MRV2-16 - Flow Restrictor Valve
Semi-rotary
Up to 170 L/min (45 USgpm) • 210 bar (3000 psi)
Operation
This valve will increase or
decrease flow by changing the
variable orifice with the rotary
adjustment. Recommended flow
path is 2 to 1.
Pressure Drop Curves
Cartridge only
@ 5,5 bar (80 psi) pressure drop
Features
Hardened and ground working
components. Cartridge
construction for maximum
mounting flexibility. Flexible
mounting for the handle
position, detent available.

Description
This is a 2 way 2 position
manually operated semi
rotary restrictor screw in
cartridge valve. This can be
used in conjunction with
a compensator to give an
increase in flow in proportion
to the movement of the lever.
