ASCO 304-354-V Rebuild Kit

The ASCO 304-354-V Rebuild Kit is a specialized service solution designed for the maintenance and repair of ASCO 2-way solenoid valves within high-temperature or chemically demanding HVACR environments. This kit features Viton (FKM) elastomers, providing superior thermal stability and chemical resistance compared to standard nitrile components. By replacing worn internal components with this kit, technicians can restore optimal valve seat integrity and prevent refrigerant leaks or pressure drops in critical lines. The package includes a precision-engineered diaphragm assembly, O-rings, and high-tensile stainless steel springs to ensure consistent mechanical cycling under heavy load. Utilizing an ASCO valve repair kit with Viton seals is essential for systems handling steam, corrosive fluids, or high-ambient temperatures where standard rubber would degrade. This kit ensures your solenoid valve maintenance meets factory specifications, maintaining system pressure and preventing solenoid coil overheating caused by internal friction or debris buildup.

Key Technical Benefits:

• High-Temperature Viton Seals: Engineered for FKM chemical resistance to handle aggressive media and elevated fluid temperatures without hardening.
• Drop-in Compatibility: Precision-fit components designed specifically for the ASCO 304-354 series, eliminating the need for field modifications.
• Enhanced Sealing Integrity: Restores the valve to its original bubble-tight shutoff rating, reducing system downtime and gas loss.
• Durable Internal Components: Includes industrial-grade springs and discs to withstand high-frequency cycling in commercial HVACR systems.

Common Questions:

When should I choose the Viton version over the standard ASCO rebuild kit?
Use the ASCO 304-354-V when the application involves high temperatures (up to 250°F) or specific chemicals and oils that cause standard Buna-N seals to swell or fail.

Does this kit include the replacement solenoid coil?
No, this is a mechanical rebuild kit focused on the internal wetted parts like the diaphragm and gaskets. If the coil has failed electrically, it must be ordered separately.

Will this kit work for all ASCO 304-354 series valves?
Yes, it is the standard OEM replacement kit for that specific series, but always verify the "V" suffix on your valve body to ensure Viton is the required elastomer for your specific fluid medium.
