Double Shut off Pneumatic Coupling


HD Series

B.S.Hydro manufactures Double shut off type HD series of Quick coupling. HD series is designed with Poppet valve on both halves of coupling and a captive ball locking arrangement. HD series of Quick couplings are used in industrial hydraulics, Gas, utility and similar other applications

Working principal

HD series type Double shut off hydraulic quick coupling work on simple Push and Pull principle. When the Adaptor is pushed to the coupler, it is accurately held by the self locking arrangement resulting in a positive & leak proof connection. This action simultaneously opens the valve & fluid flow starts. When sleeve is pushed back, the coupler releases the adaptor, simultaneously shutting off the poppet valves.
