Two-valve single outlet gauge valves that combine isolating, calibrating and venting facilities in a single compact unit.
Versatile two-valve static pressure manifolds with a variety of inlet and outlet connections that enable isolation, calibration and venting in single unit. Specifically designed for use with pressure transmitters, gauges and switches in liquid and vapor service, all models are ideal for instrument isolation and provide the ability to vent or calibrate to a separate threaded port.

M9 block and bleed valves are suitable for isolation and venting of static pressure gauge and instrument installations.
