Turn to Swagelok when controlling pressure is essential to safe, efficient operation at your facility. We have the right combination of regulators to maintain pressure and minimize droop over a wide range of pressures and flows. At Swagelok Cambridge our regulator expert understands the pressures related to reducing costs and demanding lead times that customers face today. Let our team be your partner for the selection and assembly of common regulator configuration.
Swagelok RHPS series regulators provide a variety of options including spring-loaded and dome-loaded for both pressure-reducing and back-pressure regulator models, as well as specialty regulators specifically designed for pharmaceutical applications. All possess FDA / USP Class VI compliant EPDM seals.
