Indeed, industrial valve manufacturers have made great contributions to the development of the modern industry.
Valves, as a significant mechanical part, play a crucial role in both industrial processes and everyday life. And, there is a large variety of valves available. All such types are manufactured to obstruct pipes or passages of liquids and gases whether wholly or partially to control the flow rate as required.
The majority of the mechanical valves function for the oil industry, mining industry, gas, water, and sewage as well. They are like tiny knobs that regulate the flow of fluids as well as cut off supply completely when needed.
Whether made up of plastic or metal, valves can be controlled either by handles, levers, pedals, and wheels or even automatically. Usually, the exterior parts, either metal or plastic, are called seats, while the inner part has plastic and rubber valves to effectively control the flow of fluids. Body, the interior part of the valve fits on the seat and controls the flow by opening and closing either partially or wholly depending upon the requirement of the flow rate.
Industrial valve is of different types, with each based on a different working principle and performing different functions.
Ball Valves
Ball the heart of the valve! It is a hollowed-out ball-shaped disk that fits inside a pipe. The valve starts and stops by the quarter-turn rotational motion of the disk. These valves are widely used to control the flow of fluids in industrial and commercial piping systems. The tight shut-off feature of these valves makes them specifically suited for flow control applications in high-pressure and high-temperature conditions. They are usually used in catalytic reforming, power, marine, petrochemical, and power industries. With carefully designed high pressure and high temperature, the ball valve can sustain temperatures as high as 400°F and elevated pressures up to 10,000 PSI.
Butterfly Valves
It’s another valve that uses the rotational motion with a thin disk in the flow path, instead of a ball-shaped unit. These valves are extremely lightweight, quick to use, and easily adaptable.
The butterfly valve is of three different types. The one is the high-performance butterfly valve, which is generally double eccentric in design, with pressure for up to 725 PSI. Another type is the resilient butterfly valve, which has a flexible rubber seat, with pressure for up to 232 PSI. And, finally, the last type would be the tricentric butterfly valve, which is normally designed with metal seating, with the valve working pressure for up to 1450 PSI.
Body Types
The two quite popular body styles in butterfly valve cover wafer and lug style. The wafer style usually features 2 to 3 holes in order to align and secure it with piping. Also, they can withstand twice the pressure of lug-style units. On the other hand, the lug-style valve functions with two sets of bolts, with each one attached to the related flanges.
Gate Valves
This is the type of valve that is used to open and close the flow of liquid from a straight-line medium. It is usually found on pipes in commercial buildings, factories, and even homes. These valves can be used in both directions, and are thus considered to be quite efficient in quickly controlling the flow of liquid.
Gate valve classification according to wedges
-
The flexible wedge valve
These valves include both one-piece and two-piece discs to alter the angle in between the seats.
-
Solid wedge valve
Its’ simple solid construction in a single piece makes it suitable for turbulent flow.
-
Split wedge valve
This type covers two pieces, positioned between the tapered seats in the body of the valve.
Classification according to stem
-
Rising stem valve
This valve includes a threaded shaft that can be rotated using a handwheel. The stem rises when the gate valve is opened and descends when the valve is closed.
-
Non-rising stem valve
In this type, the stem remains stationary and is used in underground tunnels and places where there is little or no space.
Globe Valves
As its name suggests, globe valves are spherical in shape. Their body is rounded and is made up of two distinct halves that are isolated by a disc that closes or opens. Unlike the other valves, globe ones offer greater precision than other types when it comes to regulating flow. It is composed of a baffle that splits the inside of the pipe, which is typically parallel to the pipe’s length. The baffle has a vacuum-packed opening that uses a flat plug or disc to break the flow inside the pipe. Also, it can be adjusted to raise or lower the flow and unlike other types, it does not leak as much. This feature makes it one of the most popular kinds of valves that are used across different applications.
Y-Strainers
Y-strainers typically offer lower resistance to liquid flow. As the name indicates, a Y-strainer is shaped like a “Y” and is manufactured to remove unwanted large particles from a liquid suspension in order to protect downstream equipment from being damaged. To the valve manufacturers, these units are available in a myriad of design and connection types that can match any industry or application.
Check Valves
Check valves are manufactured to allow the flow of fluid across a pipeline system in one direction only. These are reactive valves that get activated by the amount and pressure of the fluid present in the system environment. Typically, check valves are used in backflow prevention applications, food prevention environments, and wastewater treatment entities.
