Pilot operated check valve (1) Sub-plate Valve type Sub-plate type Connection diameter Mass When you use a sub-plate, please place an order for the above sub-plate type. For the dimension drawing, refer to pages 6 and 7 of the appendix.

However, if back pressure is applied to port A, be sure to use the external drain type. Pst: Minimum required pilot pressure (MPa) P1: Load pressure (pressure of port B) (MPa) P2: Back pressure (pressure of port A) (MPa) A1: Pressure receiving area of poppet (cm 2 ) (Note) For minimum required pilot pressure (Pst), low pilot operated check valves for pilot pressure lower than Pst obtained from the above (pilot pressure equivalent to approximately 1/8 of load pressure) are also available (KSV/KSL type). If you need the above valve, please contact us. 1-74
