The electric emergency shut-off ball valve is designed for quick cutting and regulation, with the valve directly connected to the actuator. The electric actuator features an integrated servo system, eliminating the need for an additional servo amplifier. Operation can be controlled by inputting a 4-20 mA signal and a 220V AC power supply. This valve is characterized by easy installation, compact construction, small size, light weight, low resistance, stable operation, and reliability. Depending on customer requirements, the actuator can be equipped with electronic actuators such as UNIC, PSQ, HQ, DHL, or pneumatic actuators like GTX and AL.
● Anti-Static Structure: The 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?
Using mechanical principles, the valve is connected to the connecting rod. Inside the electric actuator, the input electrical pressure is applied to the piston, generating thrust. This causes the gears to rotate under the piston's push, driving the output shaft to rotate and causing the valve stem to turn. As a result, the internal ball valve rotates synchronously with the valve body, changing the cross-sectional area of the fluid to achieve the goal of regulating the medium flow.
