Valve Body

Nominal Diameter	DN15-100

Seal Material	PTFE: -20°~180℃
Stem Material	304 stainless steel
Connection End	clamp, weld, thread, flange

Working Principle:

1. Spring return single acting pneumatic actuator

Compressed air enters into port A—-pistons move outwards—-pinion rotates anticlockwise—-valve is open Compressed air exhausts at port A—-springs return—-pistons move back—-pinion turns clockwise—-valve is closed

2.  Air / air double acting pneumatic actuator

Compressed air enters into port A—-pistons move outwards—-pinion rotates anticlockwise—-valve is open Compressed air enters into port B—-pistons move back—-pinion turns clockwise—valve is closed Flow Direction Diagram: We produce both T-type and L-type sanitary three way ball valves. The T-type sanitary valve can connect three pipes in order to converge or divide fluid flows. The L-type valve can only connect two pipes in a pipeline for flow direction change purposes.
