Typical Flow Regulation (full open)
FCV7-10 - Flow Restrictor Valve
Needle
Up to 45 L/min (12 USgpm) • 210 bar (3000 psi)
Operation
This needle valve is a variable
orifice used to create a pressure
drop when flow passes from
port 1 to 2 or port 2 to 1.
Clockwise rotation of the adjust
screw de-creases the orifice size
Pressure Drop
Cartridge only
to completely closed and anti-
clockwise increases the orifice.
The setting can be locked using
the lock nut on the adjust screw
Features
Hardened and ground working
components. Cartridge
construction for maximum
mounting flexibility.
Description
This is a manually adjusted
cartridge type needle valve. With
fine control it is ideal for none
compensated speed control of
actuators or as a control orifice
in conjunction with a pressure
compensator Total shut off can
be achieved allowing the valve to
be used as a shut of valve.
