Pneumatic Diaphragm Valve

Pneumatic diaphragm valve is a new type of electric valve that uses compressed air as the power source and converts the pneumatic signal into an electrical signal through an actuator to drive the valve action. It has the advantages of simple structure, small volume, light weight, etc. It use in the automatic control system of petroleum, chemical, metallurgical and other industries as a regulating and intercepting device.

The difference between OS&y gate valve and NRS gate valve


Gate valves are essential components in pipeline systems, used to control the flow of fluid by opening or closing a gate mechanism. Among the various types of gate valves available, the two most common are the OS&Y (Outside Screw and Yoke) gate valve and the NRS (Non-Rising Stem) gate valve. While both valves serve the same purpose, they differ significantly in their design, construction, and application. In this article, we will explore the differences between OS&Y and NRS gate valves in detail.

Diaphragm Valve

Diaphragm valves are a unique type of shut-off valve that control the flow of fluids in pipelines by using the movement of the diaphragm on the valve stem to regulate the opening and closing of the valve. The tightness of these valves is highly prominent, and their applications are wide-ranging due to the variety of diaphragm materials that can be used. Let’s take a closer look at the different types of diaphragm valves and their functions.
