Valves on the rack
15 Jan 2000
Fisher Controls International has introduced the Posi-Seal Package (PSP) high-performance rotary control valve, which combines the high performance of the Posi-Seal A41 butterfly valve with the operating power of the new Posi-Seal 1035 rack-and-pinion actuator.
Operating advantages of the PSP high-performance butterfly valve include low torque requirements that allow use of compact and economical actuator sizes, pressure-assisted, bi-directional sealing for exceptional shutoff capabilities, and optional ENVIRO-SEAL packing to meet stringent emission requirements.
The PSP is available in 3in to 12in sizes with an ANSI Class 150 rating, PTFE disc seal, and a choice of valve body materials.
