High-Accuracy Pressure-Regulating Valves for Steam

For Use With: Steam
Temperature Range: 40° to 450° F

Control steam line pressure with ±1 psi accuracy. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have a cast iron body that absorbs vibration from pressure changes to reduce wear and noise in your pipeline. They meet ANSI/FCI 70-2 Class IV for tight shut-off (max. leakage rate of 0.01%). Install 1/4 NPT male pipe (not included) between the control valve and your downstream steam line.

Repair kits (sold separately) include replacement seals, diaphragm, spring, and spring assembly.
