RG4918 Pilot Operated Regulators | High Performance at Low Pressures
The RG4918 volume booster is a precision pneumatic valve designed for demanding applications requiring the ultimate in sensitivity, accuracy and flow capacity. The booster is designed with very low dead-band between the operation of the supply valve and exhaust valve allowing the RG4918 to achieve superb pressure control characteristics between forward flow and exhaust flow conditions. The high capacity exhaust valve is very useful in dynamic dual flow direction applications producing high reverse flow conditions.

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.
