A liquid flow control valve helps regulate the flow of fluids by controlling pressure drop with the flow line. Valves are popular control devices for a process control system. An adjustable flow control valve helps to maintain composition, temperature, and pressure. The liquid flow control valve can also play a great role in keeping other process quantities.
While they are many in the market, every liquid flow control valve has its weaknesses and strengths for specific applications. You will get an adjustable flow control valve suitable to start or stop flow in the pipeline. In that case, the type of valve design with a low-pressure drop will be the best. You may pick a gate valve or ball liquid flow control valve for that specific use.
Do you seek to maintain the flow rate just into the process? Then, a globe adjustable flow control valve will be the best option to go for. When backflow is your concern, you will never go wrong by choosing a swing check valve. Once you install such a liquid flow control valve, it will help keep fluid flowing toward your preferred direction.
Liquid Flow Control Valve Design
A valve design is about picking the type of valve, body size, and trim that provides a specific lift function. In valve design, the pressure is formed by pumps. Then, it is debauched over the valve and system. The pressure created by the pump is always equal to the sum of the pressure drop throughout the liquid flow control valve and system.
For many flow systems, you will find a quadratic connection between pressure drop and the flow. The decline in pressure across the coolant flow control valve needs to be a third to a quarter of the total pressure drop within the normal operating conditions. If there is too much pressure drop, it's an indication that the valve uses a lot of pumping energy.
Any low-pressure drop, it will be a sign that the valve is oversize. That implies it can experience a hard time with the fine-tuned flow changes. So, such an adjustable flow control valve does not fit that application. You may use pumps with variable frequency drives. That way, you can regulate the flow rate of fluid and prevent a parasitic liquid flow control valve pressure drop.
Application of Flow Control Valves
You can use a liquid flow control valve in industries to regulate the rate of fluid flow. It's also vital in chemical bending and dilution.
Conclusion
Go for a liquid flow control valve if you want to control the fluid flow rate. You can rest assured to get accurate results. An adjustable flow control valve will enable you to eliminate any loss from excess flow or low flow of the monitoring fluid.
