pneumatic positioner 7400

The primary function of the masoneilan 7400 series valve positioner is to insure that the control valve plug position is always directly proportional to the value of the controller output pressure, regardless of packing box friction, diaphragm actuator hysteresis or off-balance forces on the valve plug.

These positioners also provide a convenient and accurate means of changing the effective output signal range of a controller and/or changing the valve action.
