BS8 Positive Differential Back Pressure Regulator

BS8 Positive Differential Back Pressure Regulator

Direct Acting Positive Differential Back Pressure Regulator

By using a positive bias on the spring in compression with back pressure trim, we are able to product a positive differential back pressure regulator. The BS8 features a diaphragm for better response and/or more precise pressure or vacuum control than piston-type regulator.

  • Large CVs
  • Easy inline maintenance
  • Wide variety of body and wetted materials

All Burling Valve regulators are non-relieving. This direct-acting series thrives in the oil & gas and petrochemical industries. These heavy-duty quality casted valves offer 1/2″ to 2” threaded ports and flange options from 1/2” to 8”.
