Specifications Special steel (Nickel-plated) Body material Valve structure Applicable fluids Torque Two-way shut-off Working temperature range Seal material Nitrile rubber Seal material Working temperature range Residual pressure allowance in plug Connects hydraulic piping even with residual pressure up to 20.6MPa {210kgf/cm2} Working pressure Flow Direction Can be connected even with residual pressure in plug side hydraulic line. This Cupla is best for frequent connection of pressurized hydraulic lines. • Super HSP Cupla socket can be connected easily with small power to standard HSP Cupla plug even with residual pressure on the plug side of the hydraulic line. • For impact resistance, especially repeated impulses, special quenched steel is used for the body. This ensures original performance over a long period. • The design reduces pressure loss, and so particularly suitable for hydraulic applications where enough fluid flow is essential. Both socket and plug have built-in automatic shut-off valves to prevent fluid spill out on disconnection. Fluid may flow in either direction from plug or from socket side when coupled. Note: When the socket is connected to the plug with residual pressure, pass fluid for at least 30 seconds from socket side at a pressure of minimum 1MPa plus the residual pressure in order to fix and keep the socket valve open. Interchangeability Supre HSP socket should be used with existing HSP Cupla plug. Min.

Super HSP Cupla Models and Dimensions WAF : WAF stands for width across flat. HS type (Female thread) How to Use Super HSP Cupla Valve is opened with appropriate pressure (residual pressure plus 1.0MPa ({10kgf/cm2} or more) from the socket side and then locked. Connected to plug with residual pressure. In condition , if fluid with pressure (residual pressure plus 1.0MPa) flows, the plug valve is pushed in by socket valve under that pressure and open to flow the fluid. At this time the balls indicated by an asterisk on the sketch completely lock the socket valve. When the socket valve is locked...
