BSH10, 15 Series Piston Sensing Regulator

Brand: Swagelok Company

The BS series back-pressure regulators are suitable for most gases and liquids. 

The BS series regulators feature a choice of sensing types (diaphragm or piston), and seat and seal materials to accommodate a variety of pressure, temperature, and flow conditions. 

The BSH series regulators are high-pressure versions of the BS series regulators.
