Danfoss 067N3156 Expansion Valve

The Danfoss 067N3156 (Type TGEL 10) is a high-capacity thermostatic expansion valve (TXV) engineered for precision refrigerant metering in 9-ton AC systems. Designed with a balanced port to handle varying head pressures, this externally equalized valve ensures optimized evaporator efficiency and prevents liquid slugging in R410A refrigeration and R32 applications. The straight-body configuration features 5/8" ODF x 7/8" ODF copper connections for reliable solder joints and a 60-inch capillary tube for flexible bulb placement. This unit includes a number 8 orifice and a dedicated bulb strap to ensure accurate thermal contact. With a Maximum Operating Pressure (MOP 667 PSI) and a robust brass body, the TGEL 10 is the go-to HVAC replacement expansion valve for contractors requiring stable superheat control across a wide range of operating conditions. Its bi-flow capability and stainless steel power element make it a durable solution for demanding commercial and residential environments.

• Precise Superheat Control: The thermal expansion valve features a laser-welded stainless steel element for consistent performance and long-term reliability.
• Balanced Port Design: Minimizes the influence of condensing pressure fluctuations, ensuring stable operation even in varying ambient conditions.
• R410A and R32 Compatibility: Specifically optimized for high-pressure refrigerants with a 9-ton capacity rating (32 kW).
• Easy Installation: The 5/8 x 7/8 ODF solder connections and inclusive bulb strap streamline the replacement process in the field.
• Enhanced Safety: Built-in MOP (Maximum Operating Pressure) protection prevents compressor overload during start-up or high-load scenarios.

• Is the Danfoss 067N3156 suitable for bi-flow applications? Yes, the TGE series design allows for bi-flow operation, making it suitable for heat pump applications.
• Does this valve include the orifice? Yes, this specific model (067N3156) is equipped with a fixed number 8 orifice.
• What is the purpose of the external equalization? The 1/4" ODF external equalization line ensures the valve reacts to the actual pressure at the evaporator outlet, compensating for any pressure drop across the distributor.
