LH1

Line Pressure Regulator

The line pressure regulator LH1 is characterised by an accurate regulation and a large throughput.

The spring-loaded pressure regulator works according to the principle of the force equilibrium between the adjusted spring force and the outlet pressure.

It can be equipped optionally with an inlet and an outlet gauge.

Design

A large independence from fluctuation of the inlet pressure is reached with a balanced poppet.

The use of high-grade steel in connection with elastomer made of viton permits the application of this pressure regulator with aggressive media.
