Are there any KK□ series S couplers with check valves on both the socket and plug sides?
-
KKA series S couplers can be selected with check valves on both the socket and plug sides.
The check valve is a mechanism that prevents the flow from leaking from the coupler when the coupler socket and plug are separated.
For KK, KKH, and KK130 series S couplers, there is only a check valve mechanism on the socket side.
Piping this socket to the upstream side of the fluid stops the flow from upstream when the coupler is separated.
Note) The KK□ series S coupler cannot be used as a stop valve that requires zero leakage. Due to the specifications of the product, a certain amount of leakage is unavoidable.
