needle valve / manual / hydraulic / flow control
bidirectional, bypass, pressure-compensated
Max.: 190 l/min (50 us gal/min)
Min.: 3 l/min (1 us gal/min)
These valves are used for flow control and pressure compensation of hydraulic flows. Also, these valves are capable of uninterrupted pressure control of up to 345 bar, and 420 bar if periodically controlled. On the other hand, needle valves, pressure compensated flow regulators, and manual rotary valves are for checking the reverse flow. Other valve types include variable or fixed orifice valves, and HyPerformance™ HEC series.
