Description

The volume booster amplifies the volume at a 1 to 1 ratio of pilot pressure to outlet pressure. The booster is a rugged precision instrument with key Features providing reliable, efficient and stable operation. Very low deadband between the operation of the supply valve and exhaust valve providing provides excellent pressure control. High capacity exhaust valve provides efficient dynamic reverse flow characteristics. Pressure balanced supply valve prevents changes in control characteristics when supply pressure changes. Damped diaphragm control chamber provides stable operation and protects valves from damaging oscillation under high flow conditions.
