Johnson Controls STT15A-602R Repair Kit

When you're dealing with a weeping or non-responsive water regulating valve, the Johnson Controls STT15A-602R Penn Seat Repair Kit is the essential service component to restore factory-spec performance. This genuine OEM renewal kit is specifically engineered for 1/2 inch threaded pressure-actuated water regulating valves, including the widely utilized V46A, V46N, and V47A series. Instead of pulling the entire valve body and disrupting the piping, this STT15A-602R repair kit allows technicians to replace high-wear internal components efficiently. The technical package typically includes a precision-machined valve seat, disc assembly, and the diaphragm needed to maintain a tight seal and accurate modulating control. By addressing internal scale buildup or elastomer fatigue with this seat repair kit, you ensure the system maintains the correct head pressure in water-cooled condensers and heat pump applications. Relying on original PENN service parts ensures critical compatibility with V46AA-1C, V46NA-1C, and V47AA-1C models, preventing the common bypass issues found with generic substitutes.

• Direct Compatibility: Engineered specifically for 1/2" V46 and V47 series pressure-actuated valves to ensure a seamless drop-in fit.
• Restores Modulation: Replaces worn seat discs and diaphragms to fix hunting or failing modulation in water-cooled systems.
• Reduced Downtime: Complete renewal kit allows for rapid field servicing without removing the valve body from the line.
• OEM Reliability: Genuine Johnson Controls Penn components designed to withstand the thermal and mechanical stresses of HVACR water circuits.

Does this kit work on 3/4" or 1" V46 valves?
No, the STT15A-602R is precisely sized for 1/2 inch valve bodies. Using this in larger or smaller valves will result in improper seating and potential leaks.

What is included in the STT15A-602R renewal kit?
This kit contains the primary hardware required to rebuild the internal assembly, including the seat, disc, and diaphragm, which are the most common points of failure in PENN water valves.

Can I use this for both V46 (direct-acting) and V47 (reverse-acting) valves?
Yes, this seat repair kit is designed to service both V46 and V47 series 1/2" models, as the internal seat and disc dimensions are consistent across these pressure-actuated platforms.
