BMD beaumontmanufacturing PRP -R48L - B Regulator

Regulator Packages 
BMD’s pressure control package offering includes both 
pressure reducing and back pressure packages.  Packages 
are paired with one of BMD’s control valves (ordered 
separately), and include a pressure controller, two 
regulators, a drip pot with drain, and all the 
interconnec ng tubing.  Pressure controllers are 
available for high, medium, and low pressure se ngs. 
 Packages are factory assembled and tested to save me 
in the field. Other benefits include a drip pot drain to 
prevent clogging, and the use of two regulators for a two 
stage pressure cut to prevent regulator freeze up. 
Applications 
Back Pressure Packages: 
The Back Pressure Packages are used to hold a constant 
upstream pressure on a line or tank. A Back Pressure 
Package will typically be a reverse ac ng pressure 
controller paired with a direct ac ng (fail open) control 
valve. The pressure controller senses the upstream 
pressure and gives an output signal to the control valve 
actuator causing the control valve to open as the 
upstream pressure increases, and to close as it 
decreases. 
Pressure Reducing Packages: 
The Pressure Reducing Packages are used to regulate 
pressure downstream of the valve. A Pressure Reducing 
Package will typically be a reverse ac ng pressure 
controller paired with a reverse ac ng (fail closed) 
control valve. The pressure controller senses the 
downstream pressure and gives an output signal to the 
control valve actuator causing the control valve to open 
as the downstream pressure decreases and to close as 
the pressure increases.
