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.

farpro diaphragm valve

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.

automated production of farpro valve

The impact of the great era of automated production on the valve industry

Automated production will eventually eliminate manpower, as is the case with valves, and other production industries. We will eventually free our hands.

This is actually a good thing in the long run, and there may be worker unemployment in the short term. But in the long run, efficient production capacity will lead to higher social output and building capacity. Thus allowing everyone to be more productive with less work.

butterfly valve structura general

Butterfly Valve Structure Genenal

Butterfly valve structure is a type of quarter-turn valve that uses a disc-shaped closure element, the butterfly disc, to control the flow of fluid. The butterfly disc is mounted on a shaft and is positioned in the center of the valve body, which is a round or oval-shaped pipe. The disc rotates around the shaft to regulate the flow of fluid through the valve.

extraction check valve

Extraction Check Valve

Extraction check valves play an important role in preventing backflow and protecting valuable equipment from damage in steam and water lines. These valves are specifically designed for use in extraction lines from steam turbines to feedwater heaters, heating systems, or process equipment. The extraction check valve is engineered for exceptional reliability and can be configured to remain open until closed by a cylinder actuator on signal.
