Spence Engineering 07-07752-01 Repair Kit

When the Spence Engineering 07-07752-01 2" E-Valve Repair Kit is on your bench, you are looking at a complete rebuild solution for the Spence Type E Main Valve. This kit is engineered specifically for 2-inch full port regulators, common in high-demand steam pressure reduction and temperature control stations. The Type E repair kit components—including the stainless steel diaphragms, hardened seat ring, and stem assembly—provide the precise tolerances required for the normally closed, pilot-operated architecture. Replacing the main valve spring and high-pressure gaskets ensures consistent seat-to-disc alignment, preventing the common "hunting" or erratic pressure delivery issues caused by worn internals. This OEM rebuild kit is the standard for maintaining Spence steam regulators in industrial and institutional boiler plants, offering a direct path to restoring factory-spec performance without replacing the entire 250 PSIG rated cast iron body.

Key Benefits

• Restores leak-tight shutoff and prevents steam wire-drawing across the seat.
• Comprehensive assembly includes SST diaphragms, valve stem, and disc for a complete internal overhaul.
• Optimized for the Spence 2-inch E-Main Valve, ensuring exact compatibility with existing 125# or 250# flange configurations.
• Maintains the packless construction integrity, reducing long-term maintenance cycles in high-pressure steam service.

Common Questions

What is included in the 07-07752-01 kit?
This complete internal rebuild kit includes the valve stem, two stem nuts, seat ring, valve disc, high-pressure spring, two stainless steel diaphragms, pressure plate, and necessary gaskets.

Will this work with the E2 Main Valve?
While similar, this kit is specifically designed for the standard Spence Type E 2-inch full port valve. The E2 series may utilize different diaphragm materials or configurations; always verify the valve nameplate before installation.

How do I know if my seat ring needs replacement?
If the regulator fails to shut off tightly or "creeps" past the set point during low-load conditions, the hardened stainless steel seat ring included in this kit should be installed to ensure a proper seal.
