HD400

Line pressure regulator

Inlet pressure max. 440 bar / operating pressures up to 400 bar

The line pressure regulator HD 400 is a single-stage pressure regulator for high pressure applications (in- and outlet).

The HD 400 is designed as a piston pressure regulator and reduces the pressure of compressed gases or liquids to a maximum outlet pressure of 400 bar.
