2 -Uses of Proportional Valve for Water

The proportional valve for water offers the change in the outgoing pressure or flow in the same ratio as it is in the input. For instance: if the input pressure is double, then the outgoing pressure must be double. Proportional control valve are interconnected with the output of one to the output of the other. Most of the pressure control valves are programmable with onboard diagnostics, making them highly suited for industrial systems. This article will discuss the uses of a proportional valve for water and other useful information. 

What is a Proportional Valve – How They Work

Proportional Valve for Water

The proportional valve for water is said to be a valve used to control the flow rate of the fluids by varying the size of the flow passage by the restrictor. The regulated rate of flow manages the parameters that affect the process in the system. Weight, humidity, thickness, ph, density, PH & viscosity are some of its minor parameters. The proportional valve uses the solenoid as the actuator for positioning the variable valve in the automated water proportioning valve. 

The direct-operated two-way standard proportional works the same as the direct-operated solenoid valve with a difference in the former operating via the range of valve positioning. In the directly operated proportional valve, the plunger is the restrictor. 

How Do I Select a Proportional Valve For Water

Below are some of the basic considerations that you need to keep in mind while choosing the water proportional valve:

  • What is being controlled with the proportional valve for water? Pressure, flow, or is there another characteristic that is involved?
  • What range that it requires, and at what range of flow rates?
  • What is the likely operating temperature that the proportional valve regulator will experience?
  • Other environmental considerations, like wet, dirty, or explosive applications?
  • Is the process static, step-by-step, or dynamic; this dictates the response time and hysteresis performance.
  • The last consideration is the cost that will help you decide on purchasing a proportional regulator.

Typical Applications of a Proportional Valve for Water

Proportional valves are particularly perfect for applications where the outgoing pressure and flow of fluids are required to vary during the process or from one process to the next. They’re dependable, cost-effective, and very good at delivering fast response and consistent control, especially when pressure fluctuations. Proportional valves can help you reduce cycle times by quickly achieving stable pressure.

Some of the typical applications are:


Bottle Filling

The proportional valve for water maintains a stable pressure for the fluids in the filling reservoir, irrespective of the level of liquids. The pressure sensor of the reservoir provides feedback to the proportional control valve to ensure a constant volume of liquid that is transferred to a bottle at a given time.

Furnace Control

The proportional valve regulates the gas supply; a differential temperature signal is used as feedback to shut down the gas flow when the desired temperature is reached.

Leak Testing

At a defined profile, the proportional valve can apply increasing pressure to a given test piece.
