ASCO 224845-120 Coil

The ASCO 224845-120 Coil is a precision-engineered 120V/60Hz solenoid replacement coil designed for high-cycle industrial and HVACR applications. As a critical component for ASCO RedHat solenoid valves, this coil converts electrical energy into the mechanical force required to actuate the valve plunger. Engineered for continuous duty, the 224845-120 provides reliable electromagnetic actuation, ensuring consistent flow control of air, gas, water, or light oil. This genuine ASCO replacement part features Class F or Class H insulation to withstand high ambient temperatures, typically rated for operation between -5°F and 125°F. Professional contractors rely on this solenoid valve coil for its exact fit and inductive properties, which minimize inrush current issues and prevent premature coil burnout. When replacing a failed ASCO 224845-120, technicians should always verify coil resistance (typically around 210 Ohms) to ensure the system remains within factory specifications for 120VAC 60Hz circuits. This part is essential for maintaining the pressure ratings and response times of your existing valve body.

• Direct OEM Replacement: Guaranteed compatibility with specific ASCO RedHat valve series, maintaining original solenoid valve performance specs.
• Thermal Resilience: High-grade insulation protects the 120V solenoid coil from the heat generated during the holding current phase.
• Efficient Actuation: Precisely wound copper inductor ensures the magnetic field is strong enough to seat the plunger even in high-differential pressure environments.
• Durable Encapsulation: Robust epoxy or molded construction protects the internal solenoid windings from moisture and industrial contaminants.

What causes an ASCO 224845-120 coil to burn out?
Coil failure is often caused by a mechanical obstruction in the valve body. If the plunger cannot seat fully, the coil remains in a high inrush current state, leading to thermal catastrophe. Always inspect the valve stem for scale or debris during replacement.

Can I use this 120V/60Hz coil on a 50Hz system?
Using a 60Hz coil on a 50Hz supply will typically result in higher operating temperatures and potential humming/buzzing. For optimal HVACR system reliability, match the frequency exactly to the power source.

How do I test if my ASCO solenoid coil is defective?
Perform a continuity and resistance check using a multimeter. An "Open" (OL) reading indicates a broken winding, while a reading significantly outside the 210 Ohm range (typically +/- 5%) suggests internal shoring.
