Two-seater pneumatic valve adopts double number guide structure adjustment

two-seater regulating pneumatic valve adopts double number guide structure, with many spring action of mechanism. With compact structure, light weight, large, pneumatic valve, flow characteristic accurately, convenient tear open outfit. Widely used in the precise control of gas, liquid and steam medium parameters such as pressure, flow rate, temperature and liquid level in a given value. Especially suitable for the pressure difference is bigger, allow the leak is large and not very clean medium occasion. There are standard and bellows seal, jacket insulation, and other varieties. The nominal pressure level products are pneumatic valve body diameter range DN ~. - apply fluid temperature ℃ ~ + ℃ range class. Standards for the leakage Ⅲ level and Ⅳ level. Flow characteristic of linear or percentage. A variety of specifications to choose from. Adjust the pneumatic valve, used for regulating the flow of medium, pressure and liquid level. According to adjust the position signal, the automatic control of pneumatic valve opening, so as to achieve the adjustment of the medium flow rate, pressure and liquid level. Adjust the pneumatic valve consists of electric actuators or pneumatic actuators and regulating pneumatic valve in two parts. Adjustment is usually divided into direct single seat type and direct two-seater type two kinds, the latter has a large flow capacity, unbalanced and the characteristics of stable operation, so often especially suitable for large flow, little pressure drop and leakage. Pneumatic valve is a fluid conveying system in the control unit, a cut-off, regulation, guide, to prevent the reverse flow, voltage regulator, the leakage of the shunt or overflow, and other functions. Used for fluid flow control system of pneumatic valve, from the most simple as pneumatic valve to the extremely complex control system used in all kinds of pneumatic valves, its quite a wide varieties and specifications. Pneumatic valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow.
