The Apex 5000 Pneumatic Positioner provides accurate valve positioning with advanced features. It may be used with 3-15 psi pneumatic control signals, or fitted with a current-to-pressure tranducers for 4-20 mA signal input (See Apex Electro-Pneumatic Positioner). The Apex is available with many options including: limit switches, position feedback transmitter, speed controls, NAMUR shaft, and our Pharos visual position indicator.

Three spool valve options plus an adjustable gain system make the Apex well suited for use with all pneumatic rotary actuator types including: Rack-and-Pinion, Heavy Duty, Vane, and others. The Apex is equally well-suited for use with pneumatic linear actuators and cylinders. The Apex may be installed on any actuator conforming to the NAMUR standard. Automax also offers a full line of mounting hardware for non-NAMUR actuators.

The Apex housing is constructed from durable die-cast aluminum and treated with a dichromate undercoat and polyester powder top coat for protection against the toughest applications in all process industries.
