The prosperity of the valve industry has been grown in many areas. In fact, there is a variety of valves.
With the various requirements, the ace valves are designed and manufactured with a wide variety of types, sizes, materials, temperature and pressure of work and actuating means and so on.
First, the structure is different. As is known a ball valve has a spherical closure element with a round hole or another shape in the middle and a gate valve comprises lifting and corner of abandonment.
And the number of maintenance ports varies. Valve spool has two ports, which is called an entrance and an exit. But a ball valve usually has two or more ports. However, referring to connections to ports, they would be the same, including the thread connection or welded flanges.
Secondly, a stop valve and a ball valve vary by the operation. Fluent, with a valve, is typically a manual operation. Such is the examination of the specific isolation of the flow.
Except in the manual operation, a ball valve is also capable of being driven by the electrical and pneumatic actuators.
