Danfoss 032L1105 Solenoid Valve

The Danfoss 032L1105 Solenoid Valve is a high-capacity, normally closed (NC) servo-operated valve engineered for demanding HVACR applications. Specifically designed as an EVR 32 solenoid valve, this unit features 1 3/8" ODF solder connections and is built with a rugged cast iron body to handle high-pressure environments up to 655 psig (45.2 bar). This part is the direct technical replacement for legacy models 042H1177 and 046636. When performing a changeout, technicians must verify voltage requirements and replace the coil to ensure system compatibility, as the valve is supplied without a coil. With a Kv value of 16.7 m3/h (Cv of 19.3 gpm) and a manual operation feature, it provides precise flow control in liquid, suction, and hot gas lines. Optimized for a broad range of fluorinated refrigerants—including R410A, R404A, and R134a—this valve maintains performance across a medium temperature range of -40°F to 221°F.

Key Benefits

• Direct Drop-In Replacement: Specifically replaces obsolete Danfoss 042H1177 and 046636 models, ensuring minimal piping modifications during retrofits.
• High Differential Pressure: Supports a maximum opening differential pressure (MOPD) of up to 38 bar with a 10W AC coil, suitable for high-pressure R410A systems.
• Versatile Refrigerant Compatibility: Rated for use with HCFC, HFC, and R290 (for specific versions), compatible with POE, PAG, and mineral oils.
• Integrated Manual Stem: Features a manual override for system testing and emergency operation without electrical power.
• Serviceable Design: The EVR 32 series allows for top-entry maintenance, reducing downtime during seal or piston inspections.

Common Questions

Is the coil included with the 032L1105?
No, this is a "valve body only" configuration. You must select and install a compatible Danfoss junction box or conduit coil separately, ensuring the voltage matches your control circuit.

Can this valve be used in a suction line?
Yes, the servo-piston design of the EVR 32 is suitable for liquid, suction, and hot gas lines, provided the minimum pressure drop requirements are met for the valve to open.

What is the proper orientation for installation?
The valve must be installed with the coil in an upright position (no more than 90 degrees from vertical) and the flow following the arrow on the valve body.
