General Information
Liquid Controls valves are designed for a wide range of
applications and flow rates and have minimum head loss.
Careful engineering and construction ensure smooth,
accurate, and controlled operation.
The V-Series mechanically actuated piston valves are
available in 3” and 4” sizes, and are designed for
mounting on the meter outlet to provide tight shut-off with
smooth and easy operation regardless of system line
pressure. The valves may be manually operated or
connected via a mechanical linkage to a preset counter
on the meter for singe-stage closure (for low flow
applications) or two-stage closure with dwell period to
eliminate hydraulic shock. The valves are indexible in
90º increments for up, down, or side facing outlet.
