Flowserve Apex 7000 Pneumatic Positioner

Flowserve Apex 7000 Pneumatic Positioner

The Apex 7000 Pneumatic Positioner provides accurate valve positioning for rotary and linear actuators in either double acting or spring return configurations. It may be used with 3-15 psi pneumatic control signals, or fitted with current-to-pressure transducers 4-20 mA signal outputs. The compact, ligthweight positioner also conforms to NAMUR VDI/VDE 3845 mounting standards and features a UltraDome visual position indicator.

  • Corrosion resistant materials
  • Captive cover screws
  • Multiple cam options
  • Compact design
  • Low profile visual indicator
  • Quick and simple calibration

Product Description

The Apex A7000 Pneumatic Positioner provides accurate valve positioning for rotary and linear actuators in either double acting or spring return configurations. It may be used with 3-15 psi pneumatic control signals or fitted with current to pressure transducers for 4-20 mA signal inputs. The modular design of the Apex A7000 allows for field retrofitting of the I/P options. The compact, lightweight positioner also conforms to NAMUR VDI/VDE 3845 mounting standards and features a UltraDome visual position indicator. The Apex A7000 is available with the following options: high and low flow spool valves and multiple feedback cams.
Applications:
Two spool valve options make the Apex A7000 well suited for use with all pneumatic rotary actuator types including: Rack and pinion, Scotch Yoke, Vane, and others. The Apex A7000 is equally well suited for use with
pneumatic linear actuators and cylinders. The Apex A7000 may be installed on any actuator conforming to the NAMUR standard for accessory mountingbolt pattern and pinion height without a coupler. This reduces deadband and is less expensive.

Durable construction and corrosion resistant materials and coatings provide protection against the toughest applications in all process industries, including:

1, Chemical and Petrochemical.
2, Power.
3, Food and Beverage.
4, Pharmaceutical.
5, Municipal and Wastewater.
Features:
1. Corrosion Resistant Materials – All exposed parts are either stainless steel or epoxy powder coated aluminum to permit use in corrosive environments. The gold plated spool valve offers a high degree of protection against moisture laden and/or corrosive supply air.
2. Captive Cover Screws permit calibration without potential for losing screws.
3. Field Upgradeable – The Apex A7000 is field upgradeable to any of the electropneumatic I/P options without removing the cover.
4. Multiple Cam Options – The standard Apex A7000 linear cam allows operation for 0-90°, 0-180°, split ranging, and direct or reverse action applications. Optional characterized cams are available for a wide range of applications.
5. Compact – Rugged Design has few moving parts, adding to its reliability and performance.
6. Low Profile Visual Position Indicator provides high contrast viewing of valve position.
7. Quick and Simple Calibration is done with thumbwheels, requiring only a flat head screwdriver for calibration. The span adjustment is performed internally with an external zero adjustment.

Features

Non-Interactive Span Adjustment reduces calibration time.
Corrosion Resistant Materials. All exposed parts are either stainless steel, or aluminum treated to permit use in corrosive environments.
Captive Cover Screws permit calibration without potential for losing screws.
Optional UltraDome Visual Position Indicator provides fully adjustable,
high-contrast, full-angle viewing of valve position.
Field Upgradeable. The Automax Apex 7000 is field-upgradeable to any of three electro-pneumatic options without removing the cover.
