Overview of 98-41000 98-41420 98-41421 98-41422 Pneumatic cage guided control valve

98-41000 98-41420 98-41421 98-41422 Pneumatic cage guided control valve is composed of 41000 series sleeve valve and pneumatic diaphragm multi spring actuator. Pneumatic diaphragm multi spring actuator has the characteristics of small volume and light weight; 41000 series sleeve valve is inserted into the valve body cylindrical sleeve and guided by the sleeve. It can slide up and down freely. The valve core and sleeve wall are respectively provided with windows with specific flow characteristics. When the valve core moves up and down in the sleeve, the flow area of the sleeve window is changed to achieve the purpose of regulating the medium flow.

Working Principle of 98-41000 98-41420 98-41421 98-41422 Pneumatic cage guided 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. The regulating valve is divided into electric regulating valve, pneumatic regulating valve and hydraulic regulating valve
