Application Of Electric Ball Valve
Electric ball valves do not require manual operation, but are intelligently operated. In the production process, the environment and site determine all factors. There are different electric ball valves used in high pressure, high temperature or low pressure and low temperature environments. The following points should be noted: 1. For low temperature and low pressure, the material does not require much adjustment.
2. In the case of high pressure and high temperature, high temperature and high pressure resistant materials should be selected as the electric ball valve material, such as stainless steel and alloy. These materials can withstand high pressure and high temperature.
3. The internal parts of the electric ball valve need to be replaced to reduce damage to the valve core, which is also beneficial to the flow of the medium and avoids coking and clogging of the electric ball valve.
4. When the electric ball valve is opened, some vibration-avoiding machinery can be installed to prevent damage to the internal structure of the electric ball valve core when it is opened.
Product Description
The electric threaded ball valve adopts an integrated structure and is matched with the electric actuator. It can operate by inputting a (4-20mA DC, 0-10V DC or 1-5V) signal or single-phase power supply. It has strong functions, small size, light weight and low cost. , reliable performance, simple matching, large circulation capacity and other characteristics. At present, the valve is widely used in industrial automation control systems in food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and scientific research equipment, electric power and other industries.
The Use Of Ball Valve
Since ball valves usually use rubber, nylon and polytetrafluoroethylene as seat sealing ring materials, their service temperature is limited by the seat sealing ring material. The cut-off function of the ball valve is accomplished by the metal balls pressing against each other between the plastic valve seats under the action of the medium (floating ball valve). Under the action of a certain contact pressure, the valve seat sealing ring will undergo elastic-plastic deformation in local areas. This deformation can compensate for the manufacturing accuracy and surface roughness of the ball and ensure the sealing performance of the ball valve. And because the seat sealing ring of a ball valve is usually made of plastic, when selecting the structure and performance of the ball valve, the fire resistance and fire prevention of the ball valve must be considered, especially in petroleum, chemical industry, metallurgy and other departments, in flammable and explosive media When ball valves are used in equipment and piping systems, more attention should be paid to fire resistance and fire prevention.

Electric threaded ball valves and butt welded ball valves are divided into integral (one-piece), two-stage and three-stage types. The valve body is cast using advanced technology introduced from Taiwan. It has a reasonable structure and beautiful appearance. The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to start. The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity heats up abnormally, the valve stem will Will not be impacted. Two-piece and three-piece ball valves also have butt welding (BW) and socket welding (SW) connection forms. They can also be equipped with international standard ISO bracket platforms and locking devices.
