Alco 806818 Thermostatic Expansion Valve – TX7-Z17 – R410A – 99.4 kW – MOP +14 °C

Alco 806818 Thermostatic Expansion Valve – TX7-Z17, R410A, 99.4 kW, MOP +14 °C

The Alco TX7-Z17 thermostatic expansion valve (item number 806818) is designed for high-capacity refrigeration and air-conditioning systems using the R410A refrigerant. It features a MOP (Maximum Operating Pressure) function that limits the suction pressure to an evaporation temperature of approx. +14 °C, thereby ensuring reliable and efficient control of the refrigerant flow.
