Two-seat control valve with double-numbered guiding structure

The two-seat control valve adopts a double-numbered guiding structure and is equipped with a multi-spring recruiting mechanism. The utility model has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, convenient assembly and disassembly, and the like. Widely used in precise control of gas, liquid, steam and other media process parameters such as pressure, flow, temperature, liquid level maintained at a given value. It is especially suitable for medium applications where the pressure difference is large and the leakage is also large and not very clean.
There are various types such as standard type, bellows seal type and jacket insulation type. The product's nominal pressure rating has a valve body diameter range of DN25 to 400. Applicable fluid temperature has a variety of grades ranging from -250 °C to +560 °C. The leakage standards are Class III and Class IV. The flow characteristics are linear or percentage. A wide variety of specifications are available.
Regulating valve for regulating the flow, pressure and level of the media. According to the adjustment part signal, the opening of the valve is automatically controlled to achieve the adjustment of the medium flow, pressure and liquid level. The regulating valve is composed of an electric actuator or a pneumatic actuator and a regulating valve. Regulating valves are usually divided into two types: straight-through single-seat and straight-through two-seat. The latter has the characteristics of large flow capacity, unbalanced operation and stable operation, so it is usually suitable for occasions with large flow, high pressure drop and low leakage. The valve is a control component in the fluid delivery system, with functions such as cut-off, regulation, diversion, anti-backflow, regulation, shunt or overflow relief. Valves for fluid control systems range from the simplest shut-off valves to the wide variety of valves used in extremely complex self-control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media.
