ASCO 43005590 Coil

The ASCO 43005590 solenoid coil is a critical replacement component for 8210 series pilot-operated valves and 8262 series direct-acting valves. Engineered for 240V 60Hz AC applications, this Class F insulation coil is designed to withstand continuous duty cycles in high-temperature environments common in commercial HVACR and industrial fluid control. This epoxy-encapsulated solenoid valve coil provides superior thermal dissipation and moisture resistance, ensuring reliable electromagnetic actuation of the valve plunger. As a standard ASCO Red Hat compatible part, it features 18-inch lead wire connections for straightforward integration into existing control circuits. When replacing a failed coil, verify the voltage rating and series compatibility to prevent premature burnout or insufficient opening force under pressure.

Key Benefits

• Continuous Duty Rated: Constructed with Class F high-temperature insulation to prevent dielectric breakdown during prolonged operation.
• Exact OEM Fit: Designed specifically for ASCO 8210 and 8262 series valves, ensuring proper magnetic flux coupling.
• Environmental Protection: The epoxy-molded construction protects internal windings against dust, vibration, and moisture.
• Standardized Wiring: Includes color-coded lead wires for fast terminal connections in 240VAC control panels.

Common Questions

How do I verify if this coil fits my ASCO valve?
Check the nameplate on your existing valve body. The ASCO 43005590 is used primarily with 1/2" to 1" NPT valves in the 8210 and 8262 series that require a 240/60 voltage configuration.

Can I use this 240V coil on a 208V circuit?
While some coils are dual-rated, using a dedicated 240V 60Hz coil on 208V may result in reduced magnetic force, potentially preventing the valve from opening against high differential pressures.

What are the symptoms of a failing solenoid coil?
Look for signs of overheating, visible swelling of the epoxy, or an open circuit when testing for coil resistance with an ohmmeter.
