ZXS type pneumatic thin film angular single seat regulating valveDetailed product description：

The ZXS pneumatic thin film angular single seat regulating valve adopts a top guide structure and is equipped with a multi spring actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, S-shaped fluid channel, low pressure drop loss, large valve capacity, precise flow characteristics, and easy disassembly and assembly. The ZXS type pneumatic thin film angular single seat regulating valve is widely used for precise control of gas, liquid and other media, with process parameters such as pressure, flow rate, temperature, and liquid level maintained at given values. It is particularly suitable for regulating high viscosity fluids containing suspended solids and particulate matter with small leakage and small pressure difference before the valve, which can avoid coking and blockage, and facilitate self-cleaning and cleaning.

There are various types of ZXS regulating valves in this series, including standard type, regulating cut-off type, corrugated pipe sealing type, jacket insulation type, etc. The nominal pressure rating of the product includes PN10, PN16, PN40, and PN64; The valve body diameter range is DN20~200. Suitable for fluid temperatures ranging from -200 ℃ to 560 ℃ in various grades. The leakage standard has IV or VI level. The flow characteristics are linear or equal percentage. A variety of varieties and specifications are available for selection.

Product features of ZXS pneumatic thin film angular single seat regulating valve:

1. Top oriented, bottom in and side out, simple flow path, low resistance, and large valve capacity.
2. The adjustable range is large, with an inherent adjustable ratio of 50, and the flow characteristics include straight lines and equal percentages.
3. The actuator adopts a multi spring structure, reducing both height and weight by 30%.
4. The ZXNV bellows sealed regulating valve forms a complete seal for the moving valve stem, blocking fluid leakage.
5. The ZXNJ type regulating valve is equipped with an insulation jacket, which is used in situations where the fluid is prone to crystallization and solidification after cooling, causing blockage.

Installation instructions for ZXS pneumatic thin film angular single seat regulating valve:
1、 Check whether the parts of the whole machine are damaged or loose. For media that are harmful to human health, strength sealing, leakage, and accuracy testing must be carried out.
2、 Before installation, the pipeline should be cleaned, and there should be sufficient straight pipe sections and filters at the valve inlet. The flange connection between the valve body and the pipeline should pay attention to coaxiality.
3、 The installation site should consider the safety of personnel and equipment, which is both convenient for operation and conducive to disassembly and maintenance.
4、 Valves should be installed upright and vertically on horizontal pipelines. If necessary, they can be installed at an angle or in situations where the valve has a large self weight and vibration, a support frame should be used to avoid horizontal installation as much as possible.
5、 The direction of medium flow should be consistent with the arrow on the valve body. The gas source should be dry and oil-free, and the valve should be used in an environment with a temperature range of -25~55 ℃.
6、 In order to ensure continuous production even when the self-control system malfunctions or valves are under maintenance, a bypass valve should be installed. The flow characteristics and stroke of the bypass valve should be consistent with the original valve selection.
