Johnson Controls V-9502-20 Spring

The Johnson Controls V-9502-20 is a high-precision pneumatic positioner spring engineered for seamless integration with V-3000 series pneumatic valve actuators. Designed specifically for industrial and commercial HVAC applications, this spring ensures consistent feedback and accurate valve stroke control. By providing the mechanical resistance necessary to counteract air pressure signals, it allows for finite modulation in complex hydronic and steam systems. As a veteran-grade HVAC part, it is built to maintain tension under high-cycle operations without losing its calibrated range, which is essential for maintaining system efficiency and protecting your pneumatic actuator from overshoot.

This technical component is critical for multi-stage valve sequencing and applications requiring tight pneumatic control. The V-9502-20 is optimized for reliable performance when installed on Johnson Controls valve actuators, specifically those utilizing the V-9502 positioner assembly. Its linear compression rate is strictly manufactured to match the following operational parameters for actuated valves:

• Optimized Span Control: Specifically calibrated for a 3 PSI span with a 5/16" stroke, a 4 PSI span with a 3/8" stroke, and a 5 PSI span with a 1/2" stroke.
• Durable Construction: High-tensile spring steel provides long-term reliability in varying HVACR environments (-20°F to 150°F).
• Compatibility: Direct replacement for worn or fatigued springs in V-3000 series setups, ensuring your HVAC control systems remain in calibration.
• Enhanced Precision: Minimizes hysteresis and ensures the valve stem maintains the exact position dictated by the controller signal.

Common Questions

Which valve actuators are compatible with the V-9502-20 spring?
This spring is designed for use with Johnson Controls V-3000 Series actuators equipped with a V-9502 pneumatic positioner. It is suitable for different stroke lengths including 5/16", 3/8", and 1/2".

How does the stroke length affect the PSI span?
The span is determined by mechanical leverage within the positioner. For this model, a 5/16" stroke correlates to a 3 PSI span, while longer strokes like 1/2" produce a 5 PSI span.

Can this spring be used in high-temperature environments?
Yes, the Johnson Controls V-9502-20 is rated for standard commercial HVAC ambient temperatures ranging from -20°F to 150°F, making it resilient for most mechanical room conditions.
