Difference Between Unidirectional And Bidirectional Knife Gate Valve

Designed for easy quick conversion between manual and pneumatic actuation. The medium flows only in one direction an arrow must be provided on the valve body to indicate the flow direction of the medium pay attention to the flow direction of the medium during installation. For unidirectional sealing butterfly valve the front side of the disc must face to the flow direction of the medium when it is closed.

The diaphragm of the sensor should only move in one direction and will produce a positive voltage or milliamp output. That is an n channel mosfet taken as an example here conducts when the gate to source voltage is above a thresh.
