Alco expansion valve R407C TX7-N16m MOP+17 22x28mm 806874

ALCO Thermo^® TX7 expansion valves have been developed for the specific requirements of air conditioning applications, cold water units, refrigerated transportation, heat pumps, industrial cooling and other refrigeration applications. Wherever a compact hermetic expansion valve is required, the TX7 with its stable and precise control can be used anywhere within the operating range. The laser-welded valve tops made from stainless steel with a special membrane offer a long service life when used with high-pressures and an external pressure equalisation connection (even in reverse flow direction during operation).

• Monoblock hermetic design with solder connections

• 7 valve sizes up to 180 kW (R410A)

• Maximum operating pressure: 46 bar

• Temperature range for medium: -25 ... +70 °C

• Medium compatibility R410A, R134a, R407C, R32, R450A, R513A

• Bi-flow applications

  • Balanced port structure in normal and reverse flow direction prevents disruptive influences resulting from condensing pressure

  • Optimal static superheating in both flow directions

  • Performance of the valve in normal and reverse flow directions corresponding to the power of the heat pump devices in cooling and heating operation

• Valve top with 65 mm diameter for low partial low control (20--25%) with stable superheating

• Can be used in systems with Digital Scroll, variable screw compressors and frequency-controlled compressors

• Sliding superheating in reverse flow direction in order to ensure compressor efficiency in air-cooled water cold water units when operating in heating mode in low ambient conditions

• Capillary pipe length of 1.5 m

• No CE mark according to Pressure Equipment Directive 2014/68/EU
