What are the types of valves that can be used in various devices?
Valves are identified as a device or tool that moves between two pipes and can stop the flow of fluids in the pipe. Valves also have the capacity to change the direction of the flow of the fluid. Some valves, like a globe or a float valve, have additional features like controlling the flow, pressure and direction of the valve in the system. Here are some valves that can be used in a plethora of devices!
The linear-motioned globe valve
A globe valve functions in a linear motion and is designed to regulate the flow of the fluid while also controlling the start and stop of the action of the flow. A conventional globe valve can also be utilised for the purposes of throttling and isolation in the device. Globe valves are available in three designs: Tee Pattern, Angle Pattern and Wye Pattern. A Tee pattern globe valve is designed with a Z-shaped diaphragm. The horizontal design of the valve enables the stem and disk to travel perpendicular to the horizontal line. This design is thus used in devices that require the lowest coefficient of flow and higher pressure drop. This design of globe valve is therefore used for severe throttling services. Angle pattern globe valve is a modification of the Tee pattern and ends at a ninety-degree angle. Wye Pattern Globe valves are used for the high-pressure drop, and the seat and stem are angled at forty-five degrees.
The regulating flow of the float valve
Float valves are installed in liquid tanks to regulate the flow of liquid in them. These valves fill the level of the tanks and control the flow of the liquids in the tank. The valve is then opened or closed by the lever attached to this valve. A float valve includes float balls and connectors that are used in innumerable industries. The components are designed and combine temperature, pressure and corrosivity as per industry standards. As the float valve is most likely to deal with corrosive liquid, thus, it is developed mostly with stainless steel. Stainless steel is known to render excessive corrosion resistance. Liquid level control is another factor that determines the use of valves in various industries. Stainless steel plays a major role in ensuring the safety and efficient overall functioning of these levels. Thus, it ensures that the device has a longer life as compared to valves developed with other materials.
The lightweight and compact butterfly valve
Butterfly valve helps devices to attain better flow control. It includes a metallic disk that rotates a quarter of a turn at one time. The disk is placed around a fixed-stem axis. The ninety-degree turns allow swift action control between the open and closed positions. These valves are lightweight and enable reasonable flow control in the most compact designs. Further, the design of a butterfly valve is extremely simple, and thus, it requires less maintenance. This valve, along with the globe and float valve, provides quick and efficient regulation and sealing of the flow in the equipment.
