Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.

Pneumatic Adaptation
Pneumatic operation can be considered according to the project control requirements and valve size. Please provide the required operating conditions for technical review.
Typical Applications
Water Transmission and Distribution
For water transmission mains, distribution networks and pipeline isolation points where valve size, pressure rating and installation dimensions must match the pipeline design.
Water Treatment Plants
For isolation duties in municipal and industrial water treatment systems. Material and seat selection should be based on water quality and operating conditions.
Pumping Stations
For pump inlet and outlet pipelines where the valve configuration, operating torque and installation arrangement require engineering review.
Municipal Infrastructure
For water supply and infrastructure projects specifying relevant EN valve and flange standards.
Industrial Water Systems
For industrial water pipelines requiring a double-flanged butterfly valve with specified materials, pressure ratings and operating arrangements.
Application suitability must be confirmed against the actual medium and operating conditions.
