NV1-10 - Flow Restrictor Valve
Needle
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
to completely closed and
anti-clockwise increases the
orifice. The setting can be locked
using the lock nut on the adjust
screw
Pressure Drop
Cartridge only
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.
