Pilot operated check valve (2) Pilot operated check valve (2) Overview This pilot check valve operates the pilot using remote pressure and allows for back flow as appropriate. This valve is mainly used in a press or lift to prevent load from falling due to leakage of the hydraulic circuit. Features This is of decompression type. As the main valve opens after the pilot valve opens, smooth switching without shocks can be performed under high pressure and large capacity. Type indication Pilot operated check valve Drain system No symbol = Internal drain Y = External drain Nominal dimension 52, 62, 82, 102, 125, 150 (Gasket connection type is 52, 62 and 82 only.) Connection method F = Flange connection type P = Gasket connection type Type of hydraulic oil No symbol Mineral based hydraulic oil V Phosphate ester based hydraulic oil W Fatty ester based hydraulic oil Water-glycol based hydraulic oil Cracking pressure 10 30 45 * If you use cracking pressure of 45, please contact us in advance.
