A unique “O”-Ring seal prevents leakage around the shaft. Available from 1” to 6” pipe sizes. The valve crank rotates through an 80° arc. Disc position is indicated by a slot on the disc shaft relative to the nameplate scale. The mounting bracket is pre-drilled for a Pyronics PA-6 pneumatic actuator (see Bulletin 1701).

The TBV-CPAP includes the butterfly valve, actuator mounting bracket, valve crank arm, and an adjustable linkage.
