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.
- For preventing unexpected disconnection, single sleeve lock or double sleeve lock is available.
- Lotus-shape valve stands are available for severe pressure applications.
- Nickel Plated body for water-glycol is available.
- The male type is available.
- When disconnecting, both socket and plug are sealed by automatic shut off valves instantly.
- When connecting, automatic shut off valves are open and the socket is sealed by O-ring.
- Fluid can flow from both socket and plug.
- Packing material should be selected for the applicable fluid; please consult us for suitable packing material.
- When connecting to a female thread or a hose, please use a nipple.
- Different sizes are not interchangeable.
- Do not connect or disconnect couplings under pressure.
- Don't apply pressure on a socket or a plug when disconnecting. This may cause the valve blown out.
- Don't hit the top of valve with hammer or other tools. This may cause leakage or malfunction.
- Don't use for water-glycol fluid, which damages to the plating and O-ring.
- When mounting on the male thread, excessive tightening may cause the crack of the coupling.
- Scraps of the seal tape and dust causes fluid leakage. Be careful not to stick them on the couplings.
- Putting dust covers on a socket and a plug is recommendable, when they are disconnected.
