RHPS series domeloaded pressure regulators permit high flows and exhibit less droop than spring-loaded designs in controlling the pressure of liquids and gases, according to the the manufacturer. The domeloaded design relies on a pressurized chamber above an elastomer diaphragm in place of a spring to operate the regulator. Depending on regulator size and configuration, inlet pressures can range to 5,800 psig. Regulated pressures span 1.4 to 29 psig, 0 to 1,000 psig, 0 to 2,900 psig and 0 to 5,800 psig. Operating temperatures range from -4 to 176 degrees F.
