Johnson Controls STT17A-609R Repair Kit

The Johnson Controls STT17A-609R Repair Kit is a professional-grade water valve renewal kit engineered for 1-inch pressure-actuated water-regulating valves. This comprehensive kit is designed to restore factory-spec performance to commmercial type V46A, V46D, V47A, and V47N series valves used in water-cooled condensers and industrial refrigeration systems. As a critical maintenance assembly, the STT17A-609R includes a precision-machined valve seat, high-durability rubber disc, and the necessary diaphragms to ensure a bubble-tight seal and reliable head pressure control. By replacing internal components that have become pitted or wire-drawn over time, HVACR contractors can effectively resolve water regulating valve leakage and prevent bypass issues in high-rise or high-pressure applications up to 350 psi. This OEM Johnson Controls kit eliminates the need for full valve replacement, providing a cost-effective solution for reconditioning refrigeration water valves without compromising system integrity or flow regulation accuracy.

Common Questions

Will this kit fix a valve that won't shut off completely?
Yes. Failure to close is typically caused by a pitted or worn seat and disc. This renewal kit replaces those critical sealing surfaces to restore tight shut-off capability.

Is this kit compatible with V246 or V48 series valves?
While primarily used for V46 and V47 series, technical cross-references often include V246 and certain V48 1-inch models. Always verify your specific valve body casting number before installation.

Do I need special tools for the seat replacement?
Replacing the seat on a 1-inch valve generally requires a seat wrench or appropriate hex stock to ensure the new component is torqued to manufacturer specifications for a leak-free seal.
