Description
These pressure-reducing, dome-loaded and air-loaded regulators are suitable for most gases and liquids, including acids and oils.
These regulators feature various poppet designs, a pressure-sensing diaphragm, and a choice of seat and seal materials to accommodate a variety of pressure, temperature, and flow conditions.
The RDH series regulators are high-pressure versions of the RD series regulators.
