Fixed electric ball valves are specifically designed for two-position shut-off and control applications. The connection between the valve and the actuator is direct. The electric actuator integrates a servo system, eliminating the need for an additional servo amplifier. Operation can be controlled by inputting a 4-20 mA signal and a 220VAC power supply. This valve features easy connectivity, compact structure, small size, light weight, low resistance, and high reliability. Depending on specific user requirements, it can be equipped with electronic actuators such as UNIC PSQ, HQ, DHL, or pneumatic piston actuators like GTX, AL.
● Anti-Static Structure: The ear axis sphere is equipped with an electrostatic protection device to ensure that the electrostatic discharge device can form an effective electrostatic channel between the spheres or between the spheres and the rod.
● Trunnion-Mounted Ball: This structure is composed of a fixed ball and a floating seat ring, which can absorb the lateral load generated by the pressure acting on the ball.
● Self-Seated Valves: In valves designed for standard service, the elastic material is embedded in the metal seat frame. In addition to the metal-to-metal contact between the ball and the seat ring, an additional soft seal seat is provided.

Q1:What is the main suitable of this valve?
This product is especially suitable for steel, aluminum, fiber, small solid particles, pulp, coal ash, oil and gas media.
Q2:What mechanical principle is used?
Through mechanical principles, the valve is connected to the connecting rod. Inside the electric actuator, the input electrical pressure acts on the piston, generating the corresponding thrust. This causes the gears to rotate under the drive of the piston, which in turn rotates the output shaft and pushes the valve stem to rotate. Therefore, the internal ball valve rotates synchronously with the valve body, changing the cross-sectional area of the fluid to achieve the purpose of regulating the medium flow.
We meticulously manufacture electric emergency shut-off valves, using cutting-edge materials and technology to ensure their exceptional durability and reliability. In emergencies, these valves can quickly and effectively cut off fluid flow, protecting people and property. By integrating with advanced control systems, our electric emergency shut-off valves achieve remote monitoring and operation functions, further enhancing safety and convenience. These valves are widely used in various industrial environments such as oil, chemical, and natural gas industries, meeting the needs of different sectors.
