1 . Fluid resistance , the resistance coefficient with the length of the pipe sections are equal.

2 . Simple structure , small size and light weight.

3 . Close and reliable mesh valve sealing surface material widely used plastic , sealing, has also been widely used in the vacuum system .

4 . Easy to operate, opening and closing rapidly , from fully open to fully closed as long rotation 90 °, to facilitate remote control .

5 . Easy maintenance , simple ball valve, seals are generally activities , removal replacement is more convenient.

6 . Wide range of applications , from small diameter to a few millimeters to a few meters high vacuum or high pressure can be applied .

Mine used high-pressure valve

Such valves are commonly used in high-pressure valve of existing mines , it withstand high pressure, using a U-shaped card fast access mode , use mine daily production to achieve rapid installation and removal , easy to use .

Ash discharge valve in the pipeline is mainly used for cutting, distribution and change the flow direction of the medium. Cinder ball form of the structure can be divided into : floating ball , fixed ball, elastic ball discharging valve is mainly used for cut off or connected line of medium , can also be used for fluid regulation and control , discharging valve compared with other types of valves with rotary output torque , open fast, smooth and reliable , widely applicable . Cinder ball valve rotary valve works by love to make the valve flow or occlusion.

Electric valve constructed by only a few parts , the data consumed Province ; small size, light weight , small size electric valve installation diagram , the drive torque, pressure regulating valve , simple, agile , just rotate 90 ° to Quick opening and closing ; and also at the same time has a good flow regulation efficacy and closed sealing characteristics , in large and medium caliber, scope of application of low pressure electric ball valves is dominated situation . When electric valve is full open position , the disc thickness is only when the medium flows through the body resistance , so that the valve by the pressure drop occurred very small, it has a better grip flow characteristics . Electric valve shells sealed and two metal seal type . Resilient seal valves, seals can be mounted on the body or attached to the disc perimeter. Take a long metal seal valve life in general than the elastic sealing valves , but difficult to achieve a complete seal. Metal seal can adapt to high temperatures , have the drawback that the elastic sealing temperature limits . If the request is dominated use electric valve as a flow , it is important to choose exactly the size and type of valve. Electric valve structure principle is particularly suitable for manufacturing large diameter valves . Electric ball has not only been widely used in the general industrial oil, gas , chemical, water treatment , etc., but also the use in thermal power plant cooling water system . Commonly used electric valve has two wafer type ball valve electric valve and flange electric . Wafer electric ball valve is stud connection between two pipe flanges , flanged electric valve is a valve with a flange with bolts on both ends of the valve on the pipe flange adapter flange . Strength properties of the valve is the valve in order to sustain the pressure medium . The pressure valve is a mechanical products suffer , therefore must have sufficient strength and rigidity to ensure the long-term use without causing deformation or rupture . Pneumatic valve pneumatic actuators by a ball valve configuration composed of a double-acting pneumatic actuators into pneumatic actuators and single- acting pneumatic actuators, controlled by a solenoid valve , the valve by switching action. Pneumatic valve can achieve intelligent control, fast turn on or off the pipe , the pipe network can effectively control and manage .
