Two-valve single outlet gauge valves that combine isolating, calibrating, and venting functions into a single unit.
The Anderson Greenwood M25 two-valve single outlet gauge valves combine isolation, calibration, and venting in a single unit. Their compact design minimizes space requirements, and their minimal instrument installation components reduce costs and possible leak points during gauge, transmitter, or switch service. Ball end stem eliminates seat galling and provides bubble-tight shutoff and long life.
