The anti-mixing double seat valve is a valve with technical characteristics such as online in-situ CIP cleaning, SIP sterilization, leakage detection, double-layer sealing protection, and prevention of the risk of medium contamination. It also has a very flexible valve body combination and Functional configuration such as valve control unit, feedback device, position sensor, etc. The design of the valve is completely based on the high cleanliness requirements of the United States 3-A-85-03 design.
Many anti-mixing valves are used in valve array systems, because the valve has the technical characteristics of online in-situ CIP cleaning, sterilization, self-draining, no dead ends, no retention, etc., and has very flexible configurations such as position feedback devices and valves Automatic control systems such as control units and position sensors.
