The electric screw ball valve, driven by an electric actuator, is specifically designed for the regulation and control of pipeline media. It features external thread connections, making it primarily suitable for low-pressure and small-diameter pipeline systems. The pneumatic screw ball valve consists of a ball, seat, seal ring, stem, and pneumatic actuator. The ball section offers excellent sealing performance, effectively preventing media leakage.
● Easy Installation and Maintenance: Compact design, small size, easy to install and maintain. Even in confined space, this valve can achieve efficient fluid control and adapt to a variety of complex working conditions.
● Superior Sealing Performance: The pneumatic internal thread ball valve shows excellent sealing effect, thanks to the selection of special sealing materials and design, ensuring that the valve can still maintain excellent sealing state in high pressure, high temperature or facing corrosive media, effectively avoiding leakage.
● Easy Operation: Using pneumatic actuators, valves can be opened or closed quickly, significantly improving work efficiency. In addition, pneumatic actuators also have pressure loss protection function, once the gas or power supply is interrupted, the valve can automatically close or remain in a safe state.
● Widely Application: The valve is widely used in petroleum, chemical industry, natural gas, water treatment and other fields, can meet the needs of various media control.

Q1:What is the main suitable of this valve?
This product is especially suitable for steel, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas and other media.
Q2:What mechanical principle is used?
The design characteristics of the valve lie in its unique structure and the operation method of the electric actuator. The key part of the valve is a rotatable ball with holes, located inside the valve body. Once the electric actuator receives a control signal, it uses electrical energy to rotate the ball. The rotation range of the ball is typically 90 degrees. When the ball rotates to a position parallel to the channel direction, the valve opens fully, ensuring unobstructed flow of fluid; when the ball rotates to a position perpendicular to the channel direction, the valve closes completely, thus preventing fluid flow.
Our electric internally threaded ball valves excel in flow control, precisely meeting the fluid control requirements of various process flows, thereby enhancing product quality. Through optimized design, we have reduced fluid resistance and lowered energy consumption while complying with environmental standards, supporting companies in achieving their green production goals. We offer a variety of specifications and configurations to suit different application scenarios, providing customized solutions. Our team of professional technicians offers comprehensive pre-sales consultation, installation and commissioning, as well as after-sales service, ensuring worry-free use for our customers.
