Type 6100 aluminum and Type 6200 stainless steel large-flow-capacity volume boosters have a SIL 3 safety rating. These units, along with the larger Type 6500/6600 boosters, are well-suited for applications that require high flow capacity or remote pressure control. They typically are used to increase throttling speed of large-volume control valve actuators. When used in a safety system, the volume boosters are used in conjunction with a valve actuator to perform a safety‐related function. The greater air flow these large-flow-capacity units provide allows a valve to actuate more rapidly, which then allows a safety shut‐off system to reach a safe state more quickly.
