Profile: Posi-flate offers a variety of solutions for Butterfly Valve needs. We produce a complete line of butterfly valves for handling a wide variety of dry bulk granular solids, liquids and gases. Our standard finishes include urethane coating, nylon powder coating, epoxy coating and highly polished stainless steel discs.

Inflatable Seated Butterfly Valves
Our 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 very 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.

Stainless Steel Butterfly Valves
Our inflatable seated butterfly valve from Posi-flate features a fully machined 316L stainless steel housing. The single piece disc and shaft is available in a number of materials including 316L stainless steel. This valve is ideal for powders, granules, slurries and liquids and is available in sizes 50mm to 750mm. Typical applications include loading and unloading of process material, sterile air control, and outlet valves for storage containers or hoppers.

Control Assembly
Our 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. The central manifold provides direct mounting to the actuator. The manifold contains a regulator which controls seat pressure and a gauge which reflects the actual seat pressure. The final component is the seat sensor cartridge, which monitors the position of the actuator.
