SQV0.G38 Valve Series

GAS Cartridge - 420 bar
Direct acting - Poppet Type

More details

Description
Direct acting in-line sequence valve with steel housing.
The SQV provides in one easy-to-install very compact in line valve
the typical function of shock relief valve.    
When the pressure at the high pressure inlet (1) reaches the valve
setting, the valve starts to open to tank (2).
The flow in the opposite direction is blocked.
Thanks to the smart deflector design, the pressure rise is very low.
High precision machining guarantees quick response to load chang-
es, limited hysteresis and reduced leakage.

Technical Features
All external surfaces are zinc plated and corrosion-proof.
All valve parts are made of high strength steel.
Highly stressed parts are hardened and ground to guarantee mini-
mal wear and to extend service life.
Pressure setting is pre-adjusted by the factory and cannot be
changed.
Optional spring ranges to 420 bar (6000 psi).
Back pressure on the tank port (port 2) is directly additive to the
valve setting at a 1:1 ratio.
GAS ports.
