RG4918 | High Performance Volume Booster

• Very low dead-band between the operation of the supply valve and exhaust valve.
• High capacity exhaust valve provides efficient dynamic reverse flow.
• Large area diaphragms provide high accuracy, sensitivity and excellent low pressure performance – as low as 0-2 Inches of water full scale control.
• Soft seat supply and exhaust valves provide efficient leak free operation.
• Pressure balanced supply valve prevents changes in control characteristics.
• Damped diaphragm control chamber provides stable operation and protects valves from damaging oscillation under high flow conditions.
• Two accessory ports connected to the outlet chamber.
• Tapped exhaust port for exhaust or for incorporation of a silencer.
