SP Type

Medium pressure, Twin valve Type

Both socket and plug have automatic shut-off valves for medium pressure applications.
Various packing materials enable a wide variety of applications.
SUS 316 is available.

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.
*Different sizes are not interchangeable.
*To specify the material of packing, please advise us the name of fluid.
*When connecting to female thread or hose, please use a nipple.

Caution: Do not connect or disconnect couplings under pressure.; Do not apply pressure on socket or plug under disconnected. This may cause the valve to be blown out.; Do not hit top of valves with hammer or other tools.This may cause leakage or malfunction.
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.
