And determining flow through a valve can be simple. This technical bulletin shows how flow can be estimated well enough to select a valve size—easily, and without Webthe valve introduces into the system as the valve is stroked. As the valve modulates to the closed position the system pressure drop shifts to the valve and reduces the flow in the system. The valve is very important to the operation of the system.
