ASCO 302-278 Rebuild Kit

The ASCO 302-278 Rebuild Kit is a comprehensive maintenance solution designed for the ASCO 8302 series 2-way hung diaphragm valves. This genuine OEM kit ensures peak performance and extends the service life of high-flow solenoid valves used in demanding HVACR systems and industrial fluid control applications. Constructed with high-grade NBR (Buna-N) elastomers and durable stainless steel internal components, the kit provides superior sealing and chemical resistance for water, air, and light oil services. Each component is precision-engineered to meet original factory specifications, facilitating a seamless solenoid valve repair process that restores bubble-tight shutoff and prevents costly downtime. By utilizing the ASCO 302-278 replacement parts, technicians can maintain system integrity, optimize pressure ratings, and ensure reliable fluid regulation in critical piping infrastructures. This kit is an essential inventory item for facility managers seeking to maintain industrial valve performance without the need for full valve replacement.

• OEM Precision: Engineered specifically for the ASCO 8302 Series to ensure exact fitment and reliable operation.
• Enhanced Durability: Features high-performance NBR diaphragms for excellent resilience against mechanical wear and fluid exposure.
• Cost-Effective Maintenance: Restores full functionality to existing valve bodies, eliminating the expense of complete valve assembly replacement.
• Optimized Flow Control: Ensures leak-free performance and consistent pressure regulation across various media.

How do I know if my ASCO valve needs a 302-278 rebuild kit?
Signs of wear include internal or external leakage, sluggish valve response, or failure to open/close completely. Using this kit restores the internal sealing surfaces and diaphragm integrity.

What media is this rebuild kit compatible with?
The Buna-N components in this kit are ideal for neutral fluids such as air, inert gas, water, and light oils within standard temperature ranges.

Is the solenoid coil included in this repair kit?
No, this kit contains the internal mechanical components such as the diaphragm, springs, and O-rings. If the electrical coil is failing, it must be purchased separately.
