Powers Commercial 230-137 Replacement Kit

The Powers Commercial 230-137 Replacement Kit is a field-standard solution for maintaining the structural and operational integrity of HydroGuard XP Series master mixing valves. Specifically engineered for Powers Model 433 and 434 checkstops, this kit addresses common failure points such as leaking, low flow, or cross-contamination between hot and cold water supplies. As a triple duty checkstop repair kit, it combines the functionality of a shutoff, a strainer, and a check valve, ensuring optimal thermostatic mixing valve performance in high-demand commercial environments. Each kit includes a high-grade poppet assembly, replacement spring, gasket, and O-ring, providing all the components required for a complete rebuild. Designed to handle intense hydraulic conditions, the assembly is rated for a maximum pressure of 125 psi and temperatures up to 160°F. Utilizing this OEM replacement part ensures ASSE 1017 compliance and maintains the precise temperature regulation required by commercial plumbing codes.

• Universal Compatibility: Fits Powers HydroGuard 433, 434, and 1434 series checkstops for streamlined inventory management.
• Enhanced Flow Stabilization: The heavy-duty poppet and spring assembly eliminates vibration and ensures consistent water pressure across the mixing chamber.
• Prevents Thermal Cross-Flow: Restores the check valve’s ability to prevent hot water migration into cold lines during high-differential pressure events.
• Extended Service Life: Features high-temp gaskets and specialized O-rings resistant to lime scale and mineral buildup common in commercial HVACR systems.

Which mixing valve models are compatible with the 230-137 kit?
This kit is specifically designed for the Powers 433 and 434 series HydroGuard Master Tempering Valves. It is not interchangeable with 431 or 432 series parts, which require the 230-135 kit.

What are the symptoms of a failing checkstop poppet?
Technicians typically observe temperature fluctuations at the fixture, reduced GPM flow rates, or "bleeding" where hot water migrates into the cold supply line when the valve is in a static state.

Does this kit include the strainer screen?
No, the 230-137 is the checkstop repair kit (poppet, spring, gaskets). If you require the strainer screen replacement, you must order the 230-136 kit separately.
