Foreword
The IR3000 precision regulator (hereinafter referred to as the "product") has excellent relief
characteristics, and is constructed to always keep a constant pressure even if used with a reverse flow.
The product has the following features.
(1) A sensitivity of 0.2%F.S. at max is achieved by the nozzle and flapper design.
(IR3000: F.S.
Note) "F.S." is the abbreviation of full span.
(2) Various characteristics such as flow rate, pressure characteristics and repeatability are
improved compared to general regulators.
(3) Relief characteristics are improved.
(4) The adjustment range is as wide as general regulators, which is 0.01~0.8MPa.
