Cartridge Flow Valve is designed with needle type of throttle rod and 3/4-16 male thread connection, hand wheel flow adjustable, cartridge style valve.

  • Max. operation pressure of cartridge flow valveup to 24Mpa/3480psi/240bar and mineral oil as media. Flow regulating from 0 to large rate up to 60L/min., strictly flow rate regulation of needle spool design.
  • The cartridge flow control valve is used for controlling the flow rate in hydraulic system, and usually used in the return cycle of hydraulic system to establish pressure by limiting the flow rate.
  • Cartridge Flow control valve manufactured by Finotek is reliable working in hydraulic system, we are using imported raw materials, low spring deformation. All of the key parts are hardened treatment largely increasing the service life and minimized inner leakage.
