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.
    Twin valve TypeTwin valve Type
    • 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.
