RFL
lined plug valves' 6" and above are offered with
Gear operation. The more flexible, reliable and easy to
operate valves with less torque is our specialty. The
lining, locked by grooves allows the valves to be used
on high vacuum and pressure applications without lining
collapse, shrinkage and blowout.
RFL
lined plug valves are virtually unaffected by changes
in processing temperature or chemical concentration. Valves
can be used in all corrosive fluids.
External
body of the valve is coated with corrosion-resistant coating
