Johnson Controls V-9502-95 Positioner

The Johnson Controls V-9502-95 Positioner is a precision pneumatic valve actuator positioner designed to provide accurate proportional positioning for V-3000, V-4000, and V-5000 series actuators. This non-relay type unit operates on a pneumatic control signal to ensure the valve stem position corresponds exactly to the controller output, effectively overcoming friction and high pressure drops that cause hysteresis. Engineered for HVAC process control, the V-9502-95 features a rugged construction suitable for demanding mechanical rooms. It is a critical component for modulating valve control where precise flow regulation is required. This specific model is supplied without spring and mounting hardware, necessitating the use of existing hardware or a compatible V-9502 mounting kit for installation. Field technicians value this positioner for its straightforward calibration and reliable pilot-operated pneumatic performance in legacy and modern pneumatic infrastructures.

• Precise Stem Positioning: Minimizes hysteresis and ensures accurate flow rates in proportional control loops.
• Field Versatility: Compatible with a wide range of Johnson Controls pneumatic actuators for steam and chilled water valves.
• Simplified Maintenance: Rugged design allows for consistent operation in high-vibration HVACR environments.
• Direct/Reverse Action: Easily adjustable to meet specific pneumatic sequences and system requirements.

Common Technical Questions

Does this unit include the feedback spring?
No, the V-9502-95 is a replacement positioner body only and does not include the feedback spring or the actuator-specific mounting bracket.

How do I calibrate the starting point?
Calibration is performed via the adjustment screw to align the beginning of the stroke with the desired psi control signal, typically 3, 5, or 8 psi depending on the application.

Can this be used on non-Johnson Controls actuators?
While designed for JCI V-series actuators, it can be adapted to other pneumatic valve assemblies provided the appropriate linkage and feedback spring are utilized.
