PBM Sanitary Ball Valves - Tri-Canada

Adjust-O-Seal ® feature
n PBM valves provide bidirectional upstream sealing. Seats are compressed
tightly against the ball in the valve.
n Body bolts can be tightened to compensate for normal seat wear without
having to remove the valve from service.

Seals at
downstream seat
Seals at
upstream seat
Line pressure pushes ball downstream
in the ball-closed position, providing
sealing at the downstream seat. There
is no adjustment to compensate for
seat wear.
Valve body bolts compress valve seats
against the ball, providing bidirectional
sealing at the upstream seat. To
compensate for seat wear, body bolts
can be slightly tightened to re-compress
seats against ball.

This means on valves mounted vertically
like PBM’s angle stem flush tank valve,
the valve seats on the upstream seat,
thus allowing the body to be purged and
drained without process interruption.
