Balance type! High flow regulator for devices that can be manufactured as Minister of Economy, Trade and Industry certified products.
The "NPR-4 and NPR-5 series" are large flow pressure regulators that have minimal outlet pressure fluctuations due to changes in primary side pressure. They are optimal when there is not much difference between the set pressure of the safety valve and the operating pressure. They have a proven track record in applications such as fire protection systems (where water for sprinklers is pushed out by N2 gas). They can be manufactured as products certified by the Minister of Economy, Trade and Industry. If used in high-pressure gas facilities, please choose certified products. The flow direction can be produced in a type with a left-side inlet (left high pressure). 【Lineup】 ■NPR-4B ■NPR-4S ■NPR-5B For more details, please refer to the catalog or feel free to contact us.
