Applications & Benefits

The three-piece body eases in-line maintenance, while the anti-blowout trunnion stem and Inconel® seat springs support dependable upstream and downstream sealing at pressure. Double block-and-bleed operation lets crews isolate and safely verify a zero-pressure condition for maintenance, and the firesafe stem packing with O-ring backup guards against leakage. With a direct-mount topworks pad for an actuator or gear operator, plus self-relieving or double-piston seat options, the KF suits oil & gas, pipeline, and process isolation where secure double block-and-bleed shutoff is required.
