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.

Caution:

• 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.
