Definition of Electric High-Pressure Flange Ball Valve

The main components of the electric high-pressure flange ball valve are forged, which overcomes potential defects of cast steel valves and enables the valve to maintain uniform pressure resistance of its structure under the maximum operating pressure.

Applicable Media: Non-corrosive media such as water, oil, and gas, as well as acid-base corrosive media.

The electric high-pressure ball valve is applied in industries including chemical engineering, petroleum, natural gas, and metallurgy, as well as in long-distance natural gas transmission pipelines with hydrogen sulfide-containing media, high impurity content, and severe corrosion.

Structural Principle of Electric High-Pressure Flange Ball Valve

The electric high-pressure flange ball valve features the following key characteristics: It is a three-piece connected forged steel fixed ball valve, where the valve body is divided into three parts at the two valve seat positions along the cross-section perpendicular to the axis of the valve passage. The entire valve is symmetric left and right along the central axis of the valve stem. It is mainly used in pipelines for cutting off, distributing, and changing the flow direction of media.

Its large pivot structure ensures the accurate central position of the ball under high pressure, guaranteeing excellent operating performance of the valve; the standard valve seat adopts a spring structure, which pushes the valve seat against the ball to ensure good bidirectional sealing performance at the inlet and outlet; the valve body cavity can discharge outward through the built-in drain valve; the pivot adopts a blowout-proof protection structure to effectively prevent leakage; bearings with a low friction coefficient minimize the torque, facilitating the opening and closing of the valve; the contact between the valve stem and the valve body ensures reliable performance of the grounding device, etc. It has advantages such as excellent performance, wide application range, and reasonable price.

Application Fields of Electric High-Pressure Flange Ball Valve

Nowadays, electric ball valves have been widely used in industries such as petroleum, natural gas, food, hydropower, electric power, water supply and drainage, heating, and metallurgy. Due to multiple advantages of electric ball valves—such as compact structure, small volume, large flow capacity, light weight, easy operation, and remote control capability—they are not only excellent products for throttling, shut-off, cutting, on-off, and flow diversion but also ideal products in flow regulation systems.

Product Features of Electric High-Pressure Flange Ball Valve

Low fluid resistance: Full-bore ball valves have almost no flow resistance.

A fire-resistant sealing ring is installed between the ball and the valve seat; even after the valve seat is burned out, the sealing function is still maintained.

Reliable sealing: It has two sealing surfaces, and the sealing surface material of the ball valve is plastic, which provides excellent sealing performance and can achieve tight sealing. It has also been used in vacuum systems.

Easy operation and long service life: Fast opening and closing—only a 90° rotation is required from full open to full close, facilitating remote control.

Convenient maintenance: The ball valve has a simple structure, and the sealing rings are generally movable, making disassembly and replacement relatively easy.

When fully open or fully closed, the sealing surfaces of the ball and valve seat are separated from the medium; the medium will not cause erosion to the valve's sealing surfaces when flowing through.

Wide application range: The nominal diameter ranges from a few millimeters to several meters, and it can be applied from high vacuum to high pressure conditions.

Due to the low friction during the opening and closing process of the ball valve, it can be used in media containing suspended solid particles.

Electric ball valves support remote centralized control and can meet the requirements of computer programming control (needing to be equipped with IEV2/IEV3 series intelligent actuators).

Appendix: Intelligent Actuator Description

This intelligent actuator provides standard RS-485 and M-bus interfaces, supports the MODBUS RTU protocol, and can directly conduct network communication with the control system without DDC/PLC/DCS. It can record a large number of real-time operating parameters of the valve. In addition, it can provide wireless communication function, significantly reducing wiring costs.
