• Can be used to shut off Maximator® pumps, air amplifiers and gas boosters, with pilot ports, by controlling the pneumatic signal to the air pilot line. Allows the pump, amplifier or booster to operate at maximum air drive pressure, achieving the desired outlet pressure as rapidly as possible with little overshoot.
  • Ideal for use as an on/off control device for air operated actuators and pilot operated valves in process control applications.
  • Replaces electrical switches in hazardous liquid or gas services.
  • Precise and repeatable control of outlet pressure.
  • Senses gas or liquid pressures.
  • Externally adjustable under pressure.
  • Reliable and easy to install.
