Types MR105 and MR108
Types MR105 and MR108 regulators provide fast, accurate,
and reliable pressure control for a variety of liquid and
gas applications. A simple and durable design is utilized
to withstand dirt and debris common in many liquid
applications without sticking and without compromising
shut-off performance. Applications include boiler feed
water, cooling water, lubrication oil, and any critical service
where the fluid is not free of impurities.
