Trane VAL1829 Solenoid Valve

The Trane VAL1829 is a high-performance 2-way normally closed solenoid valve designed for precise refrigerant flow control in commercial HVAC and refrigeration systems. Featuring a 7/8" ODF solder connection, this valve ensures a leak-proof, sweat-in installation compatible with standard piping sizes. Engineered for Trane chiller systems and rooftop units, the VAL1829 manages liquid, suction, or hot gas discharge lines effectively. Its pilot-operated diaphragm design allows for operation across high-pressure differentials, making it a reliable component for R-22 and R-410A refrigerant applications. The body is constructed from durable forged brass to withstand high working pressures and prevent thermal fatigue during rapid cycling. Technicians can rely on this refrigeration solenoid valve for tight shut-off performance, preventing migration during the off-cycle and ensuring system efficiency. Use this HVAC replacement part when maintaining Trane liquid line solenoid assemblies to restore original equipment manufacturer (OEM) specifications to the refrigeration circuit.

• Optimized Flow Control: The 7/8 inch ODF connections provide high-flow capacity with minimal pressure drop across the valve seat.
• Broad Compatibility: Designed specifically for Trane HVAC systems, ensuring seamless integration with existing control boards and coil voltages.
• Durable Construction: Heavy-duty brass body prevents corrosion and handles the high-pressure demands of modern refrigerant flow control.
• Normally Closed Logic: Provides fail-safe operation by automatically closing the refrigerant line upon loss of power to the solenoid coil.

What is the proper orientation for installing the Trane VAL1829?
Directional flow is critical for proper operation. Ensure the arrow on the valve body aligns with the refrigerant flow path, and install the valve with the solenoid coil upright to prevent debris accumulation in the plunger tube.

Does this valve include the solenoid coil?
The Trane VAL1829 is the valve body assembly. Technicians should verify the required voltage (typically 24V or 120V) and ensure the existing or replacement coil is compatible with this specific valve stem.

Can this solenoid valve be used on suction lines?
Yes, the pilot-operated design allows for use in suction line applications, provided the minimum pressure differential required for the diaphragm to lift is maintained during operation.
