Flow Direction
Fluid flow can be bi-directional when socket and plug are connected.

Purge function will set you free fromthe troublesome residual pressure
elimination before connection andlet you achieve efficient and frequent
hydraulic pipe line coupling.
• Both socket and plug have built-in automatic shut-off valves to prevent fluid
spill out when disconnected.
• Interchangeable with standard HSP Cupla plug or socket in the same size.

Interchangeability
Interchangeable with standard HSP Cupla plug or socket in the same size.

Note: Either socket or plug of Hyper HSP Cupla must be used on the line where theresidual pressure remains. The counterpart of Hyper HSP must be either plugor socket of standard HSP Cupla.
When connecting, the purge valve positioned at the point ofplug valve is depressed to release the residual pressure in plug.

Residual Pressure Release (or purge) Mechanism
While connecting, the purge valve indicated with a circle is being pushed and releasing the residual pressure

Purge valve

Residual pressurein the line

Socket valve

Note: Either socket or plug of Hyper HSP Cupla must be used on the line where the residual pressure remains. The counterpart of Hyper HSP must be either plug or socket of standard HSP Cupla.
Hyper HSP Cupla can be connected under the residual pressure in the line,but cannot during pressurizing. It may lead to incomplete connection, durability deterioration or possible valve fly out.

Before use, please be sure to read “Safety Guide” described at the end of this book and “Instruction Sheet” that comes with the products.
