Trane COL5758 Solenoid Coil 318172-701 which drops the vacuum pressureThe Trane COL5758 Solenoid Coil is a critical HVAC 24V replacement coil engineered for precise refrigerant flow control within compatible Trane and American Standard cooling systems. Designed for integration with specific liquid line solenoid valves, this low voltage coil ensures reliable electromagnetic force to actuate the valve plunger during demanding cycles. Its robust encapsulated design resists moisture and thermal stress, preventing premature
