ISO7241A, ISO7241B

Features:Double Shut Off Couplings are used extensively when it is important to minimize fluid loss upon disconnections. Both halves of coupler, the body and nipple, contain shut off valves. These valves open automatically when the body and nipple are connected, and close automatically when two halves are disconnection-keeping fluid loss to a minimum.

Bi-directional shut off coupler with an automatic shut off valve built in the socket and plug recommended for piping of chemicals, steam and oil.
Material: Carbon Steel, Brass or Stainless Steel

The working pressure range for Iso7241A is 0-350bar, and the working pressure range for Iso7241B is 0-75bar.
