V83 Series Swing-Out Ball Valves
Pressure Rating up to 3000 psig (206 bar)

Catalog No. V83-3
Oct. 2009Features● Pressure and temperature compensation seat design.
● Swing-out design for fast and easy maintenance with the valve in-line.
● Chevron packing design.
● 2-way (on-off) valves with quarter-turn actuation.

Two flats on stem (10) and lever handle (13) indicate open or
closed position of the valve.

Built-in manual locking device (14) allows
locking the valve with a detent either inopen or closed position. You may also
apply a pad-lock to this device. Pad-lockhole: 8 mm (0.314 in.)141718Ball

Compensation seat design requires
no pressure to create a seal.
Under high pressure, seats react
on the ball movement for sealing
at upstream and downstream.

Factory Test
Every valve is tested with nitrogen @ 68.9 bar (1000 psig) for leakage at the seat to a maximum allowable leak rate of 0.1 SCCM.
Shell test with nitrogen @ 68.9 bar (1000 psig) is performed to a requirement of no detectable leakage with a liquid leak detector.
Shell test with water at 1.5 times the working pressure is performed on request with extra cost.

External Vent Options
The vent passage is isolated from the ball bore. The valve in closed position, system fluids
vent through vent passage to the vent port.
The valve in open position, no venting occurs, system fluids flow through the valve.
Choose either the Downstream Vent (DV) or Upstream Vent (UP) option.
