Sanhua Pressure Controller

Pressure Controller

DKQ/GKQ/SKQ series pressure controllers are typically used in refrigeration and airconditioning systems to protect the systems from extremely low suction pressure or extremely high discharge pressure.

The pressure switches are also used to start or stop the refrigeration compressors and air-cooled condenser fans, to regulate oil differential pressure and other systems which require pressure and differential pressure control.
