Direct Acting Pressure Regulators
The BS-Series, direct acting pressure reducing (and back pressure) regulators can be used to control most industrial gases and liquids. A specific spring range is used to set pressure in the main process. This spring is adjustable within a range of force that equates to the range of desired pressure control.
BS1
Direct Acting Pressure Reducing Regulator
The simplest spring-loaded (or direct acting) regulator. The spring can be manually adjusted and will maintain a consistent P2 pressure.
BS2
Direct Acting Pressure Reducing Differential Regulator
Using a sealed differential chamber instead of the simpler BS1 chamber produces a differential pressure reducing valve. The BS2 is excellent for seal pressurization, spring atomization and spray tower applications.
BS5
Direct Acting Back Pressure Regulator
Replacing PRV trim with back pressure trim produces our simplest direct acting back pressure regulator. The BS5 is excellent for pump discharge, filter and relief valve applications.
BS8
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.
