HP Type
- High Pressure (20.5MPa) , Twin valve Type
-
- Chrome-molybdenum steel body withstands vibration and pressure impulse.
- Important parts are hardened for high durability.
- Lotus-shape valve stands are available for severe pressure applications.
- Nickel Plated body for water-glycol is available.

- When disconnecting
both socket and plug are sealed by automatic shut off valves instantly. - When connecting
automatic shut off valves of socket and plug open and seal by O-ring with Backup-ring. - CHP04 and CHP06 are interchangeable as well as CHP10 and CHP12.
- The rest of combinations for different sizes are not interchangeable.
*Putting dust covers on socket and plug under disconnection is recommendable.
*Fluid can flow from both socket and plug.
- Caution
- Do not connect or disconnect couplings under pressure as well as under residual pressure.
- Do not apply pressure on socket or plug under disconnected. This may cause valve to be blown out.
- Do not hit top of valves with hammer or other tools.This may cause leakage or malfunction.
- Do not use for water-glycol fluid which damages to coupling's plating.
For hydraulic fluid use , keep its flow rate less than 8m/s.
