Danfoss 032L1291 Valve

The Danfoss 032L1291 is a high-performance EVR 10 Normally Open (NO) solenoid valve designed for liquid, suction, and hot gas lines in commercial refrigeration and air conditioning systems. Engineered with a 1/2" ODF solder connection, this valve ensures a hermetic seal and reduced leak potential within the refrigerant circuit. It is compatible with a wide range of fluorinated refrigerants, including R22, R134a, R404A, R407C, and R410A, making it a versatile component for service and retrofits. The direct-operated or servo-operated design (depending on specific pressure differential requirements) provides reliable opening and closing cycles even under high-pressure conditions. Contractors select the EVR series for its robust build quality and its MOPD capabilities up to 38 bar. This 1/2" solenoid valve is typically paired with 10W or 12W AC or DC coils to maintain steady state operation in demanding HVACR environments.

• Broad Refrigerant Compatibility: Optimized for use with high-pressure refrigerants like R410A and traditional HFCs.
• Normally Open (NO) Operation: Ensures the circuit remains open during power loss, critical for specific fail-safe system designs.
• Solder Connections: The 1/2 inch ODF copper extensions allow for standard brazing techniques without disassembling the valve body.
• Extended Service Life: Built to withstand commercial duty cycles with minimal mechanical wear on the internal piston and seat.

Common Installation Questions

Does this valve require a specific coil type?
Yes, the Danfoss EVR 10 uses the clip-on coil system. Ensure you match the voltage and wattage to your control circuit; typically, a 10W coil is sufficient for standard applications.

Can the 032L1291 be installed in any orientation?
It is recommended to install the valve with the coil in a vertical position (upward) to prevent debris accumulation and ensure optimal armature movement, though horizontal orientation is permissible in certain configurations.

What is the maximum operating pressure for this unit?
The valve body is rated for a Maximum Working Pressure (MWP) of 653 psig (45 bar), making it suitable for high-pressure R410A systems.
