Working principle
This mix-proof valve is normally closed (NC) state in common. It is assemblied with two small pneumatic valves. Under normal conditions, it is normally open (NO). It only needs to supply compressed air to the pneumatic head to close the two small valves synchronously. The main valve core is equipped with two independent seals, and a leak detection cleaning chamber is formed between the two seals, and the leaked product can flow out from the small valve outlets on both sides, and the seal is replaced in time. During the CIP cleaning, the fluid flows to the square core of the spool, which can completely clean the main spool (the main spool has a taper), and can also make the external CIP valve insensitive to the water hammer effect. It is mainly used for fluid cut-off in pipeline systems and is used in pipeline systems.
