Valve - control valve

Regulating valve

The regulating valve is used to adjust the flow, pressure and liquid level of medium. According to the signal of the regulating position, the opening of the valve is automatically controlled, so as to adjust the medium flow, pressure and liquid level. The control valve is divided into electric control valve, pneumatic control valve and hydraulic control valve.

The regulating valve is composed of electric actuator or pneumatic actuator and regulating valve. The control 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 large flow, high pressure drop and less leakage.

Regulating valve can be divided into straight stroke and angular stroke according to stroke characteristics. Straight stroke includes: single seat valve, double seat valve, sleeve valve, cage valve, angle valve, three-way valve and diaphragm valve; angular travel includes butterfly valve, ball valve, eccentric rotary valve and full-function ultra light control valve. Genius valve

The control valve can be divided into manual control valve, pneumatic control valve, electric control valve and hydraulic control valve according to the driving mode, that is, the pneumatic control valve with compressed air as the power source, the electric control valve with electricity as the power source, and the hydraulic control valve driven by the pressure of liquid medium (such as oil);

According to the regulation form, it can be divided into: regulation type, cut-off type and adjustment cut-off type;

According to the flow characteristics can be divided into: linear, logarithmic (percentage), parabola, fast opening.
