Stafsjo TV Isolation Knife Gate Valves for Transmitters or Sensors

Stafsjo’s TV knife gate valves are for isolating the sensor or transmitter on the tank. They allow for removal of the transmitter or sensor without draining the tank contents.

TV knife gate valves come with a ratchet wrench actuator that allows for direct installation on the tank and easy operation despite wall installation. They come in 3" size and meet MSS SP-81 face-to-face dimension.
