Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.
Product Description

Product features
1、Compact structure, reasonable design, good rigidity of the valve, smooth channel, small flow coefficient 2、Sealing surface using stainless steel and hard alloy, long service life 3、Adopting flexible graphite packing, reliable sealing, lightweight and flexible operation
Globe valve, also known as the cut-off valve is the most widely used type of valve, it is popular because of the opening and closing process between the sealing surface of the friction is small, more durable, open height is not large, easy to manufacture, easy maintenance, not only for low and medium pressure, but also for high pressure. The closing principle of the globe valve is to rely on the pressure of the valve bar, so that the valve sealing surface and the valve seat sealing surface close to prevent the flow of media. Globe valve only allows the medium to flow in one direction, the installation of directional. Globe valve structure length is greater than the gate valve, while the fluid resistance, long-term operation, sealing reliability is not strong.

The butterfly plate of the clamp butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, the rotation Angle is between 0°-90°, rotate to 90°, the valve brand is fully open. This valve is generally installed horizontally. The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. And only n- Wenzhou Yuzheng Valve Co.,Ltd

Coupling, is a groove type pipe card, mainly used in dairy products, beer, food, beverage, pharmaceutical, biological engineering and other industrial fields.

Hexagon Nipple is a kind of fittings commonly used in industrial pipe connection. There are common equal diameter hexagonal outer wires and reduced diameter hexagonal outer wires, and the middle is a hexagonal section, and the two sides are changed in the form of thread connection.

The extended three-piece welded ball valve is widely used in various fields, and its quality and performance stability are not achieved by ordinary cast steel ball valves. The service life of welded ball valves is far greater than that of cast steel ball valves. The extended welded ball valves are widely used in urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other types of pipeline equipment.
