Danfoss 032L1103 Valve

The Danfoss 032L1103 is a high-capacity, servo-operated piston solenoid valve from the proven EVR series, specifically the EVR 32 model. Engineered for demanding industrial and commercial HVACR applications, this normally closed (NC) valve features a 1 5/8 inch ODF solder connection, making it a standard choice for large-scale liquid, suction, and hot gas lines. Constructed with a durable cast iron body, it supports a maximum working pressure (MWP) of 655 psig (45.2 bar) and is compatible with a wide array of fluorinated refrigerants including R22, R134a, R404A, R407C, and R410A. This specific SKU includes a manual stem, allowing technicians to manually override the valve during pressure testing or system service when the coil is de-energized. With a Kv value of 16.7 m³/h (Cv of 19.3 gal/min), the 032L1103 solenoid valve ensures optimal flow regulation and reliable shut-off in high-capacity refrigeration plants.

Key Benefits:

• Broad Refrigerant Compatibility: Suitable for modern HFC and HCFC refrigerants, including A2L options, ensuring versatile stock utilization.
• Integrated Manual Stem: Simplifies system commissioning and troubleshooting by allowing manual opening for evacuation or diagnostic purposes.
• High Operational Limits: Capable of handling media temperatures from -40°F to 221°F, withstanding up to 300°F during defrost cycles.
• Robust Piston Design: The servo-operated piston mechanism provides precise control in high-flow environments where diaphragm valves may underperform.
• Serviceability: Designed for rapid onsite maintenance; replacement seal kits and service kits are readily available to maintain peak performance.

Common Questions:

• What is the minimum pressure differential required for this valve? The EVR 32 requires a minimum opening differential pressure (minODP) of 2.9 psi (0.2 bar) to ensure the piston stays off the seat for full flow.
• Does this valve include a solenoid coil? No, Danfoss solenoids are typically sold as separate components. You must select a compatible 10W or 20W AC/DC coil (such as the Danfoss clip-on series) to complete the installation.
• Can I install this valve in any orientation? For optimal reliability, it is best practice to install the valve in a horizontal line with the coil facing upwards, though horizontal orientations are generally permitted.
