- Inlet Connection: 1-1/8″ ODF (straight body)
- Outlet Connection: 1-3/8″ ODF (straight body)
- Capillary Tube Length: 60 inches for flexible bulb placement
- Equalization Type: Externally equalized for accurate pressure sensing across the evaporator
- Orifice: Number 40
- Includes bulb strap for secure thermal bulb mounting
- Valve Type: TGEL 40 series
Product Overview
The externally equalized design of the Danfoss 067N3019 makes it ideal for evaporators with significant pressure drop, ensuring the valve responds to true evaporator outlet conditions rather than inlet pressure alone. The 60″ capillary tube provides ample reach for bulb placement in large or complex evaporator configurations. The included bulb strap ensures a secure, thermally conductive connection to the suction line for accurate superheat sensing.
With a high MOP rating of 667 PSI and compatibility with R410A, this valve is built to handle the elevated pressures characteristic of modern high-efficiency systems. The straight body configuration with 1-1/8″ ODF inlet and 1-3/8″ ODF outlet connections simplifies installation in commercial systems.
Applications
- Large commercial air conditioning systems
- R410A refrigeration systems up to 46 tons
- Evaporators with high internal pressure drop
- Systems requiring precise superheat control at high operating pressures
