B81HP Sanitary solenoid valve

Application

B81MS and B81HP sanitary solenoid valves are widely used in places where there is a need for hygiene in the pharmaceutical, food, environmental, and water treatment industries.

Features

Exquisite appearance, sanitary standard; German technology, stable performance; authoritative coils, not easy to burn; in the pipeline system with high requirements for hygiene.

Principle

It is a combination of direct motion and pilot type. When there is no pressure difference between the inlet and the outlet, after energization, the electromagnetic force directly lifts the pilot small valve and the main valve closing member upward, and the valve opens. When the inlet and the outlet reach a pneumatic differential pressure, after the energization, the electromagnetic force leads the small valve, the pressure of the lower chamber of the main valve rises, and the pressure of the upper chamber drops, so that the main valve is pushed upward by the pressure difference; when the power is off, the pilot valve uses the spring. The force or medium pressure pushes the closure and moves down to close the valve.
