sensitive operation.

ValvTechnologies: NexTech Pulsejet Valve with EcoPack

ValvTechnologies NexTech pulsejet valve with EcoPackValvTechnologies, Inc. introduced a fast-acting, high-cycle NexTech® pulsejet valve with EcoPack™ stem packing solution for the reduction of fugitive emissions.

Pulsejet valves are designed to send a pulse of gas through a pipeline system. A trunnion-mounted ball valve, ValvTechnologies NexTech® pulsejet valve is capable of 90° or 180° rotation in speeds as low as 0.5 seconds or faster: this fast actuation speed is what creates the gas “pulse” through the pipeline system. Pulsejet systems can be used to clean system filters, spray chemicals in an injection type system, or pulse debris/media through a pipeline to prevent clogging.

These systems cycle many thousands of times per day. Conventional packing systems cannot handle the abuse of the fast cycle speed, combined with the high cycle count. ValvTechnologies’ EcoPack™ solution was designed to address and overcome this challenge.

Pentair: Vanessa Triple Offset Valves Series 30-RS

Pentair Vanessa Series 30 RSPentair Valves & Controls announces the expansion of its Vanessa Triple Offset Valves (TOVs) product line with the launch of the Series 30-RS. The new manual triple offset valve is designed to address the need for zero leakage isolation in non-critical applications in the oil and gas and process industries.

The Vanessa 30-RS is specially designed for applications which require non-critical fluids isolation in lower pressure or temperature. Its safer bolted-on seat allows for true positive isolation when pressure is applied from the shaft side, thus minimizing the risk of dangerous mechanical failure compared to other bolted-seat designs. The Vanessa Series 30-RS handles temperatures up to 350°C and pressures up to ASME class 300, and is available in A216 WCB or A351 CF8M Double Flanged body.

Emerson Process Management: Metal-Seated Ball Valves

Emerson Process Management has introduced the Fisher Z500 line of metal-seated ball valves to its severe service portfolio. Fisher Z500 metal-seated valves are engineered to withstand higher temperatures, pressures, and more erosive conditions than a standard on/off ball valve, providing increased reliability and protection of critical assets in demanding applications. A bi-directional sealing design offers a unique solution to process back pressure and shutoff requirements in both flow directions, safeguarding control valves and other equipment in the line.

Emerson Process Management: Fisher 8590 Butterfly Valve

Emerson Process Management introduces the Fisher 8590 high-performance butterfly valve that brings a selection of disk seals, actuator designs and material combinations to meeting plant-wide throttling and on-off requirements.

Utilizing a lugged body design across the CL600 size range of NPS3 – NPS24, the 8590 can incorporate a splined shaft that accepts either a spring-and-diaphragm or pneumatic piston actuator. It is also available with either a square or keyed shaft that combines with handlevers, handwheels or pneumatic piston actuators.

The pressure-assisted design of the 8590 disk seals provides tight shutoff and permits the use of smaller, less expensive actuators in meeting full ASME B16.34 shutoff capabilities.

The 8590 offers true bidirectional shutoff, which means that torque necessary to open and close the valve remains constant regardless of the differential pressure across the disk. Slam-shut conditions are not created as the disk nears its seat, which extends seal life and avoids actuator and piping damage.
