RS (H) 4, 6, 8 Diaphragm Sensing Regulator

Brand: Swagelok Company
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 , and seat and seal materials to accommodate a variety of pressure, temperature, and flow conditions.

The RSH series regulators are a high-pressure version of the RS series regulators.
