2 Valve Venting Gauge Valve P2/VGV series

PRECISION Valves are designed, built & tested to rigorous standards, & provide bubble tight sealing across the pressure/temperature curve. The PRECISION Venting Gauge Valve Series allow for isolation of the instrument from process, and a separate Vent Valve with ¼” Female NPT outlet to allow safe venting of pressure trapped between isolation valve and instrument. This also allows in-situ calibration options.
