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 ...

Metal seated butterfly valve is that both sides of the seal are made of metal material or other hard materials. This seal has relatively poor sealing performance, but is resistant to high temperatures, abrasion and mechanical properties. Metal seated is often combined of such as: steel + steel, steel + copper, steel + graphite, steel + alloy steel. The steel here may also be cast iron, c...

The emergence of the triple eccentric butterfly valve, or triple offset butterfly valve, has changed the stereotype of the butterfly valve. In the past, people usually thought that butterfly valves could only be used on ordinary pipelines at normal temperature and low pressure, and were not resistant to high temperature or high pressure.   Buttriple eccentric butterfly valves have d...
