Non Drain Type Pressure Switch Modular Valve

Main text

OW-G01-**-CR-D2-3104B

No drain flow for energy-saving operation.
Can achieve highly responsive, high-accuracy switch output.
Long life for enhanced reliability
With electric trimmer, pressure and hysteresis can be freely changed within adjustment range.
Photo coupler electrically isolates switch output from internal circuit, preventing misoperation due to noise.

Machine tools and test machines

Example of application
Because there is no drain flow, energy can be saved by stopping hydraulic equipment power when clamping.

(*1) Hysteresis can be adjusted from 1% to 10% of set pressure.
