Parker Needle Valves
Precision Needle Valve – MVI Series
Parker's MVI series is a cartridge-type metering valve that meters flow in both directions.
Parker's MVI cartridge-type needle valves are designed for installation in a precision-machined cavity made in the manifold of the machine and can be used in air, water & oil applications. These valves provide precise metering control and full shutoff of flow. An o-ring and backup ring installed on the cartridge fully isolate the inlet and outlet ports of the machined cavity from each other.
