Johnson Controls ROD18A-601R Push Rod Kit

The Johnson Controls ROD18A-601R Push Rod Kit is a critical replacement component engineered for the repair and maintenance of pilot-operated water regulating valves. Specifically designed for 2-1/2" and 3" V43 and V243 series valves, this kit ensures precise mechanical transmission between the pressure-actuated sensing element and the valve’s internal throttling mechanism. In heavy-duty commercial refrigeration and HVACR systems, the ROD18A-601R is vital for maintaining responsive head pressure control by modulating water flow through the condenser based on refrigerant demand. Our veteran technicians emphasize that a valve push rod replacement should typically be performed as part of a comprehensive overhaul. Per manufacturer specifications, installing this HVAC valve repair kit requires the simultaneous replacement of either the seat repair kit or the diaphragm kit to ensure a proper seal and prevent premature failure under high-pressure conditions. Utilizing OEM Johnson Controls parts for these commercial water valves guarantees compatibility with non-corrosive refrigerants and ensures the assembly can withstand the mechanical stresses of continuous service.

• Ensures accurate modulating valve operation for consistent system head pressure.
• Precisely sized for V43A and V243 series valves in 2.5-inch and 3-inch configurations.
• Facilitates a complete refrigeration valve rebuild when paired with compatible seat or diaphragm kits.
• Durable construction designed to meet the rigorous demands of industrial HVACR maintenance.

Which valve models are compatible with the ROD18A-601R?
This push rod assembly is specifically matched to the Johnson Controls V43 and V243 series pressure-actuated valves with pipe sizes of 2-1/2" and 3".

Is this kit sufficient for a full valve repair?
No, for a reliable HVAC system repair, technical documentation dictates that you must also replace the seat or diaphragm kit when installing a new push rod to maintain the internal integrity of the regulating valve.

Can I use this for maritime or corrosive applications?
While the rod provides the mechanical link, always verify if your specific valve body requires monel interior trim or maritime-grade components before proceeding with the installation.
