Danfoss 034G3501 EXV
The Danfoss 034G3501 EXV is a high-capacity ETS 400 linear positioning electric expansion valve engineered for precise liquid injection in large-scale air conditioning and refrigeration systems. Designed with a balanced piston, this valve ensures bi-flow operation and provides manual or automated solenoid tight shut-off in both directions, eliminating the need for separate solenoid valves in many piping configurations. The unit features 2 1/8 inch ODF solder connections and an integrated AST stepper motor actuator with an M12 connection, providing a 100% duty cycle for modulating control. With a maximum working pressure of 493 psig (34 bar), the Danfoss ETS 400 is compatible with a wide range of refrigerants including R410A, R407C, R134a, and R404A. This stepper motor EXV requires a bipolar current or voltage driver, such as the Danfoss EKD 316 or EKE series controllers, to achieve its full travel range of 17.2 mm for optimal superheat management.
Key Benefits- Precise Superheat Control: The bipolar stepper motor provides high-resolution positioning for stable evaporator performance under varying load conditions.
- Integrated Sight Glass: Features a built-in sight glass with a moisture indicator to monitor refrigerant state and flow direction in real-time.
- System Efficiency: The pressure-balanced design allows for identical capacity in both flow directions, supporting heat pump and hot gas defrost cycles.
- Durability: Constructed with internal and external corrosion-resistant materials and an IP67 enclosure rating for demanding mechanical environments.
What controllers are compatible with the Danfoss 034G3501?
This valve is designed to work with Danfoss EKE 1A, 1B, 1C and EKD 316 superheat controllers. It can also be driven by third-party 12V DC bipolar drivers that support 100 mA RMS chopper current.
Can the ETS 400 be used in oil-free systems?
Standard ETS series valves rely on the presence of oil in the refrigerant for lubrication of the internal transmission. For applications using oil-free centrifugal compressors, specific oil-free variants or Danfoss Colibri valves should be utilized.
What is the maximum cable length for the actuator?
Using a Danfoss EKD 316 controller, the maximum cable length is generally up to 150 feet (50 meters). For longer runs or high EMC environments, a 10 mH filter like the Danfoss AKA 211 should be installed at the driver terminals.
