The Introduction of Butterfly Valve
Butterfly Valve Introduction
Sanitary butterfly valves are produced by our factory, we introduced advanced foreign technology, based on the use of precision J-shaped elastic ring and three eccentric multi-level metal hard seal structure, is widely used in the governance, power, petrochemical industries such as water supply, drainage and municipal construction and other industrial pipelines, for regulating the flow and load-off fluid use. The valve has three eccentric structure, seat and disc sealing surface are made of different hardness and stainless steel, it has good corrosion resistance, long service life, the valve has two-way sealing function, the product complies with national valve pressure testing standard GB / T13927-92.
The working principle of butt welding butterfly valve:
The structure of butterfly valve is simple, small size, light weight. And only need to rotate 90 °, it can be quickly opened and closed with simple operation, while the sanitary valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the disc thickness is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. Butterfly valve has two kinds of sealed seal and metal seal type. Elastic seal valve, ring can be embedded in the valve body or attached to the disc around.
Sanitary Butterfly Valve Features:
1 with high temperature, high pressure, corrosion resistance, wear and other characteristics.
2 compact, small size, light weight, flexible operation, easy to use.
3 This valve is not blue, the pipe and the insulation bandage brings great convenience and beauty.
4 three-dimensional eccentric elastic or multi-level hard seal structure, the sealing performance is reliable with zero leakage.
5 The use of welded structure, so that the valve and pipe plane achieved a permanent zero leakage.

Lined check valve
Lifting type lining fluorine check valve
Lift-type lining fluorine check valve is designed to control corrosive or corrosive media, the valve body cavity surface covered with a variety of fluorine plastic options, with many characteristics such as high strength, good corrosion resistance; is suitable for different operating temperatures and Fluid piping, to prevent all kinds of pipe or equipment open and close on the media upstream.
Swing type lining fluorine check valve
The shaft of check valve is integrated with the valve disc. The shaft of the fluorine-lined plastic is embedded in the special groove formed between the valve body and the sanitary valve cover. The opening, closing and the sealing is flexible and reliable. In addition to the valve body, the valve flap, the reset spring is also all lining the corrosion-resistant fluoroplastics with rational design, so that the valve is in the low pressure area which can also produce sufficient sealing pressure to ensure that the reliability of valve in the low pressure area.
Vertical lining fluorine check valve
The main models are fully lined vertical lining fluorine sanitary check valve, it is a new structure, the valve flap is for the hemisphere, the common feature is the lining valve flap along the axis of the valve body to do lifting movements. Vertical lining fluorine check valve is a kind of media automatic valve which rely on the flow of the media itself and automatically open and close the valve flap which is used to prevent the reverse flow.

Insulation check valve
Lift type thermal insulation check valve
Lift-type insulation check valve is in the lift check valve based on the welding metal jacket for steam or other insulation, cold medium, to ensure that the valve medium can work properly. It has a good thermal insulation property, is effective in reducing heat loss in the pipeline medium. Insulated jacket ball valve has integral jacket structure design, more uniform insulation, cold, jacket with carbon steel pipe welding which is more than the pressure of a solid casting. Jacket, the outside of the valve body and jacket welding, the maximum pressure of steam or cold water is 1MPa.
Swing-type thermal insulation check valve
Swing-type insulation check valve between the two ends of the welding flange with a metal jacket, the side of the check valve, the bottom of the jacket with the connection port for the steam or thermal oil, which play on the Check the insulation effect of the valve to ensure the normal flow of viscous medium. The sanitary check valve is mainly used in chemical, petroleum, asphalt, pharmaceutical, metallurgical and other industries in the pipeline system, the main role is to transport at room temperature which will be solidified, easy to crystallize the medium.
Vertical Insulation Check Valve
Vertical insulation check valve is designed with jacket insulation, jacket with carbon steel pipe welding is more resistant than casting a solid. The product has good thermal insulation property, and can effectively reduce the medium heat loss in the pipeline. Sanitary valve is mainly used in petroleum, chemical, asphalt, metallurgy, pharmaceutical, food and other systems, to prevent the transmission of conventional high-viscosity solidification.
