Safety Valve
Back Pressure Regulating Valve





About The Product

A Back Pressure Regulating Valve is a self-operated control valve designed to maintain a constant upstream pressure by relieving excess pressure in the system. It ensures process stability and protects equipment from overpressure conditions. It is a crucial device in a tank blanketing system, designed to prevent catastrophic failure by maintaining safe and stable pressure conditions within the tank

In tank blanketing systems, maintaining a stable internal pressure is critical to ensure safety and product integrity. These systems often use an inert gas (commonly nitrogen) to create a protective blanket above the stored liquid, preventing contamination, oxidation, or the formation of flammable mixtures. The back pressure regulating valve plays a key role by preventing excessive pressure buildup inside the tank.
