Parker metering valves are designed to provide accuracy and stability of flow rates in analytical, instrumentation and research applications. We offer a wide variety of options and assemblies. Our range includes pressure compensated flow control valves which extend to applications that demand constant flow with varying loads and pressures. These valves have the ability to work to high flow and high pressure specifications and can also operate under high temperatures. As a result, our metering valves are suitable for a variety of applications, including those that work in extreme environments, across many of the major industrial markets.
