Rexroth Z2S6 sandwich plate pilot operated check control valve is using poppet spool with good sealing performance. The valve can have one or two actuator ports for leak free blocking to keep the pressure in the pipeline when the sealed oil circuit needed in the hydraulic system. There are two kinds of leakage control of the hydraulic pilot operated check valve: internal drain and external drain. The internal drain is available within the reverse port of the flow without back pressure, otherwise the external leakage, in order to reduce the pilot oil pressure.

Please check the following troubleshooting before run the sandwich plate hydraulic pilot operated check valve  
1. When the directional control valves cannot shift or slow movement, generally due to poor lubrication, spring is stuck or damaged, oil or impurities stuck sliding part causes. In this regard, it should first check the oil flow is working properly; viscosity of lubricating oil is appropriate. If necessary, replace the hydraulic oil, cleaning the sliding part of the valve , or replace the spring .
2. The seat and piston will lead to an abrasion after long time operation, there is a little oil leakage from the service port, please check the seal ring and the seal surface of the seat and poppet evaluating the possibility of changing the parts or the valve.
