working principle

This type of valve has two independent spool seals. During normal operation, a leak chamber is formed between the two seals. In the event of an accident or product leak that may occur occasionally, the product will flow into the leak cavity and be discharged from the discharge port without causing contamination or mixing of the product; when the valve is open, the leak cavity It is closed, and there is no product spillage during normal valve operation. Therefore, the delivered product can flow from one pipeline to the other. This type of valve can be CIP cleaned.
