Spence 08-08567-01 Repair Kit

For veteran technicians maintaining high-pressure steam systems, the Spence 08-08567-01 is the definitive overhaul solution for 3-inch Type E Main Valves. This comprehensive 3" E-Valve Repair Kit is engineered to restore the packless, pilot-operated performance required in demanding industrial environments. The kit addresses common failure points such as steam pressure regulator hunting and failed valve closure by providing precision-machined internal components. The package includes a high-grade valve stem, two stem nuts, a durable seat ring, and a matched disc for tight shut-off. To ensure responsive modulation, the kit also features two stainless steel SST diaphragms, a rugged pressure plate, and a high-temperature replacement gasket. By utilizing this OEM-spec rebuild kit, contractors can eliminate the risk of oversized steam bypass and ensure the single-seat, balanced design operates at peak thermal efficiency. This 3-inch Spence valve maintenance kit is essential for preventing seat leakage and maintaining consistent delivery pressure across secondary steam lines.

• Industrial Durability: Features stainless steel diaphragms designed to withstand thermal cycling and high-pressure steam service.
• Fail-Safe Sealing: High-precision seat and disc components prevent steam valve leakage and downstream pressure creep.
• Standardized Compatibility: Specifically engineered for Type E full port main valves, ensuring a perfect mechanical fit without field modifications.

Common Questions

What causes a Spence 3-inch E-Valve to overshoot its set pressure?
Overshooting is typically caused by debris trapped in the seat or a compromised diaphragm. Installing the Spence 08-08567-01 Repair Kit replaces the worn seat and disc, ensuring the valve closes completely when the pilot throttles the loading pressure.

Are the diaphragms in this kit suitable for high-temperature steam?
Yes, this Spence valve rebuild kit includes two stainless steel (SST) diaphragms specifically designed for the high-temperature and high-pressure requirements of industrial steam systems.

How do I know if the main valve stem needs replacement?
If you observe erratic valve movement or "hunting," the stem may be scored or bent. Replacing the stem and the provided stem nuts ensures smooth travel and prevents binding within the valve body.
