Summarization of a flow control valve
A flow control valve is a device that is used to regulate the flow of fluid. It is also used to regulate the pressure of a liquid. Control valves usually respond to signals. The signals are produced by independent devices. Devices such as flowmeters and temperature gauges often work in combination with flow control mechanisms. The valves usually are pre-filters with positioners as well as actuators. Flow control valves can be used for appliances that require meter-in, meter-out or bleed-off.
Flow control valves are also operated hydraulically. They maintain a preset flow rate. Whilst limiting the flow at the same time. The maximum flow rate is maintained regardless of the upstream or the downstream pressure. The main valve position is controlled by a pilot valve which is adjustable. This valve senses the pressure of fluid across the opening plate.
In order to maintain changes in the flow, the pilot valve repositions itself and serves the purpose.
Features of a flow control valve
The flow control valve is widely used in many industries. It is used to control and regulate the flow of many liquids. Some of the features of a flow control valve are-
- It maintains the flow. The flow remains constant. This is because of changing pressure at inlet and outlet.
- It maintains the setting of flow with very little variation.
- The flow setting is adjustable.
- It allows the valve to be adjusted when the locked in the flow setting.
- The sub-plate anchored valve is maintained with the reverse flow valve.
- It has been designed to give continuous flow. The change of fluid temperature does not affect the flow rate.
- The construction of valve is very tough and sturdy.
- The valve is easy to fit.
Flow control valves are known to work with hydraulic actuators known as ACV i.e. Automatic Control Valves. ACVs do not require any power source. It means the pressure of the fluid is enough for opening or closing them.
Usage of flow control valves
Flow control valves are used by various companies and factories in an array of applications. Any form of liquid can be transferred via flow control valves - the valve is typically used to start, stop and throttle. This ensures the safety and efficiency of any process system.
The valves are required in many parts of mechanical factories, water systems in offices or for gasoline in automobiles. The valves are used in pipes to transfer gas and oil. This is the most cost- effective method to transport liquids and gasses. The flow control valves are also used in food and beverage industry, bio-pharm factories and marine enterprises.
