Such valves are the terminals of automatic control systems and remote control systems that control the flow of liquids and gases.
It is specially designed for the use of control valve in the three-way control.
A three-way valve can divide the fluid into two rows of exportation (shunt), or the fluid is funnelled out of a row of exportation (confluence).
The three-way valve is generally used in heating system, ventilation system, air conditioning and other industrial branches.
It is widely used in oil, chemical, electricity, metallurgy, biopharmaceutical and other working conditions.
