Description
The VEPHD (Heavy Duty) Series offers the same features of the VEP series, with upgraded material, a yellow o-ring visual ID, and larger mating areas. Like the VEP, the VEPHD is a popular solution for hydraulic circuit applications subject to high pressure impulses and circuits which experience high residual or trapped pressure in a line, offered in a more durable, higher grade of steel and all QPQ plating for increased longevity. The “VEP-HD” screw flat face coupling series is another example of the continuous improvement of Stucchi products. Designed for heavy duty applications with high operating pressure, high impulse frequency, and mechanical stress. The “VEP-HD” quick couplings are manufactured in high resistance carbon steel material treated with special nitriding treatment to increase the wear resistance of the coupling. This series has been tested to 1’000′ 000 impulse cycles. The triple valve system allows a connection of the coupling safely even in presence of high internal residual pressure and at the same time avoiding fluid loss during the connection-disconnection process.
