Flow control valves control the volumetric rate of the fluid that flows through them. Generally, changing the size of the orifice is how the flow rate is set and adjusted. A tapered needle moving in and out of an orifice or opening and closing the gap inside a ball valve changes this rate.
How does a proportional flow control valve work?
A proportional control valve is a valve used to control fluid flow rate by varying the size of the flow passage via a restrictor. The regulated flow rate subsequently adjusts parameters affecting a process in a system, mainly level, pressure and temperature.
What are the three methods of applying flow control valves?
Meter in, meter out and bleed off are ways of applying flow control valves. A pressure compensated flow control valve is one which provides the desired flow rate regardless of changes in system pressure.

How do I know if my flow control valve is bad?
Symptoms of a Failing Check Valve For example, failing check valves will start to vibrate and even lose some internal parts when problems begin to arise. Other symptoms of check valve failure include reverse flow and excessive component wear and damage. Check valves will also emit noises as they start to break down.
Which valve is best for flow control?
ball valves
What does a flow control valve do?
A flow control valve adjusts and controls the volume flow of air within a pneumatic system. They can often be used to adjust the speed of operation of an actuator.
Can you control flow with a butterfly valve?
Unlike gate valves, butterfly valves can be used for throttling or regulating flow as well as in the full open and fully closed position. The pressure loss through a butterfly valve is small in comparison with the gate valve. The L/D ratio for this type of valve is approximately one-third of that of a gate valve.
What does the flow control valve do?
A flow control valve adjusts and controls the volume flow of air within a pneumatic system. They can often be used to adjust the speed of operation of an actuator. They should not be confused with pressure controllers, or regulators.
What are the three types of valve control?
