Johnson Controls V-3974-6009 Spring Kit

When you are servicing pneumatic systems in the field, reliable hardware is non-negotiable for maintaining precise control. The Johnson Controls V-3974-6009 Spring Kit is a direct-replacement service component engineered to maintain the calibrated performance of pneumatic valve actuators. Specifically designed for use with V-3000-1 or V-3000-2 actuators, this kit features a 4-8 psi spring range and supports a 3/4-inch stroke. It is primarily utilized for 1-inch and 1-1/2-inch V-3974 and V-4324 valves, providing the exact compression required for seating and modulation. This professional-grade actuator repair kit includes the tension spring, upper and lower spring seats, a stem extension, and a stem lock screw. Using genuine Johnson Controls parts ensures that your HVAC pneumatic controls maintain their original design specifications and pressure response. Note that removing these springs requires a spring compression tool like the JC 5389 to ensure technician safety and prevent component damage during maintenance cycles.

• Precise 4-8 PSI Range: Engineered to provide consistent force for accurate valve modulation in pneumatic loops.
• Full Stroke Compatibility: Designed for 3/4" stroke applications, ensuring complete valve travel and shut-off.
• Manufacturer Compatibility: Specifically validated for V-3000 Series Actuators and corresponding V-3974 / V-4324 valve bodies.
• Complete Maintenance Solution: Includes critical hardware like the stem extension and spring seats for a thorough rebuild.

• Which valves is this kit compatible with? This kit is specifically sized for 1" and 1-1/2" V-3974 and V-4324 series valves.
• Can I install this without a specialized tool? No, due to the high compression of the spring, a tool like the JC 5389 is required for safe removal and installation.
• Does this fit the smaller 1/2" valve bodies? No, 1/2" valves typically utilize the V-3974-6008 kit. This 6009 model is for the larger 1" and 1-1/2" castings.
