SPE Type (PAT.P) Interchangeable with conventional CSP types
- New ! Large & Smooth Flow Type
- Evolution for Efficiency !
- Invention of New mechanism !
We developed to minimize pressure loss, by analizing the flow condition in the inner mechanism.
*Studing the block of flow in the each structures, we found the solutions to reduce the loss.
- [ The example of pressire loss ]

We designed the new inner parts to make ideal flow condition.
*Finally succeeded in large , smooth flow and reduction of pressure loss.
*More flow by 200% than NAC CSP06.

Change of seal improved the packing function.
*From Press insertion sealing to Shaft sealing.

- 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 and conditions.

- When disconnecting
both socket and plug are sealed by automatic shut off valves instantly. - When connecting
automatic shut off valves of socket and plug opens and seals by O-ring with Backup-ring.
*Putting dust covers on socket and plug under disconnection is recommendable.
*Different sizes are not interchangeable.
- 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 a male thread, excessive tightening may cuase the crack coupling.
- Scraps of the seal tape and dust causes fluid leakage. Be careful not to stick them to the couplings.
