Premier 2500A Series

Absolute Pressure, Single Stage, Diaphragm Sensed, Pressure Reducing Regulators

Premier 2500A Series regulators are single stage, diaphragm sensed, absolute pressure regulators.  They can be used to reduce supply pressures up to 3000 PSIG (206.84 bar) into a vacuum environment for sub-atmospheric pressure control. Premier 2500A Series regulators feature a stainless steel diffusion-resistant metal diaphragm, Cv 0.08, captured bonnet, inlet filter, and optional panel mount or bottom mount.
