How to select valves?

Valve selection

The primairy function of the valve directs you to select the right product with the right function, for flow control you will select a metering or needle valve and for selection of flow direction you will select a three-way or multiple-way ball valve.

Pressure and temperature limits have to be taken into account. In the product filter on Product Gauge you will find quickly the best compliant products.

The pressure limit of a product is depending on the temperature. The higher the temperature the lower the limit of pressure range, but be aware of minimum temperatures and the maximum pressure limit, this can be lower than the maximum pressure for the selected product.

Selection of the end connections and internal diameter (bore) provides the best match with flow and pressure capabilities. The CV value of the valve will give you good information of the flow capacity that can be handled through the valve.
