BS5 Back Pressure Regulator
Direct-Acting Back Pressure Regulator
Replacing the pressure reducing trim of our standard BS1 with back pressure trim produces our simplest direct acting back pressure regulator. The BS5 is excellent for pump discharge, filter and relief valve applications. It features a diaphragm for better response and/or more precise pressure or vacuum control than piston-type regulators.
- 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”.
