Concentric and Eccentric : structure, application and selection guide
The butterfly valve commonly divided in to these two general types, Concentric is sealed by the rubber, according to the rubber type it can be suitable for many substances, like water, or some chemical. But it usually used in below PN 16. Eccentric butterfly valve include the double or triple eccentric/offsets, the disc achieves a “cam-like rotation” during opening and closing, completely eliminating frictional wear. Taking the triple offset structure as an example, the valve stem axis forms a compound angle with the sealing surface, ensuring zero leakage even under high temperature and high pressure conditions.

The way the gate valve moves
When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only rely on the medium pressure to press the sealing surface of the ram to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing.

How to prevent Water Hammer in industrial piping sysytem?
Water hammer or hydraulic shock occurs in industrial piping systems when liquid that is flowing quickly is abruptly stopped or redirected. Water hammer happens during an instantaneous change in flowing and presents as a very high-pressure spike that rushes through the pipeline, has an audible sound, and can damage components such as pipes, valves, pumps, and instruments. More specifically, fast-acting valve operation (ball, butterfly and plug) caused primarily by the speed of operation.

The core significance of ISO5211 standard
ISO5211 is an important standard set by the International Organization for Standardization (ISO) for connecting valve actuators to industrial valves. Its main goal is to make sure that part-turn valves (like butterfly valves and ball valves) and actuators are compatible and can be easily interchanged worldwide. The standard clearly defines the dimensions of flange connections, torque requirements, hole patterns, and drive structures.

Selection Of Butterfly Valves
The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. The butterfly valve has a simple structure, small size, light weight, only a few parts, and only needs to rotate 90° to quickly open and close, simple to operate, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance of the medium when it flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics.

The Importance of Valve Coating Thickness: Ensuring Durability and Performance
When it comes to industrial valves, the quality and longevity of the coating applied to the valve’s surface are critical factors that affect both its durability and performance. Valve coating thickness plays a vital role in protecting valves from corrosion, abrasion, and wear, which can otherwise lead to premature failure and costly downtime. In this article, we will explore why coating thickness is so important, and how it directly impacts the valve’s effectiveness in harsh environments.
