Different Types of Gate Valves that Exist in the Market

Gate valves are the commonly used valves to open and close the path of a fluid from straight line mediums. A gate valve may find applications in a number of areas. For example, these valves can be used for the purpose of irrigation and also in various chemical plants to control the flow of different types of fluids.

There are many ways to classify gate valves. In fact, these valves exist in a variety of designs to offer suitable functionality for different applications. Each type of gate valves is popular for its acceptance in different fields. As a valve dealer, you must offer different types of gate valves to the customers. The following discussion will help you learn about the most popular types in detail.

Gate Valves in Different Materials

There are many popular materials that are used for manufacturing gate valves. Those made of bronze and brass are among the popular varieties. Various forms of iron, including cast iron and ductile iron, too are used for China cast steel valve manufacturing. Among the different varieties of steel, stainless steel, forged steel, cast carbon steel and alloy steel are the quality materials for durable gate valves. Finally, there are valves made of gun metal that you can obtain from different manufacturers.

Rising and Non Rising Stem Gate Valves

The most important way to classify gate valves is on the basis of the behavior of the stem attached to these valves. A rising stem gate valve is one in which the stem rises when the valve is rotated to open. However, this type of valve may not work when there is less vertical space. For example, rising stem valves are not suitable for underground operations. Non rising stem gate valves are used in such situations. Stems don t rise during the operation of these valves.

Gate Valves with Different Bonnet Styles

Gate valve can also be classified on the basis of the type of bonnet they have. Screw-in bonnet style gate valve are small in size and used for simple applications. On the other hand, high pressure applications make use of China cast steel valve with bolted bonnets. For extremely high pressure applications, the use of gate valves with pressure seal bonnet is popular for offering high safety. A gate valve with union style bonnet is another option and used for applications where regular inspection is required.

Wedge and Parallel Gate Valves

Depending upon the shape that the gate valve faces form, these valves can be divided into wedge and parallel gate valves. Wedge gate valves can be further classified into single gate type, dual gate type and flexible gate type. Parallel gate valves too can be classified into single and double plate types.

Another type of gas valves consists of those which regulate the flow of fluid. However, gate valves are rarely used for the regulation purposes due to the fear of damage. You must guide your customers about the safety and maintenance of gate valves to exhibit your expertise in these products. In order to obtain different gate valve models, you can find the listings of reputed China cast steel valve manufacturers at online business directories. http://www.valve-supplier.cn/4-API_600_cast_steel_valves.html
