INTRODUCING THE BP-LF690...
The BP-LF690 is a piston-sensed low-flow back pressure regulator for gas or liquid applications. The gas version includes a thermoplastic seat, whilst the liquid version features metal-to-metal seating. In addition to Stainless Steel, it is available in a range of materials including Titanium, Vespel® and Hastelloy®.

The BP-LF690 accurately controls inlet pressure and vents excess pressure back via the threaded 1/2" NPT / BSP or 9/16" MP outlet port.
