Home > Products > Couplings > YSP Medium and Low Pressure Applications (Two-way Shut-off Valve) Automatic Shut-Off Valves at Both Socket and Plug! Excellent durability at any environment. Rigid construction design allows smooth working even at vibrations without any leakages. Automatic shut-off (open/close) valve mechanisms are used in both socket and plug. Insertion of plug automatically opens the valve to allow fluid flow. Several types of body and packing materials are available to suit a variety of fluids and application requirements. Designed to SAE standards conformity. Excellent durability and operation life. Tested for 100,000 Valve Open/ Close operations.
