Electro pneumatic regulator (nozzle flapper method) ER Series Variable controlling air pressure with electric signals ( to V DC / to ma DC) up to.mpa. Booster relay integrated and large flow rate. JIS symbol EXH Overview This electro pneumatic regulator ER series controls air pressure constantly with electric signals. This eliminates bothering works such as manual pressure adjustment, multistage pressure switching with combining several regulators and valves, etc. Changing input of voltage / current, the air pressure can be ideally controlled to achieve remote control or FA in pneumatic circuits. Features Compact Compact major dimensions with X. Space saving. High precision control Shown in linearity ±.%F.S. and hysteresis %F.S., accurate pneumatic control is enabled. Easy maintenance Fixed orifice and filter integrated. Wide adjusting range and span points can be adjusted within wide range.

pneumatic regulator (nozzle flapper method / large flow rate) ER Series A piezoelectric element and semiconductor pressure sensor are used to achieve precise air pressure control. Pressure monitor is also possible. JIS symbol EXH Refrigerating Desiccant High polymer membrane dryer Air filter Overview In electronic pneumatic regulator ER series, piezoelectric elements and semiconductor pressure sensors are used to control precise and constant air pressure with electric signals. Features New raw material Piezoelectric element (piezoelectric element) is used for nozzle flapper to improve resistance to mechanical vibration. Feedback control method Feedback control method with semiconductor pressure sensor and electronic circuit is used to achieve precise and outstanding temperature characteristics and stability. Common exhaust method Very small air consumption (/ of conventionals) and low operation cost. Common exhaust method eliminates environmental contaminations. Large flow rate type Max. flow rate is /min (standard state) for ER. Large relief flow also allows to control large load easily. Pressure monitor available. Pressure monitor terminal integrated.
