PRECISION Valves are designed, built & tested to rigorous standards, & provide bubble tight sealing across the pressure/temperature curve. The PRECISION Multiport 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. Further, it features 3 outlets providing a great deal of flexibility in adding other instruments or in-situ calibration.
