Watts 0875725 Repair Kit

When the 1-1/2" to 2" Series 152A steam pressure regulator begins to bleed pressure or exhibit unstable downstream flow, a comprehensive rebuild is the technical standard for restoring peak performance. The Watts 0875725 Repair Kit is specifically engineered to address internal wear in industrial-grade iron process steam regulators. Utilizing this RK 152A 1 1/2-2 kit ensures that the valve body remains in service, reducing the labor and material costs associated with a full valve replacement. Each component is fabricated from high-grade materials to withstand the rigors of high-temperature steam applications.

This heavy-duty steam pressure regulator repair kit includes the vital internals required to eliminate erratic pressure spikes and seat leakage. The assembly features a high-tensile diaphragm and gasket for airtight sealing, along with a stainless steel strainer to prevent particulate matter from fouling the disc and seat. By replacing the stem, bushing, and bottom spring, technicians can ensure the 152A valve modulates correctly according to system demand. This kit is the standard for contractors maintaining Watts 0830985 and 152A series regulators in steam-fed HVACR and process environments.

• Full Internal Overhaul: Includes stem, bushing assembly, and disc-to-seat components to stop pressure creep.
• Enhanced Filtration: Features a durable stainless steel strainer to protect internal surfaces from scale and debris.
• Precision Modulating: Restores the responsiveness of the bottom spring and diaphragm for accurate PSI control.
• Industrial Compatibility: Purpose-built for 1-1/2" and 2" Watts 152A and 252A iron steam regulators.

What are the signs that my 152A regulator needs a rebuild?
If you notice "swishing" sounds, vibrating pipes, or a consistent pressure rise above the set point during no-flow conditions, the internal rubber components or seat have likely eroded. Replacing the diaphragm and seat with this kit typically resolves these issues.

Does this kit work for both 1.5-inch and 2-inch valves?
Yes, the 0875725 kit is the designated service part for both the 1-1/2" and 2" configurations of the Series 152A steam regulator.

Are special tools required for the 152A-RK installation?
Standard technician tools, such as pipe wrenches and a mallet to break the gasket seal, are usually sufficient. Ensure all steam pressure is fully relieved and isolated before disassembling the valve dome.
