Model : 02, 03, 04, 06, 08

High pressure (20.5MPa) Twin valve Type, Stainless Body
    • Both socket and plug have automatic shut-off valves for high pressure applications.
    • Stainless steel SUS304 for excellent resistance to corrosion.
    • The design of inner seal mechanism allows working pressure of 20.5 MPa.
    • Double-sleeve lock assures tight connection against vibration and impulse.
High pressure,Twin valve type

 

  • 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.
