Relief Valves - Insert Type
IRV0.M16
METRIC Insert - 350 bar
Direct acting - Poppet type
Description
The IRV valve provides in one compact insert cartridge the typical function of shock relief valve, side-in nose-exhaust. When the pressure at the high pressure inlet (2) reaches the valve setting, the valve starts to open to tank (1). The pressure rise is very low thanks to the smart deflector design. Flow passage in the opposite direction (1 to 2) is blocked. High precision machining guarantees quick response to load changes, limited hysteresis and reduced internal leakage.
Technical Features
All external surfaces are zinc plated and corrosion-proof. All valve parts are made of high strength steel. Both internal poppet and the valve seat are hardened and fine finished 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 350 bar (5000 psi). 1-piece design. Metric cavity.
