Fixed electric ball valves are suitable for two-position shut-off and control applications. The connection between the valve and the actuator is direct. The electric actuator is equipped with 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. It features easy connection, compact structure, small size, light weight, low resistance, and stable, reliable operation. Depending on user requirements, the actuator can be equipped with electronic actuators such as UNIC, PSQ, HQ, DHL, or pneumatic piston actuators like GTX and AL.
● Anti-Static Structure: The ear axis sphere is equipped with electrostatic protection structure, and the electrostatic discharge device forms an electrostatic channel between the spheres or between the spheres and the rod.
● Trunnion-Mounted Ball: It has a fixed ball and a floating seat ring, the bearing absorbs the lateral load generated by the pressure acting on the ball.
● Self-Seated Valves: In valves designed for standard service, the elastic material is inserted into the metal seat frame to provide a soft seat in addition to the metal-to-metal seat between the ball and the seat ring.

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?
Using mechanical principles, the valve is connected to the connecting shaft. The input electrical pressure inside the electric actuator acts on the piston, generating a certain thrust. This causes the gear output to rotate under the drive of the piston, which in turn rotates the gear's output shaft, pushing the valve shaft to rotate. As a result, the ball valve inside rotates with the valve, changing the flow area and achieving the purpose of altering the medium flow rate.
We use advanced materials and technologies to manufacture electric emergency shut-off valves, ensuring their durability and reliability. In emergencies, these valves can respond quickly to cut off fluid flow, protecting people and property. Combined with advanced control systems, our electric emergency shut-off valves can be remotely monitored and operated, enhancing safety and convenience. They are suitable for various industrial environments, such as the oil, chemical, and natural gas industries, meeting a wide range of needs.
