SH Type
- 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 20.6 Mpa.


- 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.
*Putting dust covers on socket and plug under disconnection is recommendable.
*Fluid can flow from both socket and plug.
*When mounting in a female thread or hose, please use a nipple.
- Caution
- Do not connect or disconnect couplings under pressure as well as with residual pressure.
- Do not apply pressure on socket or plug under disconnected. This may cause the valve to be blown out.
- For hydraulic fluid use, ,keep its flow rate less than 8m/s.
- When mounting on male thread, excessive tightening may cuase the crack of coupling.
- Scraps of the seal tape and dust causes fluid leakage. Be careful not to stick them to the couplings.
- Scraps of the seal tape and dust causes fluid leakage. Be careful not to stick them to the couplings.
