Alco 806855 Thermostatic Expansion Valve – TX7-M17M – R134A – 56 kW – MOP +14 °C

Alco 806855 Thermostatic Expansion Valve – TX7-M17M, R134a, 56 kW, MOP +14 °C

The Alco TX7-M17M thermostatic expansion valve (item number 806855) is designed for use in high-capacity refrigeration and air-conditioning systems using the refrigerant R134a. It ensures precise control of the refrigerant flow based on superheat and features a MOP (Maximum Operating Pressure) function that limits the suction pressure to an evaporation temperature of approximately +14 °C.

Advantages and benefits

• Optimal regulation of the refrigerant flow for efficient cooling performance and stable superheat.
• High rated capacity of 56.0 kW – ideal for medium to large refrigeration and air-conditioning systems using R134a.
• MOP function (+14 °C) limits the maximum suction pressure, thereby protecting the compressor, particularly during start-up or after defrost cycles.
• Easy integration into pipework systems thanks to standardised 22 × 28 mm brazed connections and a 6 mm equaliser connection.
