Description
The FLS-R ball-screw design that operates by rolling friction rather than sliding friction. A bidirectional design with more flow direction flexibility and a longer service life. Seal diameters and seat bearing surfaces that maintain valve chamber pressure at a minimum. With a lower stem that counteracts top stem pressure push, you may reduce operating torque, limit body cavity pressure build-up, and provide position indication. A metal-to-metal stem backseat on both the balancing and valve operator stems enables for the replacement of either stem seal while the valve chamber is under pressure.The grease fitting port is used to check the backseat and to isolate the stem seal stuffing box from line pressure.
