Johnson Controls STT17A-610R Seat Repair Kit

The Johnson Controls STT17A-610R Seat Repair Kit is a professional-grade renewal solution engineered specifically for 1-1/4 inch and 1-1/2 inch V46A, V46D, V47A, and V47N series valves. In commercial refrigeration and HVAC service, valve seats and rubber discs frequently become worn, pitted, or "wire drawn" after extended operation, leading to a loss of sealing integrity and internal bypass. This OEM water valve renewal kit provides the critical internal components—including the seat, disc, and diaphragms—necessary to recondition pressure-actuated water regulating valves and restore factory-spec modulation. Designed for use in systems with water-cooled condensers and industrial cooling loops, the STT17A-610R ensures reliable head pressure control and prevents the waste of cooling water during compressor standby. Utilizing genuine Johnson Controls replacement parts is essential for maintaining the precise opening point and pressure range specifications required in high-demand commercial environments, extending the operational life of the existing valve body without the need for full piping replacement.

Key Benefits for Technicians

• Restore Sealing Integrity: Eliminates "wire drawing" and pitting issues that prevent the valve from closing off completely.
• Broad Series Compatibility: Fits 1-1/4" and 1-1/2" STT17A-610R applications for V46 and V47 series regulators.
• OEM Precision: Genuine Johnson Controls STT17A-610R components ensure exact fitment and reliable diaphragm response.
• System Efficiency: Restores proper refrigerant head pressure control in water-cooled condenser systems.
• Cost-Effective Maintenance: Avoids expensive valve body removal and re-piping by replacing only the internal wear components.

Common Questions

What is included in the STT17A-610R renewal kit?
This seat repair kit includes the valve seat, rubber disc, diaphragms, and the necessary internal seals and gaskets required for a complete top-to-bottom reconditioning of the valve assembly.

How do I know if my V46 or V47 valve needs a seat repair?
Common indicators include the inability to shut off water flow during compressor off-cycles, erratic head pressure modulation, or visible leaking from the valve weep holes, suggesting diaphragm or seat failure.

Can this kit be used for ammonia or maritime valves?
The STT17A-610R is designed for commercial type V46 and V47 valves using standard, non-corrosive refrigerants. For maritime models with Monel trim or ammonia-specific valves, verify compatibility with the specific model's suffix before installation.
