Thermostatic expansion valve Danfoss TUBE, R290 068U3704

Thermostatic expansion valve TUBE Danfoss R290 068U3704

Thermostatic expansion valve works based on the balance of the system of forces caused by the pressure in the sensor, the evaporation pressure and the spring tension. The pressure in the sensor exerts pressure on one side of the membrane, and the evaporation pressure together with the spring on the other. The change in superheating is achieved by changing the spring tension.

Temperature Range [°C]: -40 - 10, Nozzle Efficiency [kW]: 1.46, Nozzle Efficiency [TR]: 0.42, Pressure Equalization: External Equalization

Application:

• · traditional refrigeration systems
• · mobile refrigeration systems
• · air conditioning devices
• · water coolers
