ASCO 186-270 Rebuild Kit

The ASCO 186-270 Rebuild Kit is a comprehensive field-maintenance solution designed for ASCO 8210 Series solenoid valves. This genuine OEM kit ensures pressurized system integrity by replacing critical internal components susceptible to wear from high cycle rates and fluid contaminants. Engineered for high-flow 2-way normally closed valves, the kit features a precision-machined diaphragm assembly, stainless steel solenoid core, and high-performance return springs. Utilizing these ASCO valve repair parts restores the original factory specifications for bubble-tight shutoff and optimal pressure ratings. Proper installation of the 186-270 rebuild kit eliminates common failure points such as internal leakage, slow response times, and coil-hum resulting from worn core assemblies. Technical compatibility includes specific 3/4-inch and 1-inch NPT valve bodies, ensuring a precise mechanical fit for industrial and commercial fluid control applications where downtime is not an option.

Key Technical Benefits

• Factory-Spec Sealing: Includes a reinforced diaphragm designed for consistent valve seat engagement.
• Enhanced Durability: Stainless steel internal components resist corrosion and mineral buildup.
• Optimized Flow Control: Restores solenoid valve responsiveness to prevent water hammer and pressure drops.
• Complete Component Match: Provides all necessary O-rings, gaskets, and springs for a full internal overhaul.

Common Questions

How do I know if the ASCO 186-270 is the correct kit for my valve?
Confirm the valve catalog number on your nameplate. This kit is specifically engineered for certain 8210 series pilot-operated valves. Cross-referencing the rebuild kit number ensures proper orifice alignment and spring tension.

Does this kit include the solenoid coil?
No, this is a mechanical ASCO repair kit. If your coil is burnt out or shows signs of insulation failure, the coil must be sourced separately based on voltage requirements.

Can I use this kit for high-temperature steam applications?
This kit is designed for standard fluid and gas service. For high-temperature or steam-specific 8210 models, ensure the elastomer material in the kit matches your specific media and temperature range.
