How does an air flow control valve work?
Independently control the speed of airflow in two directions. These valves regulate the speed of airflow as it enters or exits equipment, and are often used to control the extension and retraction speed of an air cylinder at the same time.
What is the purpose of flow control valve?
A very common function of flow control valves is to control the speed of cylinders and air motors. The speed of cylinders or air motors depends on the amount of air, which can be controlled by flow control valves.
How do you control water flow?
A valve in plumbing is a device which is used to control the passage and flow of liquid or water from one place to another, usually through the channel or pipe. There are several types of valves that are used depending upon the application.
What is the principle of control valve?
Control valves automatically regulate pressure and/or flow rate, and are available for any pressure. The valve modulates flow through movement of a valve plug in relation to the port(s) located within the valve body. The valve plug is attached to a valve stem, which, in turn, is connected to the actuator.
Can a ball valve regulate flow?
The main difference between these two types is the way they close. A globe valve uses a plug (stem) that closes against the flow, and a ball valve has a gate (ball) that closes across the flow. Globe valves are good for regulating flow, whereas ball valves are better for on/off control without pressure drop.
Does a gate valve reduce pressure?
Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened enabling gate valves to offer straightway flow with very little pressure drop.
What is the difference between gate and ball valve?
What is the difference between gate valve and ball valve? The main difference is in the operation. A gate valve moves a solid disk up and down to open/close the orifice. A ball valve rotates a ball (the orifice) with a bore in it 90 degrees to open/close the valve.
