The Series ER servo valve is Master Pneumatic’s latest
product using closed loop control technology. It in cor -
po rates many important standard features.
Standard fl ow rate of the valve is typically one scfm maxi
mum. When used with a volume booster a fl ow rate in
excess of 1,000 scfm can be achieved.
