Spence 07-07751-00 Repair Kit

When you're dealing with a pressure regulator that fails to hold set point or shows signs of seat leakage, skipping a full rebuild is a risk no tech should take. The Spence 07-07751-00 Repair Kit provides every critical internal component required to restore the performance of a 1-1/2" Type E Main Valve. This kit is specifically engineered for cast iron, full port configurations, ensuring that the steam pressure reducing valve regains its frictionless operation. It includes stainless steel diaphragms, a high-pressure spring, a precision-ground seat ring and disc, and the necessary stem assembly to eliminate hunting and overshoot issues. Replacing these wear parts during scheduled steam valve maintenance is the most effective way to prevent costly downtime and maintain the integrity of the pilot-operated regulator system. By installing the provided pressure plate, gasket, and dowel pin, you ensure a tight seal and reliable replacement parts for Spence E valves that meet original factory tolerances.

• Full Port Compatibility: Specifically sized for 1-1/2" Type E cast iron main valves to ensure unrestrictive flow and precise pressure control.
• Enhanced Durability: Includes stainless steel diaphragms and a hardened seat ring to withstand high-velocity steam and thermal cycling.
• Comprehensive Rebuild: Provisions for a complete internal overhaul, eliminating the need to source individual stem nuts or springs separately.
• Reduced Maintenance Intervals: Restores the valve to a "like-new" state, minimizing the frequency of system recalibrations and troubleshooting.

• How do I know if my main valve requires a full repair kit? If the regulator is overshooting its set pressure or if steam continues to pass when the pilot is closed, the seat or disc is likely wiredrawn or fouled, requiring the replacements found in this kit.
• Can this kit be used for Type E2 valves? While Type E and E2 share many design characteristics, always verify your specific model number. This kit is optimized for the standard 1-1/2" Type E full port series.
• Does this include the "K" dimension for stem setting? Yes, proper stem length is critical for diaphragm positioning; this kit supports the standard assembly procedures required to reset the valve stroke correctly.
