Design and Applications

D-Pro VBV Series Bleed Valves are designed to vent the signal line pressure to atmosphere before an instrument is removed and to assist in calibration of control devices. These are for use on instrumentation devices such as gauge root valves and multi-valve manifolds. Optional barbed vent tube enables containment of fluid vented. The V BV Series a re a lso i deal in b leeding h ydraulic systems.

Installation and Operation

Position the vent tube so that system fluid is not directed to personnel operating. Slowly open the valve. This valve has no s tem seal packing; s mall amounts of fluid will go through the stem thread when they are opened. Therefore suitable measures should be taken to protect personnel operating.
