Two-way Shutoff Quick Release Couplings
Two-way Shutoff Quick Couplings Plug is used with socket in equipment operation or maintenance of hydraulic systems to avoid fluid loss and leakage during repeated piping connection and disconnection. It is suitable for agriculture, hydraulic tools, construction, fluid conveying, transportation, chemical engineering, oil and gas, food general industry.
Two-way shutoff quick couplings present closure upon disconnection. When socket and plug are connected, two ends remain open to enable fluid and hydraulic oil to go through. The design of auto aligned valve provides better sealing.
When the plug and socket are disconnected, the design of the poppet valve enables the auto re-set to its original position before connection and enhances the safety sealing of plug or socket.
Quick Couplings include one-way shutoff, two-way shutoff and two-way shutoff (grease type), one touch quick coupling, straight through type, and camlock type.
◎ Auto aligned poppet valve provides a reliable seal.
◎ Leak tested.
◎ Withstanding high pressure seal.
