Micro flow single seat control valve is a valve comprising a special needle valve plug which is tapered V-notches onto the periphery of the plug using CNC machines, and a cylindrical valve seat installed at the valve body, in which a gas or liquid flows through the gap between valve plug and valve seat to the passageway.
Micro flow control valves are often required in R&D facilities, technical laboratories, pilot plants and the like. To ensure their proper operation, such valves are purpose engineered and are certainly not just scaled-down versions of larger control valves.
