*1 (-B): Provides one-dimensional pressure adjustment (back pressure type). *2 For the (-B) type, only 10 to 500 kPa is supported. *3 For the (-B) type, up to 550 kPa (G).
* Pressure values written within square brackets [ ] are for reference only. NOTE: MO: Metal seal, normally open; RO: Rubber seal, normally open; B: Supports one-dimensional pressure adjustment (back pressure type).
* Internal surface polishing is available for metal seal type models. (A): Absolute pressure; (G): Gauge pressure; (d): Differential pressure
* LM is a symbol indicating gas flow rate (L/min at 25°C, 101.3 kPa).
