Johnson Controls V-9502-100 Positioner Spring

The Johnson Controls V-9502-100 is an essential positioner spring engineered for precise integration with V-3000 actuated valves. Designed for heavy-duty pneumatic systems, this component ensures stable and accurate control by providing a fixed operating span tailored to specific stroke lengths. For a 1/2-inch stroke, it provides a 3.6 PSI span, while a 3/4-inch stroke configuration yields a 5.1 PSI span. By translating control signal changes into mechanical force, the V-9502-100 maintains the valve at the exact position dictated by the controller, effectively counteracting flow surges and external piping pressure. This pneumatic valve actuator accessory is critical for technicians performing valve sequencing or recalibrating HVAC control systems. Its durable construction meets the rigorous demands of commercial HVAC maintenance, ensuring long-term repeatability in pneumatic valve positioners. Whether for direct-mounted actuators or field service, this spring is the OEM replacement part needed to restore secondary starting point accuracy and signal responsiveness.

• Precise Signal Response: Maintains actuator stability by providing exact mechanical feedback to the V-9502 positioner.
• Optimized Compatibility: Specifically designed for the Johnson Controls V-3000 series, eliminating guesswork in spring range selection.
• Simplified Sequencing: Facilitates accurate valve sequencing through reliable pneumatic pressure span control.
• Field-Serviceable Design: Easy to identify and install within the positioner cover for fast HVAC repairs.

What is the pressure span for the V-9502-100 on a 1/2" stroke?
When used with a 1/2-inch stroke, this spring provides a fixed 3.6 PSI span to the actuator.

Is the operating span adjustable for V-3000 series valves?
On V-3000 actuators, the operating span is fixed by the specific spring used; the V-9502-100 is chosen when a 3.6 PSI or 5.1 PSI span is required for the stroke length.

Does this part include the mounting hardware?
No, this is the positioner spring only. Mounting kits and positioner assemblies for pneumatic valve actuators must be ordered separately if needed for a full installation.
