Flow and level control technologies
Most fluid management applications combine a combination of flow monitoring, using sensors or switches, with valves to regulate the fluid flow. The fluid is often fed to and from tanks, containers or vats that require level sensing to ensure the process is running correctly.
Application ideas and more.
Below are sections containing a collection of use tools, guides and software to help you choose and use the right products for your application.
Most automated fluid process systems use solenoid valves to control the flow of fluid and there are various factors that must be considered when choosing a valve.
Solenoid valve sizing software
- Flow Coefficient - often called Kv
The Kv value is the metric measure for the flow of a valve. It is defined as; The volume flow in cubic meters per hour of water at a temperature of between 5° and 40° Celsius with a pressure drop across the valve of 1 bar. Many manufacturers quote flow coefficient within their datasheets and it can be an effective way of determining correct valve sizing.
- Chemical compatibility
Many process involve the handling of aggressive or caustic solutions and the materials within the valve must be compatibility to ensure a satisfactory working life of the valve.
These guides provide useful chemical compatibility guidance:

- Temperature range
If the media is hot - for example steam or hot oil, then the valve must have a suitable temperature rating.
This useful program created by Asco Joucomatic can help you calculate the Kv, the flow rate and the differential pressure of a valve or solenoid valve.
Pressure, length and temperature unit conversion integrated in the program. The program operates with Microsoft Excel software.
The information provided is not valve brand specific and the Kv value is a universally quoted valve characteristic.
