SPE TYPE (PAT.)

Large, Smooth flow and Energy-Saving Type
Medium pressure, Twin valve Type
  • Interchangeable with conventional CSP types.
  • Both socket and plug have automatic shut-off valves for medium pressure applications.
  • Various packing materials enable a wide variety of applications.
Medium pressure, Twin valve TypeMedium 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.

Feature

We developed to minimize pressure loss, by analyzing the flow condition in the inner mechanism.

*Studding 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.

*Flow from socket to plug

Change of seal improved the packing function.

*The move of seal position to the front makes the flow larger and smoother.
