Product Overview
The TRAFAG DVB22 is a precision-engineered pressure switch designed for reliable monitoring and control of hydraulic and pneumatic system pressures in demanding industrial environments. Manufactured by TRAFAG, a globally recognized specialist in high-accuracy pressure and temperature instrumentation, the DVB22 utilizes a robust diaphragm or piston sensing element coupled with a snap-action microswitch to deliver precise, repeatable switching signals at preset pressure thresholds. Unlike continuous pressure transmitters, this device provides a discrete electrical output (normally open or normally closed) when system pressure reaches the adjustable set point, making it ideal for safety interlocks, pump control, alarm activation, and sequence control within complex hydraulic power units and automation systems.
