The BP-LF691 is a piston-sensed low-flow back pressure regulator for gas or liquid applications. As standard, the gas version includes a PEEK™ seat, whilst the liquid version features 316SS seating. Alternatively, other seats are available to suit your application including Titanium, Vespel® and Hastelloy®.
The BP-LF691 accurately controls inlet pressure and vents excess pressure back via the threaded 1/2″ NPT / BSP or 9/16″ MP outlet port.
