HY Type
- High pressure [20.5Mpa],Twin valveType
- HY type assures 1,000,000 cycle's impulse test.
- Surface treatment is trivalent chromate; it is obedient to RoHS regulation.

- Fluid can flow from both socket and plug.
- Automatic shut off valves of socket and plug open and seal by O-ring with Backup-ring.
*Putting dust covers on socket and plug under disconnection is recommendable.
- 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.
