Troubleshooting Valve Flow Problems

Through normal wear and tear or improper installation, fluid flow valves can quickly begin to leak or provide improper fluid pressure. A few troubleshooting techniques can help you find the valve problem for either an effective repair or the proper replacement.

Incorrect Valve Size May Cause Damage

If the flow of liquid in your system isn't coming out quickly enough or is flowing at the wrong pressure, consider how the valve and connecting lines or pipes are connected.

Both the pipe and the valve have a specific measurement or gauge that needs to match the pressure needs. Having a pipe or line that is too small for the valve will result in an increased pressure, which can be bad for many fluids.

If pressure is too high from having a smaller line connected, some material may become frothy or completely change composition. For products such as wine, where the flavor and texture can change through excessive force, this can be highly damaging for a large volume of the liquid.

The improper pressure can also be damaging to the equipment. Pipes made of plastic-like materials may swell and burst easily, or the insides of the pipe may wear into a thin layer from the excessive force. If you only have a specific gauge of hose available, you may need a more specific industry valve to match it. Changing valves can be a lot easier than replacing entire hose supplies.

Power Intake Valves

By default, valves rely on the pressure inside their container to release their contents. There are times when you may want a specific, consistent pressure for releasing the contents.

Soft serve ice cream, for example, requires a very specific release of the product inside. Soft serve is generally held under some sort of pressure, but it isn't enough to release the ice cream to a satisfying, uniform effect.

The valve used to release the ice cream is equipped with a motor designed for food-grade processing. When the button is pressed, the motor starts and pumps in a specific amount of ice cream per rotation. As soft serve ice cream is thick, the motor needs to be resilient against the materials used in the product and able to force the thickness through without interruption.

The type of material matters, with traits such as viscosity, temperature, corrosive potential and many others making a huge difference. If your product needs to be pumped out at a similar pressure, make sure to consult an industrial valve specialist, such as Van Valve Service Centre & Sales Ltd, to find out what kind of speed and gauge your powered valve needs to be.
