The structure of piston check valve is similar to globe valve,but these two kinds of have have some differences between globe valve and piston check valve,the operation of piston check valve is flow automatic,the globe valve have a handwheel to operating,this is most difference of valve’s type.
The needle valve is evolved from the globe valve, sometimes called the needle valve globe valve. The specific difference is that the disc of the needle valve is a sharp cone, which is inserted into the valve seat like a needle. The needle valve is a kind of valve that can be precisely adjusted. For
Compared with the gate valve, the globe valve has the advantages of simple structure, good sealing performance and convenient manufacturing and maintenance; The gate valve and the globe valve are full-open and fully-closed valves.
The isolation valve belongs to the on/off type valve, which is only in the open or closed state. Isolation valve is basically has a requirement for the leak level. Relatively speaking, the safety requirements are higher than that of the on/off valve, and some parts have higher requirements.
What is the difference between a butterfly valve and a globe valve? To put it simply: the globe valve has better adjustment performance than the butterfly valve, and the butterfly valve has poor regulation performance.
Compared with the gate valve, the globe valve has the advantages of simple structure, good sealing performance and convenient manufacturing and maintenance; the disadvantage is that the liquid resistance is large, and the opening and closing forces are large.
Butterfly valves and gate valves are indispensable components in fluid pipelines, and they have a very wide range of applications. There is a difference in the function of the two, but the butterfly valve and the gate valve are more different. The most difference is appearance.
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.
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.
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.
