Danfoss 034G1705 EXV
The Danfoss 034G1705 EXV is a high-performance ETS 50 electric expansion valve engineered for precise refrigerant displacement in demanding HVACR systems. Designed with a 7/8" x 1 1/8" ODF solder connection, this unit is built for high-capacity liquid injection in both air conditioning and refrigeration evaporators. Its balanced port design allows for bi-flow operation, providing consistent performance and a solenoid-tight shut-off in both directions. This bi-polar stepper motor valve ensures extremely accurate flow regulation, making it essential for systems requiring tight superheat control. Compatible with Danfoss EKE controllers and high-authority R410A, R407C, R404A, and R134a refrigerants, it operates effectively within a wide temperature range from -40°F to 149°F. The 034G1705 features a built-in sight glass with a moisture indicator, allowing for real-time fluid inspection. For contractors, the bi-metal stainless steel/copper connections simplify the installation process by enabling waterless brazing, significantly reducing labor time on the job site.
Key Benefits for Technicians:- Precise Superheat Control: The bipolar motor technology provides high-resolution positioning for optimal energy efficiency and evaporator utilization.
- Bi-Flow Functionality: Fully balanced design ensures the Danfoss ETS 50 performs reliably in heat pump applications and systems with reversible cycles.
- Simplified Installation: Bi-metal connectors allow for direct soldering 7/8 inch inlet and 1 1/8 inch outlet connections without the need for wet cloths or heat sinks.
- Integrated Diagnostics: Includes a factory-installed moisture indicator sight glass to monitor refrigerant quality and state without additional fittings.
- Robust Environmental Protection: Rated for IP67, ensuring the actuator and internal components are protected against dust and moisture ingress in harsh mechanical rooms.
Which controllers are compatible with the Danfoss 034G1705?
This valve is designed to work seamlessly with Danfoss EKE 1A, 1B, and 1C series controllers, as well as the EKD 316 and MCX series. It can also be integrated with third-party drivers that support bipolar stepper motors with a 52 Ohm phase resistance.
Can this EXV be used with CO2 (R744) systems?
The standard Danfoss 034G1705 is rated for a maximum working pressure of 660 psig (45.5 bar). While compatible with many common HFCs and HCFCs, specific high-pressure versions are typically required for transcritical CO2 applications.
Does the valve require a separate solenoid for shut-off?
No, the ETS 50 series is designed to provide solenoid-tight shut-off in both flow directions, eliminating the need for an additional solenoid valve in the liquid line for system holding.
