BS (H) 4, 6, 8 Series Diaphragm Sensing Regulator
Brand: Swagelok CompanyThe 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, and the LBS series are low-pressure, high-accuracy versions of the BS series regulators.
Features- Threaded vent to monitor seal integrity
