Spence 08-08115-00 Repair Kit

The Spence 08-08115-00 A-Pilot Repair Kit is a comprehensive rebuild solution designed for service contractors maintaining Spence A-Series air-adjusted pilots. This kit is essential for restoring the pressure regulation accuracy of pilots used in conjunction with Spence Type E or Type C main valves. As a veteran-grade pilot valve rebuild kit, it includes critical internal components such as the stainless steel valve stem, seat ring, valve disc, and high-durability SST diaphragms. Professionals utilize this kit to address common wear patterns in steam pressure regulators, ensuring consistent delivery pressure even under varying inlet conditions. By replacing the internal steam screen and pusher plate assembly, technicians can eliminate hunting or erratic control issues typical of fouled pneumatic pilot systems. This kit is specifically engineered for cast iron pilot bodies and follows the Spence Engineering exacting tolerances for high-temperature steam and fluid control applications, facilitating a complete field overhaul without the need for total unit replacement.

• Optimized Pressure Stability: Restores factory-spec movement to the valve stem and pusher plate, preventing pressure drift in air-loaded pilots.
• High-Temperature Durability: Includes stainless steel diaphragms and discs designed to withstand the thermal stresses of continuous steam service.
• Reduced Maintenance Downtime: A complete all-in-one Spence regulator parts solution that eliminates the need to source individual gaskets or nuts during a pilot valve overhaul.
• Precision Seating: New seat rings and discs ensure tight shut-off, preventing "creep" in the delivery line when the system is under low-demand conditions.

• How do I know if my A-Pilot needs a rebuild? If you observe sluggish response to air loading changes or if the main valve fails to open/close fully, the internal diaphragms or the valve spring within the pilot are likely fatigued or fouled.
• Does this kit work for all A-Series pilots? This specific SKU is designed for the standard Type A air-adjusted pilot. For high-pressure variants like the A53 or A73, verify compatibility as spring rates and diaphragm counts may differ.
• Why is the steam screen included in the kit? The internal steam screen is a critical filter; scale buildup here is the #1 cause of pilot failure. Replacing it during every service interval is standard best practice for any HVACR technician.
