Application
This Series can maintain a constant pressure upstream (back pressure) or downstream (pressure reducing). The back pressure unit is used to maintain pressure on separators, vessels or any location where constant pressure is vital. The pressure reducing version is suited on gas lift operations to protect surface equipment and to replace fixed orifice devices. The 8950 Series is available in a 316L stainless steel 2” body to CF8M specification.
