For hydraulic pressures up to 34.5 MPa {352 kgf/cm2} Working pressure Valve structure Applicable fluids Special steel (Nickel-plated) Size (Thread) Body material Working pressure Seal material Working temperature range Fluoro rubber Nitrile rubber Working temperature range Max. Tightening Torque Two-way shut-off (Non-Spill) Size (Thread) • Locking mechanism to prevent accidental disconnection ensures tight connection even under vibration or impact. • Both socket and plug have built-in automatic shut-off valves to prevent fluid spill out when disconnected. Easy to handle. Their “airless valve shut-off design” greatly reduces air admixture! Ideal for hydraulic lines with larger pressure fluctuations. Flow Direction Fluid may flow in either direction from plug or from socket side when coupled. Interchangeability Different size socket and plug cannot be connected each other. However, 350-2SP with 350-3SP or 350-10SP with 350-12SP can be connected each other. (mm2) Min. Cross-Sectional Area Model Suitability for Vacuum Not suitable for vacuum application in either connected or disconnected condition. ( mL) Admixture of Air on Connection Admixture of air may vary depending upon the usage conditions. Model Flow Rate – Pressure Loss Characteristics [Test conditions] • Fluid : Hydraulic oil • Temperature : 40˚C 5˚C • Fluid viscosity : 32 x 10-6 m2/s • Density : 0.87 x 103 kg/m3 350-4SP Body is made of special steel for durability Seal materials do not protrude into fluid path when connected (touchless packing design) for improved durability The body material is quenched to cope especially with impulses Fitted with stopper to prevent disconnection of socket and plug. (Designed to prevent accidental disconnection) Both socket and plug have built-in automatic shut-off valves Their “airless valve shut-off design” greatly reduces air admixture Flow rate in L/min Precautions for use Do not connect / disconnect Cuplas when pressure i
