ASCO 312-702 Rebuild Kit

The ASCO 312-702 Rebuild Kit is a critical maintenance solution designed for the 8220 Series RedHat II solenoid valves, specifically optimized for high-temperature steam and hot water applications. As a veteran-grade repair kit, it includes all OEM internal wear parts required to restore factory-spec pressure vessel integrity and flow control. This kit features a piston-disc assembly, core tube, springs, and high-grade O-rings and gaskets. Utilizing a solenoid valve repair kit like the 312-702 ensures that your 2-way internal pilot operated valves maintain their bubble-tight shutoff capabilities without the need for full body replacement. For contractors servicing 3UL32 or 8220G023 models, this kit provides the necessary ASCO valve replacement parts to mitigate seat leakage and coil humming. Field reliability is improved by replacing the core guide and diaphragm components simultaneously, ensuring the valve meets original timing and differential pressure requirements in demanding HVACR environments.

• Direct OEM Compatibility: Specifically engineered for ASCO 8220 Series and RedHat II steam valves to ensure precise mechanical fit.
• Comprehensive Component Count: Includes core tube assembly, springs, gaskets, and seals to address all common failure points in one service interval.
• Steam-Rated Performance: Materials are selected to withstand the thermal expansion and corrosive nature of industrial steam and hot air cycles.
• System Longevity: Prevents expensive downtime by rebuilding the internal pilot mechanism rather than replacing entire valve manifolds.

• What valves are compatible with the ASCO 312-702 kit? This kit is primarily used for the 8220 Series, including specific models like the 8220G023 and 3UL32. Always verify the rebuild kit number against the valve nameplate.
• Does this kit include the solenoid coil? No, this is a mechanical rebuild kit containing the internal moving parts and seals. If the coil is burnt out, it must be purchased separately.
• How do I know if the valve needs a rebuild or a total replacement? If the valve body shows no signs of erosion or cracking but the valve fails to open/close or exhibits external leakage around the bonnet, a 312-702 rebuild kit is the standard solution.
