Electric three-piece ball valve< )r , , is a valve that (the ball) rotates around the axis perpendicular to the channel , which is composed of a rotary angle-stroke electronic electric actuator and a disc-type ball valve structure. It is a rotary type high-performance regulating or switching valve. It accepts the input and output of current signals or voltage signals from industrial automation control (system) instruments. It can realize proportional adjustment or two-position switch control of the fluid medium in the process pipeline, thereby achieving automatic control of parameters such as flow, pressure, temperature, and liquid level of the fluid medium. Electric three-piece ball valves (internally threaded ball valves) and butt welding ball valves are suitable for various pipes with working temperatures of ~℃ (the sealing ring is reinforced polytetrafluoroethylene) or ~℃ (the sealing ring is para-polystyrene). On the road, it is used to cut off or connect the medium in the pipeline. Using different materials, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, etc.
Electric three-piece ball valve< )r , , Product Features
< )r , ,
Electric three-piece ball valve< )r , , (internally threaded connection ball valve) and butt welding connection ball valve are divided into integral (one-piece) two-stage and three-stage types. The valve body is cast using advanced technology introduced from Taiwan, with a reasonable structure and beautiful appearance. The valve seat adopts an elastic sealing structure, which ensures reliable sealing and easy opening and closing. The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve chamber is abnormally pressurized, the valve stem will not be flushed out. The two-piece and three-piece ball valves also have butt welding (B) and socket welding connections, and can be equipped with international standard bracket platforms and locking devices. A switch positioning mechanism can be set up and locked as needed to prevent misoperation. Driving mode: manual, electro-pneumatic.
< )r , ,
Electric three-piece ball valve< )r , , has small fluid resistance and is the lowest among all valves The smallest one uses or power supply voltage as power, receives (or) current signal or voltage signal, and can control the operation. It can complete the opening and closing action or adjustment action by rotating the ball with the torque output by the angular stroke.
< )r , , fully electronic electric actuator, adopts electromechanical integration structure, with in-machine servo operation and opening signal position feedback Position indication, manual operation and other functions, strong functions, reliable performance and simple wiring. By inputting current signal or voltage signal, the rotation angle of the ball core (any angle) can be changed to achieve proportional adjustment action.
< )r , , The ball core channel is flat and smooth, and it is not easy to deposit media, and the ball can be passed through the pipeline. Simple structure, light weight and good sealing performance. Especially suitable for occasions requiring zero leakage rate.
Electric three-piece ball valve< )r , , Detailed description of electric actuator
< )r , , series electric valve actuators, with their novel and unique design, advanced and exquisite technology, high-quality imported parts and scientific and rigorous quality inspection, are unique in the automated valve manufacturing at home and abroad. The series of electronic electric valve actuators has pushed the precision, digitalization and intelligence of valve electric devices to a new stage, becoming a rising star in the liquid automation control industry.
< )r , , The series of products mainly include three categories: switch type, feedback type, adjustment type (electronic type), which can be matched with various ball valves, butterfly valves and other rotary valves. The output torque is from. Light weight (equivalent to / of similar products). It has many advantages including exquisite appearance, compact structure, easy installation, intelligent control, digital setting, digital display valve position, no need for maintenance and safe use.
