[Valve knowledge] Smithing Flange High Pressure Ball Valve Features and Application Range

The main features of high-pressure ball valves are compact structure, reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are always in a closed state and are not easily eroded by the medium. They are easy to operate and maintain. They are suitable for general applications such as water, solvents, acids, and natural gas. Working medium, but also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., and are widely used in various industries. The ball valve body can be integral or combined.

Features:

1. Among various valves, the ball valve has the smallest flow resistance. When the full-diameter ball valve is opened, the ball channel, valve body channel and connecting pipe diameter are equal and become one diameter, and the medium can flow through almost without loss.

2. The ball valve can be fully closed and fully opened by rotating 90°, opening and closing quickly. Compared with gate valves and globe valves of the same specifications, ball valves are small in size and light in weight, making them easy to install in pipelines.

3.On/off indication of forged flange high-pressure ball valve: The ball, valve stem, and handle are the moving parts of the valve and are an assembly unit. The head of the valve stem adopts a square structure, and it is easy to tell whether the valve is in the open or closed position from the position of the handle. When the flat side of the handle or valve stem is parallel to the axis of the pipe, the valve is in the open position;

4. Valve locking device: In order to prevent misoperation of the valve, the valve can be locked with a lock at the fully open and fully closed positions, especially for valves installed in the field or when the process flow does not allow the valve to be opened or closed. In order to prevent other personnel from making mistakes When operating a valve, it is important to lock the valve position. Therefore, according to the user's needs, when designing the valve, the locking hole positioning piece can meet the user's process requirements.

Application:

Smithing flange high-pressure ball valves are mainly used in various high-pressure medium transportation pipelines in chemical, metallurgical, petroleum, pharmaceutical and other industries. Applicable temperature: -196~450℃; driving mode: manual, pneumatic, electric, hydraulic, turbine, etc. ; Nominal diameter: 1/2" ~ 12"; Nominal pressure: 150LB ~ 1500LB; Applicable media: water, gas, oil, natural gas and acid-base corrosive media.
