Expansion Valve Castel 2230/4E


In stock

Castel thermostatic expansion valves series 22 regulate the flow of refrigerant liquid into evaporators; the liquid injection is controlled by the refrigerant superheat.
The new Castel “22” series are designed to work with interchangeable orifice assembly, to provide flexibility in selection of capacities, and can be used in a wide range of applications as listed below:
  • Refrigeration systems display cases in supermarkets, freezer, ice cream and ice maker machines , transport refrigeration
  • air conditioning systems
  • heat pump systems
  • liquid chillers

Which use the following refrigerant fluds : R22,  R134A, R404A, R407C, R507 proper to the group II

Castel thermostatic expansion valves act as throttle device between the high pressure and the low pressure sides of refrigeration systems and ensure that the rate of refrigerant fl ow into the evaporator exactly matches the rate of evaporation of liquid refrigerant in the evaporator.
If the actual superheat is higher than the set point the valve feeds the evaporator with more liquid refrigerant, if the actual superheat is lower than the set point the valve decreases the fl ow of liquid refrigerant to the evaporator.
Thus the evaporator is fully utilized and no liquid refrigerant may reach the compressor.
