D-9502-612 Johnson Controls Spring EXTENSION

Overview

The Johnson Controls D-9502-612 is a genuine replacement positioner spring designed for use with pneumatic actuators and positioners, such as the D-3246 series pneumatic damper actuators and V-9502 pneumatic valve actuator positioners. This heavy-duty helical extension spring works in conjunction with a lever arm assembly to impose a balancing force against control pressure, ensuring precise modulation and positioning.

Features

• Heavy-duty construction manufactured from high-tensile helical steel for superior resistance to fatigue
• Direct-fit replacement solution for worn or stretched springs to maintain original factory calibration
• Enables precise field calibration of the operating span and starting point on pneumatic assemblies

Specifications

• Component Type: Helical Extension Spring
• Model Number: D-9502-612
• Weight: 0.8 lbs (0.36 kg)
• Dimensions: 2 x 2 x 2 inches
• Stroke Compatibility: 3/4 inch valve or actuator stroke applications

Applications

• Specifically calibrated for integration into D-3246 Series pneumatic damper actuators and V-9502 pneumatic valve actuator positioners.
• Used in commercial building automation and HVAC pneumatic control systems to regulate and adjust field-selectable operating spans from 3 to 13 psi.
