HNR-VEP Flat Face series

    APPLICATION

    ● The VEP series couplings are widely used in mobile engineering equipment, hydraulic tools, vehicles, and other public utilities.

    FEATURES

     The new valve design can withstand the impact of high-speed fluids and pulse pressure, providing higher performance.
     The male coupling is designed for pressurized operation,allowing for pressurized connections even when there is residual high pressure inside.
     The VEP series female coupling uses a threaded sleeve locking structure, which pairs with the corresponding external threads on the male plug. During connection, the male and female parts must be manually joined together using the threads.
      A new environmentally friendly galvanized coating provides enhanced rust resistance.
     The VEP series couplings operate with a flush valve mechanism during connection and disconnection.
     This means the connection minimizes fluid loss during disconnection or introduces only a small amount of air when reconnecting.
     The explosion-resistant BFT seal is designed to prevent rupture or damage under hazardous working conditions. Made from solid steel bar stock, the couplings offer excellent durability.
