There are many types of stainless steel ball valves on the market, including electric, pneumatic, and convenient. This section mainly introduces electric stainless steel balls used to cut or connect pipeline media. Used for fluids. Adjust and control. Compared to other valves, electric stainless steel ball valves have the following advantages:
1. Low fluid resistance, ball valves have the lowest fluid resistance among all valves. Even small diameter ball valves have relatively small fluid resistance.
2. Thrust bearings reduce the friction torque of the valve. A valve stem that can ensure long-term stable and flexible operation of the valve stem;
3. The valve seat has excellent sealing performance. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal and has valve sealing ability. As the medium pressure increases, the flow rate of the ball valve increases.;
4. The valve stem is tightly sealed. The packing seal on the valve stem is not easy because the valve stem is only used to simulate rotation and does not lift.
5. Materials such as polytetrafluoroethylene have excellent self-lubricating performance and low friction loss with rolling balls, resulting in a long service life.
6. The convex step of the stainless steel ball valve stem and the valve stem head installed at the bottom prevent the discharge of the valve stem, such as fire, damage to the valve stem seal, and the possibility of metal contact between the convex steps. 7) Static pressure function: Set a spring between the ball, valve stem, and valve body to generate a switching process. Output static electricity.
The electric stainless steel ball valve actuator adopts a new series of GT pneumatic actuators. Including double acting and single acting (spring return), gear rack transmission, safe and reliable. The AW series pneumatic actuator is driven by a fork, with a reasonable structure and large output torque. It has dual and single acting functions. The characteristics and advantages of electric stainless steel ball valves are as follows:
1. Gear type double piston, with large output torque and small volume.
2. The cylinder is made of aluminum and gold, with a light weight and beautiful appearance.
3. The manual operating mechanism can be installed up and down.
4. The gear rack connection allows you to adjust the opening angle and rated flow rate.
5. Electrical signal feedback commands and various accessories can be used to select actuators for automatic operation.
6. The IS05211 standard interface facilitates product installation and replacement.
7. Due to the adjustment of the joint screws at both ends, the adjustment range for standard products is ± 4 ° between 0 ° and 90 °. Ensure synchronization accuracy with the valve.
