Johnson Controls DPM18A-602R Diaphragm Kit

The Johnson Controls DPM18A-602R Diaphragm Kit is a critical service component engineered specifically for the V43 Series pressure-actuated water-regulating valves. Designed for high-performance HVACR refrigeration units, this kit allows technicians to recondition the mid-section of the valve assembly without requiring a full body replacement. It is essential for maintaining precise head pressure control in water-cooled condensers, ensuring the system responds accurately to refrigerant pressure fluctuations. As an authentic Penn Controls replacement part, this kit includes the necessary flexible diaphragms and hardware required to restore factory-spec sealing and operational integrity.

For contractors servicing commercial refrigeration systems, the DPM18A-602R is the primary repair solution for V43AV, V43BV, V43CV, and V243GV/HV valve models. Replacing worn diaphragms is a standard preventative maintenance step to prevent internal bypass and external leaks that compromise cooling efficiency. This kit is built for industrial durability, utilizing materials resistant to standard water treatment chemicals and fluctuating thermal loads. Ensure you verify the valve model number prefix before installation to confirm this specific kit matches the 3-inch V43 valve configuration.

Key Benefits

• Optimized Pressure Regulation: Restores the valve's ability to modulate water flow based on refrigerant head pressure for stabilized system performance.
• Broad Compatibility: Specifically designed for Johnson Controls V43 and V243 series valves, including high-pressure azeotropic refrigerant applications.
• Complete Reconditioning: Includes all internal parts required for a full diaphragm section overhaul to ensure a leak-free seal.
• OEM Reliability: Genuine Johnson Controls part ensures precise fitment and eliminates the risks associated with third-party seals.
• Cost-Effective Maintenance: Extends the service life of expensive water-regulating valves by replacing only the wear-sensitive diaphragm components.

Common Questions

Which valve models are compatible with the DPM18A-602R?
This kit is primarily used with the V43AV, V43BV, and V43CV models, as well as several V243 series high-pressure valves. Always check the technical bulletin LIT-125683 for your specific model suffix.

Can I use this kit for potable water applications?
No, these kits are typically constructed from copper alloys and are intended for industrial refrigeration and HVAC condenser water systems, not for drinking water circuits.

Does this kit include the seat disc?
The DPM18A-602R is a diaphragm-specific kit. If your inspection reveals damage to the valve seat, you should consider the DSC16A-602R seat disc and diaphragm kit for a more comprehensive repair.
