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...

1. Before installation, it is necessary to carefully check whether the logo and certificate of conformity of the butterfly valve meet the requirements for use. After verification, cleaning should be carried out. 2. Butterfly valves can be installed at any position on the equipment pipeline. However, if there is a transmission device, it should be installed vertically, that is, the transmission dev...

Direction When installing the butterfly valve, pay attention to the installation arrow on the valve body. If it is two-way pressure, it can achieve two-way sealing, and there is no installation direction. Water Inlet Configuration There are elbows and T-shaped pipes on the water inlet side of the butterfly valve, which cause the fluid to bend and distribute unevenly. When the fluid flows into the ...

The vacuum butterfly valve is a common pipeline control valve, mainly used for fluid control in vacuum pipelines. Mainly used in petrochemical industry, metallurgical machinery industry, nuclear industry vacuum valve, etc. Structural Characteristics 1. It is designed and manufactured by adopting a new structural form welded by centerline butterfly plate and short structural steel plate. 2. Compact...

Overview Ultra-low temperature butterfly valves are mainly used in pipeline systems of liquefied natural gas and liquid nitrogen to control the opening and closing or adjustment of the pipeline equipment. The product adopts a double offset structure and an elastic metal sealing structure. The double offset structure can greatly eliminate unnecessary overloading and scraping of the disc and sealing...

Butterfly valve is a common valve that can be used for regulating performance, and it is widely used in today's valve applications. The most common fault of butterfly valve in use is that the sealing surface is easy to leak. What measures should we take to prevent the butterfly valve from leaking? 1. Ensure the clearance between the sealing surfaces. Since the sealing between the rubber seal ring ...

As a component used to realize the on-off and flow control of pipeline system, butterfly valve has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. There is an advanced butterfly valve: three eccentric metal hard seal butterfly valve. The valve body and the valve seat are connected components, the sealing surface of the valve seat is overlaid ...
