Application
The 8150 Series maintains constant pressure upstream (back pressure) or downstream (pressure reducing) of the valve. The back pressure valve is used to keep a preset pressure on separators, vessels or any line where a constant pressure is critical. The pressure reducing valve limits the pressure downstream of the valve to protect equipment or instruments from higher pressure.
