ASCO 304-006 Rebuild Kit

The ASCO 304-006 Rebuild Kit is a critical maintenance solution designed for ASCO 8040H and 8040G series solenoid valves. Engineered to handle gas shutoff applications, this kit ensures the integrity of the valve seat and internal seals, preventing leakage in high-cycle commercial combustion systems. The 1/8" NPT construction is built to withstand rigorous pressure fluctuations common in HVAC fuel gas lines. Using genuine ASCO replacement parts maintains the original factory specifications of the 2-way normally closed valve, ensuring reliable pilot gas control and main line shutoff. Technicians should verify coil insulation and plunger travel during installation to ensure optimal flow characteristics. This kit includes the necessary diaphragm, springs, and O-rings to restore the pressure rating and response time of the valve body, facilitating safe and efficient burner operation without necessitating a full valve replacement.

• Optimized Pressure Handling: Restores the valve's ability to maintain a tight seal under standard gas line pressures.
• Precision Fitment: Components are machined to exact tolerances for ASCO 8040 series compatibility, reducing troubleshooting time.
• Material Durability: High-grade elastomers and stainless steel springs provide resistance to chemical degradation and mechanical fatigue.
• Operational Reliability: Minimizes the risk of solenoid humming or slow closing times by replacing worn internal moving parts.

Common Questions

How do I know if the ASCO 304-006 is the correct kit for my valve?
Confirm the model number on your valve nameplate. This kit is specifically for the 8040H and 8040G gas valves. Rebuild kits are series-specific to ensure internal orifice alignment and spring tension are correct for the seat size.

Can this kit be used for liquid service applications?
No, the ASCO 304-006 is specifically designed for fuel gas applications. Using these seals in liquid service may lead to premature failure due to material incompatibility with specific fluids.

What are the signs that a solenoid valve needs a rebuild?
Typical indicators include internal leakage (passing gas when closed), visible external leaks at the bonnet, or failure of the valve to open fully due to plunger or spring fatigue.
