Fisher CS200 industrial Pressure reducing regulator
The CS200 Series regulators are typically installed on industrial and commercial applications. All constructions include internal pressure registration. Types CS200IR, CS205IR, and CS206IR contain an internal relief valve. Types CS200IN and CS205IN do not contain internal relief.
