Gas Pressure Regulators up to ANSI 600 and Main Valves with Electric Actuation Honeywell gas pressure regulators are designed to keep the outlet pressure of a gaseous medium constant in the mains and independent of disturbing influences such as inlet pressure and flow rate changes. Our ball valves are manufactured in high grade 316 stainless steel. 90 to 57 scfm at 125 psi to accommodate system requirements. When subjected to certain levels of increased outlet pressure, higher than the atmospheric pressure, or “back pressure” during discharge the performance of the liquid safety relief valve is subject to change. Shut off operating lines to the actuator. The main function is to protect mechanical equipment, most notably pumps, where back flow can damage the internal components. Automatically kicks back to neutral when cylinder completes stroke.
