Ball Valve is a type of valve that uses a ball-shaped disc to control the flow of fluids or gases. It is a quarter turn valve that is used for on/off control without pressure drop. This type of valve has a simple design and is easy to operate and maintain. The ball valve is ideal for applications where tight shut-off is required.
Pressure Regulator is a device that automatically maintains a constant pressure in a pipeline or any other system that carries gas or liquid.
Expansion Valve is a device which is used in refrigeration and air conditioning systems to control the amount of refrigerant flow into the evaporator. It is a critical component in the refrigeration system, that allows for the expansion of the high-pressure refrigerant to a low-pressure, low-temperature refrigerant gas.

The expansion valve is installed at the entrance of the evaporator. Its function is to eject the high-temperature and high-pressure liquid refrigerant from the liquid storage dryer from the small hole of the expansion valve, reduce the pressure, expand the volume, and convert it into a mist refrigerant. It absorbs heat in the evaporator and becomes a gaseous refrigerant.
The main function of the expansion valve is to control the flow of refrigerant in the air conditioning or refrigeration system. The expansion valve is usually installed at the connection between the condenser and the rear equipment to adjust the amount of refrigerant entering the evaporator.
