Johnson Controls VG74K1NT Reconditioning Kit

For contractors servicing 1-inch Johnson Controls VG7441NT series valves, the VG74K1NT Reconditioning Kit is the professional solution for restoring factory-spec performance without a full body replacement. This kit is specifically engineered for 2-way normally closed, push-down-to-open (PDTO) valve bodies featuring an 11.6 Cv flow coefficient. By utilizing this OEM valve repair kit, you ensure the preservation of equal percentage flow characteristics, which is critical for precise modulating control in hydronic heating and cooling systems.

The VG74K1NT package includes high-grade brass trim components and a threaded stem assembly, designed to withstand the mechanical stresses of high-duty cycle HVAC applications. Field-proven for its reliability, this reconditioning kit allows technicians to address internal wear, such as weeping or seat leakage, while maintaining the original valve's 1-inch NPT connection integrity. It is compatible with all standard pneumatic and electric actuators except for the V-3801, VA-8x2x, V-500, and MP84 series. Focus on restoring seat tight-shutoff and linear response times by replacing the entire internal cage assembly with these precision-machined parts.

• Optimized Flow Precision: Restores the 11.6 Cv rating and equal percentage curve for accurate temperature staging.
• Durable Brass Trim: High-quality brass internals offer superior resistance to scale and corrosion in closed-loop systems.
• Reduced System Downtime: Rapid internal replacement keeps the 1-inch valve body in-line, eliminating the need for heavy pipework modifications.
• Threaded Stem Compatibility: Ensures a secure, slip-free mechanical connection with compatible Johnson Controls actuators.

• Is this kit compatible with 3-way mixing valves? No, the VG74K1NT is specifically designed for 2-way normally closed (push-down-to-open) valve configurations only.
• What tools are required for installation? A standard service wrench set and stem adjustment tools are typically sufficient to swap the internal trim once the actuator is removed.
• How do I verify if my valve needs reconditioning? If you observe bypass leakage when the valve is in the closed position or inconsistent flow at low demand, the internal seals or plug are likely compromised.
