The difference between hydraulic ball valves and ordinary ball valves

The difference between hydraulic ball valves and ordinary ball valves

1Structure

1. Hydraulic ball valve

Hydraulic ball valve includes a ball, a valve seat, and a ball sealing device. A control port is set on the ball to control the flow rate of the medium. The hydraulic ball valve also includes a hydraulic drive device for manipulating the rotation of the ball, indicating that the hydraulic ball valve is a type of ball valve driven by hydraulic pressure.

2. Ordinary ball valve

Ordinary ball valves also consist of spheres and valve seats, but do not include hydraulic drive devices.

 

2Purpose

1. Hydraulic ball valve

Hydraulic ball valves are usually used in complex working environments and situations with high fluid pressure, such as in fluid control systems in industries such as petrochemicals, metallurgy, and fertilizers.

2. Ordinary ball valve

Ordinary ball valves are used in situations where flow and pressure requirements are not too high, such as water supply and drainage pipelines, household water pipes, etc.

 

3Working principle

1. Hydraulic ball valve

Hydraulic ball valve drives the rotation of the ball through the rotational torque provided by the hydraulic cylinder, thereby achieving the goal of controlling fluid flow.

2. Ordinary ball valve

Ordinary ball valves use manual or electric methods to control the rotation of the ball, achieving the opening and closing of the fluid.

Overall, the differences between hydraulic ball valves and ordinary ball valves are mainly reflected in their structure, purpose, and working principle. Although hydraulic ball valves have complex structures, they can work under high pressure environments through hydraulic drive, making them widely used in some special industries. Ordinary ball valves are usually used in some relatively simple situations, such as household water pipes. Readers can choose the appropriate type of ball valve based on their industry and usage scenario.
