Resideo TK30PV100NK Combo Trim Kit

The Resideo TK30PV100NK Combo Trim Kit is a comprehensive, field-ready solution engineered for professional boiler change-outs and hydronic system upgrades. This 4.4-gallon kit integrates critical components into a high-performance assembly, featuring a hydronic expansion tank, a 1-inch NPT SuperVent air eliminator, and a NK300S boiler feed combination valve. Designed for closed-loop heating systems, the ASME-compliant diaphragm expansion tank effectively manages thermal expansion to maintain stable system pressure. The PV100 SuperVent utilizes a high-efficiency micro-bubble concentrator to strip entrained air, significantly reducing noise and preventing pump cavitation. By utilizing the SCV-050 service check valve, technicians can perform maintenance or swap tanks without draining the entire loop, minimizing downtime. This kit serves as an essential boiler trim kit for contractors seeking a streamlined, reliable installation that fits into tight mechanical room footprints.

Key Benefits for the Contractor

• Optimized Pressure Control: The 4.4-gallon hydronic expansion tank features a welded construction—not clamped—ensuring a leak-proof life cycle in high-demand residential systems.
• Efficient Air Removal: The 1-inch NPT SuperVent provides superior micro-bubble elimination, protecting heat exchangers and preventing oxygen-related corrosion.
• Simplified Installation: Combining the pressure-reducing valve, backflow preventer, and shut-off valves into a single NK300S boiler feed valve reduces the number of potential leak points and pipe connections.
• System Protection: Includes a high-accuracy pressure gauge for real-time monitoring of static and operating hydronic pressures.

Common Questions & Technical Support

• What is the maximum operating temperature for this kit? The system is rated for a maximum operating temperature of 240°F (115°C) and a safe operating pressure of up to 100 psi.
• Does the NK300S include a backflow preventer? Yes, the NK300S-100 features an integrated double-check backflow preventer with an air vent to protect the potable water supply.
