Anderson Greenwood (AGCO) M9 Block and Bleed Gauge Valves

The Anderson Greenwood M9 block and bleed valve is the industry standard for the safe, compact, and economical isolation and venting of static pressure gauges and instrument installations. Engineered by TESCOM™ AGI / AGCO, this versatile block and bleed gauge valve features an integral metal-to-metal seated bleed plug, allowing technicians to safely vent pressure without breaking threaded connections.

The compact mini-valve bonnet assembly features a one-piece rotating stem with a ‘V’ tip, available in both hard and soft-seated configurations. The bonnet comes in three designs: an adjustable PTFE stem-packed bonnet suitable for panel mounting via external bonnet threads; an O-ring bonnet assembly with an FKM O-ring seal below the stem thread; and a graphite-packed bonnet for temperatures up to 1000°F (538°C), available on 316 SS valves only. Low-temperature service to -70°F (-57°C) is available on 316 PTFE and graphite-packed bonnets with integral, PEEK, and PCTFE seats, and Delrin® seats are rated to -40°F (-40°C).
