Thermostatic Expansion Valves

Thermostatic Expansion Valves

 

Thermostatic expansion valves regulate the
injection of refrigerant liquid into evaporators.
Injection is controlled by the refrigerant superheat.
Therefore the valves are especially suitable for		 liquid injection in ”dry“ evaporators where the
superheat at the evaporator outlet is proportional
to the evaporator load
 

 

Large temperature range
Equally applicable to freezing, refrigeration
and air conditioning applications.
Interchangeable orifice assembly
– easier stocking
– easy capacity matching
– better service.
Rated capacities from 0.5 to 15.5 kW
(0.15 to 4.5 TR) for R22.
Can be supplied with MOP
(Max. Operating Pressure)
Protects the compressor motor against
excessive evaporating pressure during normal
operation.
Stainless steel bulb
Fast and easy to install.
Good temperature transfer from pipe to bulb.
Valves for special temperature ranges can be
supplied
