Description
The Danfoss 032U3693 is a 3/4″ normally closed (NC) EVSIS 20 series solenoid valve engineered for precise refrigerant flow control in commercial and industrial refrigeration applications. Danfoss solenoid valves are globally recognized for their robust construction, long service life, and dependable operation in demanding HVAC/R environments.
Product Overview
The EVSIS 20 solenoid valve operates on a normally closed principle, meaning the valve remains closed when de-energized and opens upon energization — a critical safety feature that prevents unintended refrigerant flow during power interruptions. The 3/4″ connection size makes it well-suited for medium-capacity refrigeration circuits, including liquid line, suction line, and hot gas bypass applications.
Key Features
- 3/4″ pipe connection for versatile installation compatibility
- Normally closed (NC) operation — valve closes automatically on power loss for added system safety
- EVSIS 20 series design optimized for refrigeration solenoid valve applications
- Danfoss-engineered internals for long-lasting, low-maintenance performance
- Suitable for use in commercial and industrial refrigeration systems
- Compatible with a wide range of common refrigerants
- Compact, rugged body construction for reliable field installation
Typical Applications
- Liquid line solenoid valve service in refrigeration circuits
- Suction line and hot gas bypass control
- Commercial refrigeration equipment and walk-in cooler/freezer systems
- Industrial process cooling and HVAC/R systems
