Carel expansion valve body for E2V-Z E2VATT09Z0

The E2V-Z has been developed for applications that for reasons of maintenance require removeable valves. The integrated filter allows for perfect cleaning, even after the system has been started up. The newly integrated valve connection protects the moving parts from impacts. The stepper motor technology ensures a constant and perfect flow of refrigerant in the evaporator. This increases system efficiency and control stability. Combined with energy saving algorithms such as suction pressure regulation, condenser pressure regulation and smooth line regulation, the controller can work with an amount of refrigerant in the evaporator that is perfectly adjusted to the operating conditions. The ability to separate the valve body, actuator and stator makes installation simple. 1. Only the valve body needs soldering, thus avoiding any excessive heat causing damage to other parts. 2. The choice and installation of the valve takes place during the manufacturing process. 3. The appropriate stator and connection cable are combined when wiring.

The expansion valves are available in various sizes and can be combined with expansion valve bodies and expansion valve coils from the E2V-Z series.
