Lined Ball Valve There are many categories in the market now, including electric ones, pneumatic ones, and dynamic ones. Here we mainly introduce electric stainless steel balls, which are used to cut off or connect the medium in the pipeline, and can also be used to regulate and regulate fluids. control. Electric stainless steel ball valve has the following advantages compared with other valve types.
1. The fluid resistance is small, and the ball valve has the smallest fluid resistance among all valves. Even the reduced diameter ball valve has a very small fluid resistance; 2. The thrust bearing reduces the friction torque of the valve stem, allowing the valve stem to operate for a long time. Smooth and flexible;
3. The valve seat has good sealing performance and uses a sealing ring made of elastic materials such as polytetrafluoroethylene. The structure is easy to seal, and the valve sealing capacity of the ball valve increases as the medium pressure increases;
4. The valve stem seal is reliable. Since the valve stem only performs imitation rotation movement and does not perform lifting movement, the packing seal of the valve stem is not easy to be damaged, and the sealing capacity increases as the pressure of the medium increases;
5. Since materials such as polytetrafluoroethylene have good self-lubricating properties and have little friction loss with the ball, the ball valve has a long service life; 6. The bottom-mounted valve stem and the convex steps on the valve stem head prevent the valve stem from blowing out. If the valve stem seal is damaged due to fire, metal contact can be formed between the convex step and the valve body to ensure the valve stem seal;
7. Anti-static function: A spring is set between the ball, valve stem, and valve body, which can discharge the static electricity generated during the switching process.
The actuator of the electric stainless steel ball valve adopts a new series of GT-type pneumatic actuators, which are double-acting and single-acting (spring return), with rack and pinion transmission, safe and reliable; large-diameter valves adopt a series of AW-type pneumatic actuators. Fork transmission, reasonable structure, large output torque, available in double-acting and single-acting types.
1. Gear-type double pistons, large output torque and small size.
2. The cylinder is made of aluminum gold, which is light in weight and beautiful in appearance.
3. Manual operating mechanisms can be installed on the top and bottom.
4. The rack-type connection can adjust the opening angle and rated flow rate.
5. The actuator can be equipped with optional live signal feedback instructions and various accessories to achieve automated operation.
6. IS05211 standard connection provides convenience for product installation and replacement.
7. The adjustable joint screws at both ends allow the standard product to have an adjustable range of ±4° between 0° and 90°. Ensure synchronization accuracy with the valve. Options for electric stainless steel ball valve actuator accessories
The following accessories can be selected according to different controls and requirements:
Cut-off accessories: single solenoid valve, double solenoid valve, limit switch transmitter.
Adjustable accessories: electrical positioner, pneumatic positioner, electrical converter.
Air source treatment accessories: air filter pressure reducing valve, air source treatment triple piece.
