N-series Pneumatic Double Seat Regulating Valve

The N series new pneumatic film two-seat regulating valve developed and produced by our company features a double guide structure and multi-spring actuator. It boasts a compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, convenient disassembly, and more. This product finds wide application in the precise control of gas, liquid, steam, and other media to maintain given values for process parameters such as pressure, flow, temperature, and liquid level. It is particularly well-suited for applications with large pressure differences or where significant leakage of less clean media is permissible. Moreover it is widely utilized in chemical processing plants，petroleum refineries，metallurgical facilities，power stations，textile mills，paper production plants，and pharmaceutical manufacturing processes for automatic regulation and remote control.

【Product Characteristics】

1.The dual guide structure at the top and bottom enhances the overall valve stability of the machine.

2.The unbalanced force is minimal; Due to the hydrostatic pressure acting simultaneously on both spools in a manner that cancels each other out, the unbalanced force remains small, enabling a larger pressure difference and reducing the thrust required by the actuator.

3.Enhanced flow capacity; In comparison to control valves of similar size, the two-seat valve exhibits greater fluid flow capacity, approximately 20-50% more than that of a single-seat valve.
