Data Sheet

Any substance that is capable of flowing or of
being poured is known as a liquid. One of the
most common liquids that we come in contact
with on a daily basis is water. Other liquids
include detergents, paints, aqueous chemicals,
fuels, and oil.
Liquids differ from gases as they are
incompressible and viscous. Because of these
characteristics, special consideration must be
given when selecting a regulator. All regulator
parts that touch the fluid must be compatible
with the fluid. The regulator design may require
modifications or special materials.

Bulletin No. 71.4:MR108
The Type MR108 regulators are direct-operated, backpressure, high-capacity, multi-
purpose regulators. It provides a simple, reliable, and economical backpressure control
in multi-purpose applications suitable for different flow media including liquid, air, and
gas. Applications include lube oil systems and any application where speed of response is
critical, minimum differential pressure is a requirement, or fluid is not free of impurities.
