IRA0.M18 Valve Series

Description
The IRA valve combines in one compact insert cartridge the
typical function of shock relief valve and anticavitation through the
check valve. In the pressure relief function it’s a side-in
nose-exhaust valve, with very low pressure rise thanks to the smart
deflector design.
When the pressure at the high pressure inlet (1) reaches the valve
setting, the valve starts to open to tank (2).
In the free reverse flow function a very light bias spring allows for
ease of flow passage from nose to side (2 to 1).
High precision machining guarantees quick response to load
changes, limited hysteresis and reduced internal and external
leakage.

Technical Features
All external surfaces are zinc plated and corrosion-proof.
All valve parts are made of high strength steel. Both internal and
external poppets are hardened and ground to guarantee minimal
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.
1-piece design.
Metric cavity.
