Allows connection of the female body to the male tip while either or both are under pressure. At time of connection, valves in both halves remain closed, opening only when system pressure has been relieved in the female body and then reapplied. The double-acting sleeve permits easy, one-handed connection to a clamp mounted female body. May be used with either open center or a closed center system that has a control valve. Pressures to 2500 PSI.
