The differences between butterfly check valves and swing check valves lie not only in their structural design but also in their typical applications. Although both valve types share the same functions—preventing backflow, enabling light-load pump starting, and reducing water hammer—their design characteristics and operational ranges differ.   Both valve types feature a disc-shaped...

PTFE-Lined Butterfly Valves are commonly used in piping systems to achieve flow shut-off and regulation, and they are widely applied in industries such as petroleum, chemical, metallurgy, and hydropower. In existing butterfly valve technology, the valve’s sealing primarily relies on soft sealing materials, such as rubber or polytetrafluoroethylene (PTFE).   These valves feature a seat s...

In industrial piping systems, high-temperature and high-pressure conditions have always placed stringent demands on valves. Traditionally, gate valves and ball valves have been the mainstay in such environments, offering reliable sealing performance and pressure-bearing capacity. With advances in valve materials and structural design, however, an increasing number of companies are now asking: &nbs...

In modern industrial and commercial projects, valve selection directly affects system efficiency and maintenance costs. Butterfly valves, with their simple design, reliable sealing, and lightweight construction, have become one of the most common flow control devices in HVAC systems as well as in municipal water supply, wastewater treatment, and cooling water circuits. But what makes butterfly val...

Have you ever considered whether a butterfly valve is suitable for your piping system design? Or have you experienced leakage or operational difficulties when using a butterfly valve under high pressure, high temperature, or viscous media?   Butterfly valves are widely used in water, gas, steam, and low-pressure piping systems due to their simple structure, lightweight design, quick operation...

1.Introduction   In the transportation and storage of cryogenic media such as liquefied natural gas (LNG), liquid nitrogen, liquid oxygen, and liquid hydrogen, the reliability and maintainability of valves are of critical importance. Cryogenic butterfly valves are not only capable of operating reliably under extreme low temperatures, but are also designed with “easy maintenance” i...

A butterfly valve is a type of rotary valve known for its compact structure, lightweight design, and fast opening and closing performance. It is widely used in industries such as water treatment, chemical processing, oil and gas, and power generation to shut off or regulate fluid flow.   What Is a Butterfly Valve? A butterfly valve is a type of valve that uses a circular disc (also known as a...

In today’s increasingly complex industrial landscape, where working conditions are becoming more demanding, valve selection plays a critical role not only in equipment efficiency but also in the overall safety and stability of the system.  Among various options, the triple offset metal seated butterfly valve stands out for its superior sealing performance and structural advant...

Aeration butterfly valves are critical devices widely used in ventilation, air conditioning systems, flue gas emission, and dust removal systems. To ensure their long-term stable operation and to maximize their service life, regular maintenance and proper operation are essential. 1. Correct Installation (1) Positioning: Ensure the aeration butterfly valve is installed in an appropriate location, a...

Butterfly valve, also known as flap valve, is a simple regulating valve that can be used for switching control of low-pressure pipeline media. Butterfly valve refers to a type of valve in which the closing element (disc or disc) is a disc that rotates around the valve axis to achieve opening and closing. Butterfly valves can be used to control the flow of various types of fluids such as air, water...
