Ball valve, the opening and closing part ball is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. Solenoid valves are electromagnetically controlled industrial equipment.

Ball valve is evolved from plug valve. From following feature of these two kinds of valve,we will conclude the difference between ball valve and diaphragm valve.Ball valve has the same 90° lift action, except that the plug body is a ball with a circular through hole or passage through its axis.

Ball valve: The ball valve is developed on the basis of the plug valve. Its opening and closing part is a ball, which is opened and closed by rotating the ball 90° around the axis of the valve stem. The ball valve is mainly used to cut, distribute and change the flow direction of the medium.

The difference of ball valve and globe valve is following:fluid resistance,structure,sealing face,operate type,maintain and applications field etc,ball have soft seated ball valve and metal seated ball valve,that’s depend on difference working conditions.

Compare ball valve with gate valve,it’s easy to find two kinds valve in the model and both of them are working in difference conditions for pipeline. Main differences are:advantages for working conditions,functions in the pipeline,structure,stroke of valve etc.

We will find following difference between ball valve and check valve:advantage of ball valve and check valve,structure,sealing performance,type etc.

The ball valve is composed of valve: body,ball,stem,sealing ring,packing, etc., and the butterfly valve is composed of valve: body,disc,stem,packing,etc. We will find following differences between ball valve and butterfly valve,and these are main points:body’s type,working conditions,operation,etc

​Hangna soft seated and metal seated valves are widely used in water & waste water treament,include:ball valve,butterfly valve,check valve,gate valve,globe valve,plug valve,Y strainer,valve's flanges and pipe fittings etc.

Hangna range of ball valve,butterfly valve,check valve,gate valve,globe valve,plug valve,Y strainer,valve's flanges and pipe fittings are used for Steam and Boiler's application.

The refining industry has undergone many changes, from the methods of processing to the length of time that they operate their process units. Hangna range of valves are used in refining industry with varied pressure & temperature ratings.
