Type MR105 direct-operated pressure reducing regulator is a high capacity multi-purpose regulator designed to provide fast and economical pressure control for various applications and is suitable for different flow media such as liquid, air, and gas. Type MR105 is ideal for applications where speed of response is critical, minimum differential pressure is a concern, or the process fluid is not free of impurities. Typical applications include lube oil, cooling water and pump bypass regulators.
