Description
The RS series pressure-reducing regulators are suitable for most gases and liquids.
The RS series regulators feature various poppet designs, a choice of sensing types (diaphragm or piston), and seat and seal materials to accommodate a variety of pressure, temperature, and flow conditions.
The RS series regulators are available in sizes from 1/4 to 2 in. with a choice of threaded or flange end connections.
The RSH series regulators are a high-pressure version of the RS series regulators, and the LRS and LPRS series are low pressure, high-accuracy versions of the RS series regulators.
The RS series regulators are available with many options, including a variety of gauge connection configurations, self venting, internal filter, external feedback, antitamper, special cleaning to ASTM G93 Level C, and NACE MR0175/ ISO 15156-compliant models.
