NV1-16 - Flow Restrictor Valve
Needle
151 L/min (40 USgpm) • 210 bar (3000 psi)
Operation
This needle valve is non-
pressure compensated. Flow is
controlled in the direction from
port 2 to port 1, from full flow
to tight shut-off, by turning the
adjustment feature clockwise.
The flow from port 1 to port 2
will be restricted.

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.
