Fixed electric ball valves are designed specifically for dual position closing and control applications. The connection between the valve and the actuator is direct. Electric actuators have integrated servo systems and do not require additional servo amplifiers. Operation can be controlled by inputting a 4-20mA signal and a 220VAC power supply. This valve has the characteristics of easy connection, compact structure, small volume, light weight, low resistance, and stable reliability. According to specific user requirements, actuators can be equipped with electronic actuators such as UNIC PSQ、HQ、DHL， Or pneumatic piston actuators, such as GTX and AL.
● Anti-Static Structure: The ear shaft ball is equipped with an electrostatic protection mechanism to ensure that the electrostatic discharge device can form an effective electrostatic channel between the balls or between the balls and the rod.
● Trunnion-Mounted Ball: This structure consists of a fixed sphere and a floating seat ring, which can absorb the lateral load generated by the pressure acting on the sphere.
● Self-Seated Valves: In valves designed for standard service, 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 sealing seat is also 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, valves are connected to connecting rods. Inside the electric actuator, the input electrical pressure acts on the piston, generating corresponding thrust. This will cause the gear to rotate under the drive of the piston, thereby causing the output shaft to rotate and pushing 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 flow rate of the medium.
We carefully manufacture electric emergency shut-off valves using cutting-edge materials and technology to ensure their excellent durability and reliability. In emergency situations, these valves can respond quickly and effectively cut off fluid flow to protect personnel and property. By integrating with advanced control systems, our electric emergency shut-off valve achieves remote monitoring and operation capabilities, further improving safety and convenience. These valves are widely used in various industrial environments such as petroleum, chemical, and natural gas, meeting the needs of different industries.
