Danfoss 067N3157 Expansion Valve
The Danfoss 067N3157 (Type TGEL 10) is an externally equalized thermal expansion valve engineered for high-capacity R410A refrigeration and air conditioning systems. This straight body TXV features a 5/8" ODF inlet and 7/8" ODF outlet with a 60-inch capillary tube, providing flexible bulb placement for accurate superheat control. Designed with a 13-ton cooling capacity and a number 11 orifice, this valve manages refrigerant flow efficiently across a wide range of evaporator loads. The integrated MOP (Maximum Operating Pressure) of 667 PSI protects the compressor motor against overload during start-up or high-pressure surges. Built for reliability in demanding commercial environments, the stainless steel power element and laser-welded construction ensure long-term setting stability and resistance to corrosion in high-vibration HVACR cycles.
Key Technical Benefits
- Precision Superheat Control: The thermal expansion valve maintains optimal evaporator efficiency by adjusting flow based on load demand.
- System Protection: A 667 PSI MOP setting prevents suction pressure from exceeding safe limits, protecting the compressor.
- Durable Construction: Features a stainless steel bulb and capillary tube for superior heat transfer and mechanical strength.
- External Equalization: Compensates for pressure drops across the evaporator, ensuring accurate refrigerant metering in large-scale R410A systems.
- Installation Ready: Includes a factory-installed number 11 orifice and a dedicated bulb strap for secure mounting.
Common Questions
What is the purpose of the 667 PSI MOP on this valve?
The Maximum Operating Pressure (MOP) feature limits the suction pressure to 667 PSI, which prevents the compressor motor from overloading during high-load periods or after a defrost cycle.
Can the TGEL 10 be used with refrigerants other than R410A?
No, the Danfoss 067N3157 is specifically calibrated for the pressure-temperature characteristics of R410A. Use with other refrigerants will result in improper superheat and potential system damage.
Why is external equalization necessary for a 13-ton capacity valve?
In high-capacity systems, the pressure drop through the evaporator is often significant. External equalization allows the valve to sense the actual pressure at the evaporator outlet, ensuring precise refrigerant flow control.
