Performance of knife gate valves
1. Valve control can be local and remote control, but also according to user requirements to achieve remote position display and remote centralized control. 2. Light weight: the body is made of carbon steel, the weight is about 20%-30% less than the traditional gate valve, easy to install and maintain. 3. The use of the valve can improve the sealing performance of the conveying pipeline system, prevent leakage to the maximum extent, improve production efficiency, protect the environment will play a positive role in promoting. 4. Sealing surface with high wear resistance, corrosion resistant ceramic materials, Mosaic technology, high corrosion resistance, good wear resistance, so that the valve life is long, cost-effective than the ordinary valve is increased 10 times.

Butterfly valve folding common failure
Valves can be used to control the flow of air, water, steam, all kinds of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluids. In the pipeline mainly plays the role of cutting and throttling. Butterfly valve opening and closing part is a disc shaped butterfly plate, in the valve body around its own axis, so as to achieve the purpose of opening and closing or adjustment.
The characteristics of butterfly valve
Butterfly valve is also called flip valve, is a simple structure of the control valve, can be used for low pressure pipeline medium switch control butterfly valve refers to the closing part (disc or disc) for disc, around the valve shaft to achieve open and close a valve.
Butterfly valve development history
Butterfly valve is a disc type opening and closing parts reciprocating around 90° to open, close or adjust the medium flow of a valve. Butterfly valve is not only simple structure, small volume, light weight, material consumption, small installation size, small driving torque, simple operation, rapid, and can also have a good flow regulation function and closed sealing characteristics, is one of the fastest growing valve varieties in recent ten years. Butterfly valves are widely used. The variety and quantity of its use are still continuing to expand, and to high temperature, high pressure, large caliber, high sealing, long life, excellent regulating characteristics, as well as a multi-function valve development. Its reliability and other performance indexes have reached a high level.
