Domeloaded Pressure Regulators .exhibit minimal droop.
May 2, 2011 -
Used to control pressure of liquids and gases, RHPS series features domeloaded design that relies on pressurized chamber above elastomer diaphragm to operate regulator. Inlet pressures range to 5,800 psig, and regulated pressures spans include 1.4-29 psig, 0-1,000 psig, 0-2,900 psig, and 0-5,800 psig. Available for pipe sizes from ¼-4 in. with corresponding Cv values from 0.1-73, regulators use 316L stainless steel for body, dome, and trim.

Swagelok RHPS Series Domeloaded Pressure Regulators
SOLON, Ohio - Swagelok® RHPS series domeloaded pressure regulators permit high flows and exhibit less droop than spring-loaded designs in controlling the pressure of liquids and gases. 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 5800 psig (400 bar). Regulated pressures span 1.4 to 29 psig (0.10 to 2.0 bar), 0 to 1000 psig (0 to 70 bar), 0 to 2900 psig (0 to 200 bar), and 0 to 5800 psig (0 to 400 bar).
Swagelok domeloaded regulators are available for pipe sizes ranging from 1/4 to 4 in. with corresponding Cv values ranging from 0.1 to 73. End connections include NPT female, BSPP female, and ANSI and DIN flanges. Body, dome, and trim material for all models is 316L stainless steel. Operating temperatures range from -4 to 176° F (-20 to 80° C). Seal, O-ring, seat, and diaphragm material options include nitrile, EPDM, and fluorocarbon FKM. (Seat materials also include PCTFE and PEEK.)
Larger models, 1-1/2 in. and above, include an integral pilot regulator to keep the dome pressure constant. The dome can be energized by system pressure or an external pressure source. Special external feedback configurations which require no external power are available which permit even finer control of pressures. All models, regardless of size, include connections for installation of pressure gauges or other pressure measurement devices.
