LPRD20, 25, 30, 40 Series Regulator
Brand: Swagelok CompanyThese 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 (piston in RD2 series), 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, and the LPRD series are low-pressure, high-accuracy versions of the RD series regulators. The RA series regulators are air-loaded regulators.
