Overview of  98-21225 97-21215 98-21215 Single seated control valve

98-21225 97-21215 98-21215 Single seated control valve is composed of 21000 series single seat valve imported by American maysonland company and self-developed pneumatic diaphragm multi spring actuator. It not only has the characteristics of small volume and light weight of the actuator, but also has the characteristics of 21000 series single seat valve, such as wide application range, good stability and small leakage. It is very suitable for automatic control of industrial processes such as petroleum, chemical industry and metallurgy. Pneumatic control valve is one of the products. Single seat regulating valve is the final control element in the field of industrial automation process control, which changes the process parameters such as medium flow, pressure, temperature and liquid level by receiving the control signal output by the regulating control unit and with the help of power operation.

Working Principle of  98-21225 97-21215 98-21215 Single seated control valve

The regulating valve is composed of electric actuator or pneumatic actuator and regulating valve. The regulating valve is usually divided into straight through single seat regulating valve and straight through double seat regulating valve. The latter has the characteristics of large flow capacity, small imbalance and stable operation, so it is usually especially suitable for occasions with large flow, high pressure drop and less leakage .The regulating valve is used to regulate the flow, pressure and liquid level of the medium. The opening of the valve is automatically controlled according to the signal of the regulating part, so as to achieve the regulation of medium flow, pressure  and liquid level.
