Electronic Expansion Valve for Air Conditioning System



Production Description:

Electronic expansion valves are designed for usage in air conditioning and refrigeration systems or in heat pumps. The valve supports automatic adjustment of refrigerant flow rate and makes the system work under optimized conditions for the purpose of fast cooling or heating, precise temperature control and energy saving. The valve can also be used e.g. for suction line pressure controls. These valves provide bidirectional operation to control the refrigerant flow rate in heating or cooling mode.

Plastic Masterbatch

Masterbatches are mainly used on plastics. The color masterbatch is composed of three basic elements: pigments or dyes, carriers and additives. It is an aggregate obtained by uniformly loading a large amount of pigment into the Resin. It can be called Pigment Concentration. The tinting strength is higher than the pigment itself. Mixing a small amount of color masterbatch and uncolored resin during processing can achieve a colored resin or product with a designed pigment concentration.
