FC12-20 Screw-in cartridge style flow control cartridge valve is used for variable orifice control in order keep the limited hydraulic fluid rate. The FC12-20 flow cartridge valve controls the flow passage from 2 port to 1 port with full open at counterclockwise rotation adjustment.

FC12-20 Cartridge Flow valve operates like check when the fluid flows back, it stops the flow as check valve, it is open when the fluid flows from 1 port to 2 ports when the spring pushed to open by sufficient pressure on the needle seat.

FC12-20 Screw-in cartridge style flow control cartridge valve is the hydraulic flow control cartridge connection type valve, it controls the flow by changing the section size of flow cross chamber in valve. The cartridge flow valve combines the throttle and check function together, which not only controls the flow rate but also blocks one way flow in the converse direction. The flow check valve is also installed in return pipe line of the hydraulic systems to establish a backpressure. Back pressure is help a hydraulic system to work correctly, retain a certain pressure in the low pressure spot, to prevent cavitation, suction air or other irregularities in the implementation of the mechanism of occurrence created by a pump,

Finotek manufactures hydraulic manual cartridge flow valve in high quality standard, with the characteristics of precisely pressure adjustment and easily turning the knob under higher pressure, the key parts of throttle piston is hardened treatment for long terms of service.
