Features

• The positioner provides accurate, fast response and can withstand the vibrations of most plant environments.
• With the cover removed, zero span and cross-over adjustments are easily accessible and can be made with a screw driver.
• Easily adjustable minor loop gain fine tunes the positioner to optimize dynamic response for each specific actuator size and application.
• Changes in supply pressure have minimal effect on positioner operation.
• Case, components, and gasket materials withstand harsh environments. Positioner bleed air purges internal parts and actuator housing for additional protection.
• Simple adjustments permit switching between direct and reverse action; no additional parts are required.
