Type MR108 backpressure regulators are direct-operated, high-capacity, multi-purpose regulators. They are designed to handle pressures up to 400 psig / 27.6 bar and temperatures up to 250°F / 121°C. They provide reliable and economical control for different flow media like liquid, air, and gas. Application includes lube oil systems and any application where speed of response is critical, minimum differential pressure is a concern, or fluid is not free of impurities.
