Design and Applications:

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 VBV Series are also ideal in bleeding hydraulic systems. Factory Test: Every valve is tested with the nitrogen @ 68 bar (1,000 psi) for leakage at the seat to a maximum allowable leak rate of 0.1 scc/min.

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 stem seal packing; small amounts of fluid will go through the stem thread when they are opened. Therefore suitable measures should be taken to protect personnel operating.
