WCB CF8 Electric Straight Through Dual Seat Pressure Regulating Control Valve
Product introduction:
ZDLN electronic electric straight through double seat regulating valve adopts a double guide structure and is equipped with a 9610L series electronic straight stroke electric actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, precise flow characteristics, and convenient disassembly and assembly. Widely used for precise control of media such as gases, liquids, and vapors, it is true that process parameters such as pressure, flow rate, temperature, and liquid level are maintained at the given values. Especially suitable for media with large pressure difference, allowable leakage, and not very clean conditions.
There are various types of ZDLN electronic electric straight through double seat regulating valves, including standard type, bellow sealing type, jacket insulation type, etc. The nominal pressure rating of the product includes PN16, 40, and 64; The nominal diameter range is DN25-400. Applicable fluid temperatures range from -250 ℃ to+560 ℃ in various grades. The leakage standard is level II or IV. The flow characteristic is linear or equal percentage

Product features:
1, Dual seat structure
The straight through dual seat regulating valve adopts a dual seat structure, which can balance the pressure of two sealing surfaces, thereby reducing sealing surface wear and improving sealing performance. The double seat structure can also withstand larger flow rates, which is beneficial for reducing pressure loss and improving flow flux.
2, High traffic
The flow path of a straight through dual seat regulating valve is generally shorter, with a larger flow cross-sectional area, which can achieve a larger flow flux and is suitable for high flow applications.
3, Wide adjustment range
The direct dual seat regulating valve has a wide range of adjustment and can be used for regulating various media and working conditions. And it has high adjustment accuracy, fast response speed, and can achieve precise flow regulation.
4, Wide applicability
Direct dual seat regulating valves are suitable for various media, including liquids, gases, vapors, etc. And it has good control and stability performance, widely used in fields such as petroleum, chemical, metallurgy, power, heating, etc.
In short, the straight through dual seat control valve adopts a dual seat structure, with large flow rate, wide adjustment range, and wide applicability, making it an excellent control valve. Widely applied in various fields, it plays an important role in achieving flow regulation.
