Types MR105 and MR108 High capacity industrial regulators. TYPE MR108 LOW-PRESSURE ACTUATOR NEW TYPE MR105 HIGH-PRESSURE ACTUATOR 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. Product advantages: •  Available constructions to meet NACE MR0175-2003    and NACE MR0103 requirements for Sour Gas    Service Capability •  ANSI/FCI 70-3-2004 Class VI Shutoff •  Large Flow •  Travel indicator for Type MR105 •  Fast Response •  Multiple end connection options •  Suitable for High-Temperature Applications    up to 250°F / 121°C Features: Actuator Type and Maximum Outlet and Emergency Casing Pressures: Low-Pressure Actuator: 70 psig / 4,8 bar High-Pressure Actuator: 400 psig / 27,6 bar(1) Outlet Pressure Ranges: 5 to 300 psig / 0,35 to 20,7 bar(2) Temperature Capabilities: Nitrile (NBR): -20° to 180°F / -29° to 82°C Fluorocarbon (FKM): 20° to 250°F / -7° to 121°C Downstream Control Line Connection Size: 1/2 NPT Maximum Pressure Over Setpoint to Avoid Internal Parts Damage: Low-Pressure Actuator: 20 psig / 1,4 bar High-Pressure Actuator: 120 psig / 8,3 bar 1.
