HP350

Line pressure regulator

single stage for high flow and high outlet pressure (up to 50 bar) – with a balanced poppet

The line pressure regulator HP 350 is a single stage pressure regulator with a high flow rate and is designed for pressure reduction of high purity gases.

The HP 350 reduces the pressure of compressed gases or fluids to a maximum outlet pressure of 50 bar.

It functions according to the principle guiding the equilibrium of forces between the set spring force and the outlet pressure.

The line pressure regulator HP 350 is equipped with a balanced poppet and by so doing ensures constancy in operating pressure during the entire gas withdrawal process, and occurring decrease in inlet pressure.
