Some of us may know industrial valves such as forged steel gate valve before, but only know little about them. Industrial valves are devices which are used to regulate liquids, gases, and slurries. The flow of liquids or gases is usually controlled with these valves. Today we will introduce valve components and the main types of valves in this article.
Different valves can vary greatly in size and design, but they have some same basic components.
The body of the valve makes parts together. The ends are created to connect to the pipe or equipment in the system and usually are butt or socket welded, threaded or flanged. The body is the first pressure boundary to come into connection with the surrounding environment and system media. The environment is a key consideration when choosing the body material.The bonnet will be the cover for the opening within the body. This is the second most key boundary of a pressure valve and is made from exactly the same material as one’s body. The bonnet could also support internal valve parts, such as the stem, disk, and actuator.
Trim is a term used for the replaceable internal parts like the disk, seat, stem, and sleeves utilized to guide the stem. The trim is responsible with the basic motions and flow control features with the valve.The disk and seat supply the capability for permitting and prohibiting fluid flow. The system is under full pressure in the event the disk is closed. The seat comes with a surface for the disk to seal too so that you can stop the flow. The valves could possibly have one or more seats based on the type. For example, a gate valve has two seats; one around the upstream side and the other around the downstream side. The design with the disk is usually where valves obtain name.
Gate valve is the most common products which used in our daily industries field. It is utilized mainly for blocking fluid flow and is less likely to be employed for flow regulation. A gate valve uses a plate-like barrier which might be lowered to the flow stream to stop the flow. Its operation is like that of a globe valve except the gate provides less flow restriction as compared to a globe-valve plug when the valve is within the fully opened position.
