Johnson Controls V-9999-6002 Spring

Ensure precise modulation in your terminal unit applications with the Johnson Controls V-9999-6002 spring kit. Specifically engineered for VT Series valves utilized with V-3802 and V-4000 pneumatic actuators, this heavy-duty replacement spring provides a reliable 4-8 psi operating range. As a veteran technician knows, maintaining the correct spring tension is critical for achieving a consistent 5/16 inch stroke and ensuring the valve returns to its fail-safe position. This kit is a direct OEM replacement part designed to handle media temperatures up to 281?F, making it suitable for both steam and hot water systems. The pneumatic valve spring assembly is vital for field-mounting actuators to the valve bonnet, allowing for seamless integration without compromising the actuator seating pressure. When your pneumatic control signal must translate into accurate mechanical force, trust this HVAC valve repair part to maintain system equilibrium and prevent unintended cycling or leakage in tight-clearance mechanical spaces.

• Precision Control: High-tolerance 4-8 psi range ensures accurate response to pneumatic signals for stable temperature regulation.
• System Compatibility: Purpose-built for Johnson Controls VT Series valves and V-3802 oval top actuators, eliminating the guesswork of field retrofits.
• Durable Construction: Built to withstand commercial HVAC environments with a maximum media temperature rating of 281?F.
• Optimized Stroke: Maintains the standard 5/16" travel required for proper modulating plug positioning in terminal units.

• Is this spring compatible with VG7000 Series valves? No, this kit is specifically designed for VT Series valves and is not intended for use with the VG7000 line.
• Do I need specialized tools for installation? While standard tools like a screwdriver and pliers are required, always ensure the pneumatic line is disconnected and pressure is relieved before removing the actuator set screw.
• Can this be used with V-4000 actuators? Yes, the V-9999-6002 is verified for use with both V-3802 and V-4000 series oval top pneumatic actuators.
