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.

Garlock: Butterfly Valve Line

The Garlock family of companies has reintroduced the Garlock butterfly valve line, a group of flow control products specifically built to handle a wide range of extreme, sterile and chemical transportation and storage conditions, with three new offerings within the Garlock butterfly valve line: the STERILE-SEAL, the SAFETY-SEAL and the MOBILE-SEAL.

GAR-SEAL butterfly valves provide critical shut-off duties and manage the flow of acidic, caustic, abrasive or toxic media that could severely damage or be too challenging for other valve systems. STERILE-SEAL butterfly valves are designed for applications where completely sterility is required, such as in the pharmaceutical and food & beverage production industries. The STERILE-SEAL is only available with a PTFE liner, and offers a unique external sterilization option: ‘dead’ areas of the valve, along with the disc, body liner and inner seals, can be thoroughly sterilized with steam and allow no possibility of contact with internal media. The SAFETY-SEAL is specifically designed to negate charge build up and dissipate static. Finally, the MOBILE-SEAL butterfly valve is intended for tanker vehicles, railway wagons, fluid storage silos and other containers where dangerous media are contained.

The Garlock butterfly valve line is offered with a wide range of accessories, including standard handles, locking handles, gear operators and air actuators.
