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.
