A-Series Flap Gate Valves
The A-Series Cast Double Flapgate Airlock Valves are designed for medium-pressure applications and standard temperatures to 650°F. Their cast iron housing, White Iron/Ni-Hard seats and flaps make them an economical alternative to rotary valves.
These valves are designed for dust collector, precipitator and cyclone applications where maximum pressure differentials are 83″ WC (3 psi). They can also replace traditional rotary airlocks experiencing premature wear. The seats and gates can be re-ground extending the working life of the valve.
A low profile enables the MPSA model to directly fit in place of most rotary valves. MPFTA matches the “industry standard” flange pattern and height. The MPSA and MPFTA models are available with your choice of pneumatic, electro-mechanical or gravity/counterweight actuation.
