It is an air-operated (remote-controlled) pressure reducing valve that can vary the secondary pressure.
The air regulator "Super Precision Pressure Reducing Valve Air Relay RR Series" is an air-operated type pressure reducing valve that can vary the secondary side pressure based on the external pilot pressure input, unlike other pressure reducing valves. It utilizes a servo balance method that employs a rolling diaphragm and measuring capsule for pressure control, allowing for precise pressure adjustments. The RR series performs precise pressure relay control with an output change ratio of 1:1, enabling both positive and negative bias adjustments. For more details, please download the catalog.

basic information
【Features】 ○ An air-operated type pressure reducing valve that allows variable secondary side pressure through external pilot pressure input, unlike other pressure reducing valves. ○ Utilizes a servo balance method with a rolling diaphragm and measuring capsule for pressure control, enabling precise pressure adjustment. ○ The RR series features precise pressure relay control with an output change ratio of 1:1, allowing for positive and negative bias adjustments. ○ High precision control → Achieves high precision pneumatic control with a sensitivity of 0.1% F.S. and repeatability of ±0.1% F.S. ○ Excellent characteristics → Relief characteristics, pressure characteristics, and flow characteristics are exceptionally good. In particular, the minimum relief pressure (relief sensitivity) is outstanding at 0.03 kPa (theoretical calculation value), making it ideal for applications such as tension control and air balance. ○ Excellent starting stability → No need to readjust pressure even after long periods of inactivity. ○ Remote operation capability → Enables remote operation by using the air relay RR series. ● For more details, please contact us or download the catalog.
