The SPF Series Flow Control Valves meter flow of air or oil in one direction and allow free flow in the reverse direction. SPF Series valves are manufactured with a two step needle. Fine metering is accomplished over the initial adjustment turns and nominal metering is provided over the remaining turns. Once the desired flow is selected, a set screw can be tightened to maintain the setting. These valves are available with NPTF ports in 1/8", 1/4", 3/8" and 1/2" sizes.
