Becker AB Series

When conditions allow discharge to pressure system only part of the time, install an AB-Control for automatic switching that temporarily permits atmospheric bleed. The AB-Control will maintain adequate differential pressure between Supply Gas pressure and Discharge pressure to operate the control valve actuator and the primary control instrumentation device. The AB-Control is not applicable when the primary control instrumentation device discharges to atmosphere.

• The AB-Control allows the user to safely minimize atmospheric bleed gas emissions while maintaining safe operation of the control valve regulator.
• Once properly adjusted, the AB-Control functions automatically.

• Simple construction for years of maintenance free operation

• Can be easily retrofit to existing control applications bleeding downstream

• Comes factory adjusted

Features:

• Rugged anodized aircraft aluminum and stainless steel construction provides ultimate reliability and accuracy without affecting normal operation of control instrumentation

• Setpoint can be set up to 600 psi differential

• Supply pressure up to 600 psig

• Compatibility with all Becker control instrumentation

• Stainless steel option available

• The AB-Control is utilized only in instances when supply gas pressure and/or discharge pressure may vary such that adequate �effective power gas� may not be available.
• The AB-Control is not applicable when the primary control instrumentation device discharges to atmosphere.

The AB-Control may be utilized with all Becker primary control instrumentation devices that discharge bleed gas to a pressure system.

The AB-Control may be utilized with the following Becker instrumentation:

• All Becker VRP-Series Pilots
• All Becker HPP-Series Positioners
