Butterfly valves are popular in industrial piping systems due to their simple design, compact size, quick operation, and low cost. However, leakage remains a common issue. It primarily manifests in two forms: internal leakage, where the valve doesn't seal shut, allowing fluid to pass through; and external leakage, where fluid escapes around the stem, body connections, or flange seals.

The tilting check valve with weight hammer manufactured and supplied by KEFA VALVE have been successfully installed and put into trial operation in a water project in Southeast Asia. This application in the water treatment sector once again demonstrates the critical role of KEFA VALVE in ensuring the safety and efficiency of modern water systems. Adhering to its quality-first and service-first philosophy, KEFA VALVE continues to provide high-quality valves and services for water infrastructure projects worldwide.

Some customers may be confused about the difference between AWWA C509 and AWWA C515 when purchasing an AWWA gate valve. As a professional manufacturer of AWWA gate valves, we offer the following suggestions. AWWA C509 and AWWA C515 are two different types of resilient-seated gate valve standards published by the American Water Works Association (AWWA). Here are detailed descriptions and differences between these two standards:

In industrial fluid control, butterfly valves play a key role in adjusting, guiding and shutting off the flow of liquids, gases and slurries inside pipeline systems. The flange butterfly valve is a common connection design. It has integral flanges on both ends of its body, which can be firmly connected to pipeline flanges with bolts.

Flange connection, as one of the important connection methods in pipeline construction, originated from the Industrial Revolution at the end of the 18th century and was initially mainly used for cast iron low-pressure steam pipelines. With the development of technology and the rise of the petrochemical industry, the requirements for flanges are constantly increasing with the increasing demand, and international standards are also constantly improving and unifying with this process. Various connection methods such as welding, threading, clamps, etc. also appear in pipeline systems.

Butterfly valves play a vital role in water management systems due to their compact design, quick operation, and reliable sealing. KEFA Valve Group, with 60 years of expertise in water treatment, offers advanced butterfly valve solutions tailored for municipal water supply, wastewater treatment, seawater applications, and hydraulic engineering.

Butterfly valves are vital for pipeline flow control. Wafer-style designs offer installation flexibility in compact spaces, while lug-style ones provide stronger pressure resistance.

Butterfly valves are versatile flow-control devices widely used in industries such as water treatment, oil and gas, chemical processing, and HVAC systems.
