ASCO 302-379 Rebuild Kit

The ASCO 302-379 Rebuild Kit is a comprehensive maintenance solution engineered for ASCO 8302 series solenoid valves. This kit provides the critical internal components required to restore factory-spec pressure containment and flow control in high-cycle HVAC solenoid valve repair applications. Designed for 2-way normally closed configurations, the assembly features a precision-machined solenoid plunger, a high-grade rebuild kit diaphragm, and stainless steel compression springs to ensure reliable pilot-operated valve performance. For contractors managing industrial fluid control, this kit prevents internal bypass and external leakage caused by seat erosion or elastomer degradation. Utilizing genuine ASCO valve parts ensures mechanical compatibility with the original valve body, maintaining the 1/4-inch to 3/8-inch NPT flow characteristics. Field installation of this solenoid maintenance kit restores fast-acting response times and mitigates the risk of unscheduled system downtime in critical commercial process cooling and heating loops.

Technical Benefits

• Precision-Engineered Elastomers: High-durability materials designed to withstand repeated cycling and maintain a bubble-tight seal.
• OEM Component Matching: Ensures exact tolerances for the ASCO 302-379, eliminating the performance drift common with aftermarket kits.
• Streamlined Installation: Comprehensive component set allows for a full internal overhaul during a single service call.
• Enhanced Flow Integrity: Restores the original Cv factor and pressure rating of the valve body.

Common Questions

What is included in the ASCO 302-379 rebuild kit?
This kit typically includes the plunger assembly, diaphragm, O-rings, and various springs required to refresh the internal mechanical operation of the valve.

Can this kit be used for 3-way or normally open valves?
No, the 302-379 is specifically designed for the 8302 series 2-way normally closed pilot-operated valves. Always verify your valve series prefix before installation.

Does this kit require specialized tools for installation?
Standard technician hand tools are sufficient; however, ensure the valve body is de-pressurized and surfaces are cleaned of debris before reassembly to ensure a proper seal.
