BS1 Direct-Acting Pressure Reducing Regulator
Direct Acting Pressure Reducing Regulator
BS1 spring-loaded pressure regulators provide accurate pressure control of most industrial gases and liquids. Our simplest pressure reducing regulator design, this versatile direct-acting valve can handle many simple process applications. The spring can be manually adjusted and will maintain a consistent P2 pressure.
- 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”.
