KVS
KVS
Application
KVS is a series of electrically operated suction modulating control
valves for AC transport and refrigeration applications.
Function
Accurate temperature or pressure control is obtained by modulat-
ing the refrigerant ow in the evaporator with a current or voltage
driver.
With an EKC 368 controller (current driver) and an AKS sensor
placed in the media to be controlled, an accuracy better than
± 0.5 K can be obtained.
The balanced design provides bi-ow operation as well as sole-
noid shut-o function in both ow directions at MOPD 33 bar
(478 psi).
Advantages
• Balanced port design.
• High resolution for precise control.
• Solenoid tight shut-o.
• Low power consumption.
• Corrosion resistant design external as well as internal.
