Less friction, low torque, less wear, longer life.
Posi-flate®'s unique butterfly valve design uses air pressure to expand the seat against the disc, providing even pressure distribution for a bubble-tight seal, every time. Because the seat makes only casual contact with the disc during valve opening and closing, there is minimal disc impingement. This is in contrast to conventional butterfly valves where disc impingement leads to shaving of the seat, decreasing the overall performance and valve life.
Substantially less torque is required to open and close the Posi-flate® butterfly valve, thus a smaller actuator can be used resulting in lower overall valve cost.
In actual comparison tests and documented field applications, the Posi-flate® butterfly valve outperformed all other valves. In fact, a Posi-flate® valve life of one to three million cycles, even in extremely abrasive applications, is not uncommon. For dry solids, gases and slurry applications, the Posi-flate® inflatable seated butterfly valve is unsurpassed.
The Double Dump Valve Assembly by Posi-flate® is a low cost and low maintenance alternative to the traditional rotary airlock feeder and provides a positive seal that that can accommodate either full vacuum or pressure up to 100 PSIG. The air-operated seat inflates to provide a long-lasting high integrity seal and easily handles high cycling of dry granular or fine powdered materials.
Heavy-Duty Rack and Pinion Extended Life
Up to 15 Million Cycles
The TRAK-LOK® 649 Series limit switch and position monitor provides point-to-point switch signaling combined with continuous on-site visual monitoring in one compact UL listed enclosure. It is ideally suited for use with the TORK-MATE® Series 890 pneumatic actuator for operation of Posi-flate® inflatable seated butterfly valves.
The TRAK-LOK® 649 Series limit switch utilizes high grade components throughout for dependable and economical valve monitoring in an industrial process environment, providing improved information flow, safety management and productivity.
NEMA Compliant
The Posi-flate® control assembly meets NEMA 4, 4X, 7, 9 and 12 requirements. It consists of three major components - the solenoid valve, the central manifold and the seat sensor cartridge.
The solenoid is available in numerous electrical voltages and can be configured so that the butterfly valve is normally open or normally closed. Clean, dry air at 80 to 115 PSIG is supplied to the solenoid air supply port.
Accurate Valve Positioning
The Posi-flate®Pneumatic Positioner provides accurate valve positioning with advanced features. A current-to-pressure transducer for 4-20 mA signal inputs proportionally positions the disc.
The Posi-flate® Series 476 Inflatable Seated Knife Gate is all full-bore" and available in both mild steel and stainless steel construction. The knife gate comes complete with air operator and solenoid valve.
All standard valves are pressure rated to 150 psig and temperature rated to 200 degrees Fahrenheit using standard seals. Optional seals are available.
The VMAX™ Linear Vibrator operates with low noise levels and high force outputs and accommodates the most demanding of applications. Special end mounts, dual ports and a totally enclosed housing make it one of the most unique linear vibrators on the market. With a state-of-the-art piston design, the VMAX™ linear vibrator does not require a spring to start and is centrifugally balanced, which prolongs the life and increases the force output over conventional models. The VMAX™ vibrator comes in a variety of sizes to suit almost every application, big and small.
The Posi-flate® Series 473 Regulator is designed for exceptionally long life as a remote pilot operated air pressure regulator.
