WebParker flow control valves are designed to regulate the flow rate and pressure of media through a pipeline. Flow control valves are essential for optimising system performance and relying on a flow passage or port with a variable flow area. The range includes pneumatic and hydraulic control valves which are designed to cope with high flow rate …

The valve flow coefficient, or flow rate, is the rate at which media flows through the valve, and how much the pressure of the flow changes (drops) across the valve. The state and viscosity of the media will have an effect on flow rate, as will the valve size, type and diameter of the pipe connections. The flow rate value … See more While knowing the pipe connection size and orifice diameter is necessary for valve sizing, calculating the media flow rate and pressure drop across the valve will give you more accurate sizing information.
