Product Description

Flowserve Automax APEX 8000 positioners may be used to control quarter-turn control valves such as eccentric plug, butterfly, segmented ball, standard ball, and plug valves. The Flowserve Automax APEX 8000’s sensitive two-stage relay also makes it ideal for precise damper control applications.
Specify the Flowserve Automax APEX 8000 positioner whenever valve rotation sensitivity is critical.
The Flowserve Automax APEX 8000 positioner may be installed on any quarter-turn valve actuator conforming to the NAMUR standard for accessory mounting bolt pattern and pinion height without a coupler. This reduces deadband and is less expensive.
The Flowserve Automax APEX 8000 housing is constructed from durable die-cast aluminum. The housing is anodized for internal corrosion resistance, then coated with epoxy powder for external resistance to harsh chemicals
Features:
Two-Stage Pilot Relay provides fast, sensitive response characteristics for precise control of critical control valves and dampers.
Non-interactive Span Adjustment reduces calibration time.
Adjustable Gain allows positioner sensitivity adjustment for a wide range of valve/actuator applications.
Corrosion Resistant Materials. All exposed parts are either stainless steel or epoxy powder coated anodized aluminum to permit use in corrosive environments.
Optional UltraDome Visual Position Indicator provides adjustable, high-contrast, full-angle viewing of valve position.
Field Upgradable. The Automax APEX 8000 is field-upgradable to a number of electro-pneumatic options without removing the cover. Limit switches or a 4-20 mA position transmitter may be installed with basic tools.
Vibration Resistant. High natural frequency and pneumatic dampening make the Automax APEX 8000 unaffected by vibrations with accelerations up to 2 G’s and frequencies to 500 Hz.
