description

Pilot and direct operated pressure relief valves NG6. Flange and sandwich design

according to ISO 4401-03 with 4 connections. Proportional pressure relief cartridges M22x1.5 according to ISO 7789 are installed. The steel bodies are for flange and sandwich construction

phosphated.

function

When the set operating pressure is reached, the piston opens and connects the secured line to the return to the tank

T. For flange and sandwich versions

with pressure limitation in P is standard

a connecting thread G1 / 4 "(closed)

intended. It enables connection

a manometer.
