DLM Valves side entry trunnion
mounted are available in full or reduced port.
Independent spring loaded seats are always in
contact with the ball to provide an effective
tight seal even at low pressure.
This feature permits the unique facility of double
block and bleed with the valve in either fully
open of closed position under line pressure.
Anti blow out stem design permits the replacement
of stem seal with the valve in fully closed position.
The stem seal integrity is achieved by the use
of three seals, two o-rings and a firesafe graphite
gasket. The graphite gasket can be replaced with
the valve under pressure.
