Relief Valves RVA0.M18 Valve Series Technical Data Maximum operating pressure Maximum flow Direct acting with anti-cavitation Setting Pressure Poppet Type 350 bar 60 l/min See table below Anti-cav cracking pressure Maximum internal leakage External component treatment O-ring Temperature Range Cross Section Oil Temperature Range Pressure settings established Reseat pressure Fluids The RVA valve combines in one compact cartridge the typical function of shock relief valve and anti-cavitation Orientation Installation torque through the built-in check valve. In the relief function when the pressure at the Inlet (1) reaches the valve Zn/Fe - standard (96h) Zn/Ni (720h) -30° C to 110° C (standard sealing NBR - BUNA-N) -30° C to 110° C @5 l/min nominal 90% of cracking pressure Mineral - based or synthetics with lubricating properties 7,4 to 420 cSt 20/18/15 ISO 4406 (maximum filtration admitted) No restrictions 50-55 Nm (Hex. 22) 5-10 Nm (Hex. 10) Technical specifications for characterization setting, the valve starts to open to tank (2) and thanks to the effect of the deflector integrated into the poppet it provides a limited pressure rise. The cartridge offers Plastic tamper proof cap Wire seals tamper proof excellent response to load changes in hydraulic circuits SK.101 CTP.001 (for more details see page 428-429) Suitable design upon request 0,117 kg requiring low internal leakage as well as limited hyseresis. Innovative design on internal dampening part gua- Ordering Code rantees great stability. In the free reverse flow function a light bias spring allows for ease of flow passage from side to nose (2 to 1) by lowering the internal seat. Technical Features All external surfaces are zinc plated and corrosion-proof. All valve parts are made of high strength steel. Poppet is hardened and ground to guarantee minimal wear and extended service life; internal seat is also ground and made of hard steel providing same advantages.
