Automatic shut-off (Open/Close) valve ensures operation safety. One touch connection operation. Automatic shut-off valves are incorporated in both socket and plug (Built-in design concept). The design construction prevents fluid leakage on disconnection and allows minimum pressure losses Specifications   Body Material Special Steel (Chromium Molybdenum Steel) Zinc plated Size 1/4”, 3/8”, 1/2", 3/4”, 1” Working Pressure MPa (Kgf/cm²) 34.3 (350) Pressure Resistance MPa (Kgf/cm²) 51.5 (525) Packing Material Material Symbol Working Temperature Remarks Nitrite butadiene rubber No mark -20°C ~ +80°C Std.
