Spence 07-07749-00 Repair Kit

The Spence 07-07749-00 Repair Kit is a comprehensive rebuild solution designed specifically for 1-inch Type E Full Port Main Valves. As a critical component in steam pressure regulation, this kit allows for full in-line maintenance without the need to remove the cast iron valve body from the piping. This 1" E-Valve repair kit features high-integrity stainless steel diaphragms and a precision-engineered seat ring to restore tight shut-off and stable pilot-operated control. Utilizing an OEM Spence 07-07749-00 kit ensures that the flow coefficient (Cv) and pressure-temperature ratings of your steam pressure regulator remain within factory specifications. The inclusion of a new stem, disc, and high-pressure spring addresses common wear points that lead to erratic delivery pressure or internal hunting. For contractors managing industrial steam systems, this kit provides the essential main valve parts required to maintain the packless construction and frictionless travel that the Type E series is known for.

• Complete Internal Restoration: Includes essential components like stainless steel diaphragms, stem, disc, and seat ring for a total rebuild.
• In-Line Serviceability: Designed for rapid valve maintenance, significantly reducing system downtime during scheduled steam outages.
• Optimized Performance: Restores the original pressure regulation accuracy and sensitivity of the Spence Type E main valve.
