Pressure Reducing Regulators

Pressure reducing regulators are designed to accept an inlet pressure (P1) and reduce this inlet pressure to a specific output (P2) pressure. The Burling Valve regulators can be configured to control the pressure of various gases and liquids accurately and repeatably. Ranging in sizes from 1/2" up to 6" flange mount, the Burling Valve pressure reducing regulators are available with dome-loaded, spring-loaded or mechanically piloted version.

Dimensions

Dome-Loaded Pressure Reducing Regulators

BD3

Pressure Reducing

The simplest dome-loaded pressure reducing regulator or 1:1 mimic valve. The loading signal essentially equals P2. Perfect for tank blanketing, steam control and many other applications.

BD4

Pressure Reducing with Return Spring

The same as the BD3 model except with a bottom return spring for proportional band control. Used when a "closed-loop" or feedback to regulator is generated. Excellent for use with electronic pilots.

Direct Acting Pressure Reducing Regulators

BS1

Pressure Reducing

The simplest spring-loaded (direct acting) pressure reducing regulator. Perfect for chemical and all simple process applications and industries. Most fluids and medias.

BS2

Pressure Reducing, Differential

Using a sealed differential chamber instead of the simple BS1 chamber, produces a differential pressure reducing valve. Perfect for seal pressurization applications, spring atomization and spray tower applications.
