What is Double Regulating Valve? Uses and Working

Double Regulating Valve

Double regulating valves have skyrocketed in recent years, particularly in commercial and industrial settings. They are found in heating, ventilation, plumbing, and cooling systems, among other applications. However, many still need a clearer understanding of these valves and how they work. In this post, we’ll take you through what double regulating valves are, their uses and how they work.

What is Double Regulating Valve (DRV)?

A double regulating valve (DRV) is essentially a valve that performs two functions: regulating flow and measuring it. They are fitted with a differential pressure measurement device to regulate the flow of fluids in a pipeline system. The device ensures that the flow rate is maintained at the correct level, irrespective of fluctuations in pressure from other parts of the system. Consequently, double regulating valves offer better flow control than traditional valves. To put it simply, DRV controls the liquid flow rate in a pipeline system and measures the flow rate at the same time.

How Does Double Regulating Valve Work?

DRV works by regulating the velocity of the fluid or gas passing through a pipeline using the differential pressure measurement device. The device is positioned to detect the difference in pressure between the upstream and downstream sections of the valve. This pressure difference is used to control fluid flow within a given range. When the valve opens, the pressure differential changes in response to the flow rate. DRV calibrates this differential pressure to maintain the flow rate at the desired level.

Uses of Double Regulating Valve

DRV is synonymous with HVAC systems, but it’s also used in several other applications.   In general, applications include measuring any fluid flowing in a pipeline system. Double regulating valves are often used in the following areas – circulation control in heating systems, Chilled Water Systems, hot liquids, water-treatment plants, fuel distribution systems, swimming pools, fire suppression systems, and many more.

How to Use DRV

To use a DRV, first, determine the flow rate of the liquid or gas. The flow rate can be determined from the manufacturer’s specifications, or users can take a reading using a flow meter or measure the fluid’s duration to reach a certain point. Once the flow rate is determined, install the DRV or calibrate to maintain the correct flow rate. Typically, they are installed at the pump outlet and can be adjusted as necessary to ensure the flow rate is maintained at a constant level.

Why Use Double Regulating Valves?

Double regulating valves offer several benefits compared to traditional valves. They offer better flow control, meaning the flow rate can be maintained at a desirable level irrespective of fluctuations. DRV ensures that the fluid travels at a consistent speed, which leads to energy efficiency and reduces the risk of damage to the pipeline system. They are also known to be extremely reliable and easy to install.

Conclusion:

In conclusion, if you are looking for improved control of the flow of fluids in a pipeline system, consider double regulating valves. DRV has revolutionized the HVAC industry and several other applications. It offers advanced flow control, better reliability, increased energy efficiency, and several other benefits. DRV is wise for anyone who wants to maintain consistent flow control in a pipeline system.
