The S Type Check Valve is designed to allow hydraulic oil flow in one direction while blocking flow in the opposite direction. This one-way flow characteristic is essential in hydraulic systems where controlled flow is needed to prevent backflow. The valve features a pipe connection (type “G”) for easy installation in various hydraulic systems.
