Nachi Non Drain Type Pressure Switch Modular Valve

Made in: Japan
Manufacturer: NACHI
Model: Non Drain Type

Features

  • 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.

Application

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.

Nachi Non Drain Type Pressure Switch Modular Valve
(*1) Hysteresis can be adjusted from 1% to 10% of set pressure.
