Balance type! A single-stage pressure regulator that can be manufactured as a product certified by the Minister of Economy, Trade and Industry.
The "NPR-2 and NPR-3 series" are balanced single-stage pressure regulators designed for use with medium-sized gas supply units and assemblies. Additionally, the "NPR-2B-DS" and "NPR-2S-DS" feature stainless steel diaphragms. By adopting the NPR method (balanced structure), stable gas supply is possible, and 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. 【Features】 ■ Available in brass and stainless steel types ■ Optimal for gas supply with purity of 99.99% (brass) to 99.999% (stainless steel) ■ Flow direction can be produced with a left-side inlet (left high pressure) type For more details, please refer to the catalog or feel free to contact us.
