operational principle

This valve is normally in a normally closed (NC) state and is equipped with two small pneumatic valves. Normally, it is in a normally open (NO) state and only needs to supply compressed air to the pneumatic head to synchronously close the two small valves. The main valve core is equipped with two independent seals, forming a leak detection and cleaning chamber between the two seals. Leaking products can flow out from the small valve outlets on both sides and the seals can be replaced in a timely manner. When performing CIP cleaning, the fluid flow is facing the square core of the valve core, which can comprehensively clean the main valve core (with a taper on the main valve core) and make the supplied CIP valve insensitive to water hammer effects. Mainly used for fluid cut-off in pipeline systems, applied in pipeline systems.
