NV10-20 Hydraulic flow control cartridge valve is needle type, 7/8-14UNF screw, flow adjustable valve, used for controlling the flow rate in hydraulic system. There are hand wheel adjustment and hexagon socket head for optional, usually the hydraulic flow control cartridge valve is equipped for establishing back pressure in hydraulic system.

  • Max. pressure operation for flow up to 24Mpa/3480psi/240bar. Flow regulating range from zero to large flow rate, up to 56L/min., strictly flow rate regulation of needle spool design.
  • Two port hydraulic flow control cartridge valve, full flow adjustment used in main piping or to meter in or out flow controlling systems. The valve is designed to pilot flow in hydraulic systems, and easily to utilize Finotek cavity.
  • Needle throttle type from flow closed to open full in easily turns, small leakage rate while closed the hydraulic flow control cartridge valve.

NV10-20 Screw-in cartridge style flow control cartridge valve is usually mounted on the backup line in hydraulic circuit to keep the flow stable, to vanish some air shock in the pipe of hydraulic circuit.
