Johnson Controls V-9502-6802 Positioner Spring

The Johnson Controls V-9502-6802 Positioner Spring is a critical component for technicians maintaining V-3000 Series Pneumatic Actuators. Designed for precision and reliability, this pilot spring ensures the actuator responds accurately to control signals by providing a dedicated operating span tailored to specific valve stroke requirements. When installed in V-3000 Actuated Valves, the V-9502-6802 delivers an 8 PSI span for 5/16" strokes and a 12 PSI span for 1/2" strokes, allowing for stable modulation and linear stem travel even under varying load conditions.

For contractors managing pneumatic control systems, this high-performance tension spring is essential for valve sequencing and overcoming friction or differential pressure that can lead to hysteresis. It is specifically compatible with the V-3000-8001 and VG7000 series bronze control valves. By integrating this genuine Johnston Controls HVAC part, you ensure that your pneumatic valve positioner maintains its calibration, preventing erratic movement and extending the service life of the entire assembly in demanding industrial or commercial HVAC applications.

• Ensures accurate pneumatic valve positioning for 5/16" and 1/2" stroke configurations.
• Optimized for V-3000 series actuators to provide 8 PSI and 12 PSI pressure spans.
• Assists in overcoming stem friction and external forces for precise flow control.
• Facilitates reliable valve sequencing in complex HVACR pneumatic loops.
• Direct OEM replacement part ensures mechanical compatibility and easy field installation.

Which actuators are compatible with the V-9502-6802?
This spring is specifically engineered for use with Johnson Controls V-3000 series pneumatic actuators, including the V-3000-8001, commonly found on VG7000 valves.

How do I determine the correct PSI span for my application?
The span is dictated by the valve stroke: use this spring for an 8 PSI span on a 5/16" stroke or a 12 PSI span on a 1/2" stroke to ensure proper calibration.

Can this spring be used to fix erratic valve hunting?
Yes, replacing a worn positioner spring often resolves issues where the valve fails to reach its commanded position due to loss of tension or incorrect span signals.
