Design
D-Pro VPV Series Purge Valves are designed for manually bleeding, venting, or draining system fluids. The cap is clamped to the valve body for safety in use. The 0.063 inch (1.6 mm) diameter vent hole is constructed on the cap.
Operation and Installation Instruction
D-Pro VPV series purge valve requires a quarter turn of cap with a wrench from finger-tight for a leak-tight seal on the first make-up. To ensure seal to the rated pressure, snug with a wrench. Always open the valve slowly. These valves have no seal on cap. Therefore media may flow through the cap thread when the valves are opened. Operating personnel should take suitable measures to be protected from system fluids.
