Instrument Valve - Tescom Anderson Greenwood

Instrument valves isolate, vent and control flow to gauges, transmitters and analyzers. They give technicians safe access for maintenance and calibration.

Instrument Valve Types

  • Needle valves – precise flow control and isolation
  • Ball valves – quick quarter-turn shutoff
  • Block and bleed valves – isolate and vent in one body
  • Gauge valves – compact isolation for gauges
  • Check and relief valves – protect instrument lines

Choosing an Instrument Valve

Match pressure and temperature ratings, materials and connections. Choose seat materials for the media and temperature.

Centro supplies instrument valves for instrumentation and sampling.
