Danfoss 032U3693 Solenoid Valve

The Danfoss 032U3693 Solenoid Valve is a high-performance EVSI 20 series component designed specifically for industrial applications requiring reliable liquid or suction line control. This Normally Closed (NC) valve features a 3/4 inch NPT connection and utilizes a servo-operated piston design to manage high pressure differentials in demanding HVACR environments. Engineered for use with neutral media, the 032U3693 is built with a robust brass body and specialized internal seating that ensures tight shut-off and prevents seat leakage under vibration. It is compatible with a wide range of standard Danfoss clip-on AC and DC coils, allowing for field-service flexibility when matching voltage requirements. As a Danfoss industrial solenoid valve, this unit maintains a high degree of durability against media impurities, ensuring the solenoid valve 3/4 inch sizing provides optimal flow capacity (Cv value) for commercial-grade piping systems.

• Internal Pilot Design: Optimized for high-pressure systems, requiring a minimum differential pressure for reliable opening and closing cycles.
• Durable Brass Construction: Resistant to corrosion and mechanical stress, maintaining structural integrity in varied mechanical room conditions.
• Standardized Coil Compatibility: Utilizes the Danfoss clip-on system for rapid electrical installation and easy maintenance without system depressurization.
• Debris Resistance: Features an internal design that mitigates the risk of clogging from pipe scale or refrigerant oil buildup.

Common Installation & Application Questions

What is the minimum pressure differential required for this valve to function?
The EVSI 20 is a servo-operated valve, meaning it utilizes system pressure to actuate. It typically requires a minimum differential pressure of 0.05 bar (approx. 0.73 psi) to ensure the piston seats and unseats correctly.

Can the 032U3693 be installed in any orientation?
For optimal longevity and to prevents sludge buildup around the armature, it is recommended to install the valve with the coil oriented vertically upwards. Horizontal orientation is permissible, but should be avoided if the system has high particulate levels.

Standard Coils for Danfoss 032U3693:
This valve body is sold separately from the coil. It is designed to work with the 10W or 12W clip-on coil series to meet specific site voltage needs, whether 24V, 110V, or 230V applications.
