Z-Plate Strainers are designed to protect water meters from
the effects of foreign matter and debris. The Z-Plate design is beneficial to
the hydraulics of a water line by canceling the turbulence and providing
smooth, laminar flow, thereby reducing the need for the installation of 8 to 10 diameters of straight pipe ahead of the in-line meter. The unique Sand Trap design enables flushing of the strainer by using a
valve key to open the ball valve for a brief instant
which uses normal line pressure to flush entrapped
sand and debris.
The Z-Plate Strainers can be easily serviced without removal
from the main line and should be installed upstream from the in-line meter.
debris do not enter the state of suspension until the velocity in
the pipeline exceeds 8 feet per second or other obstructions
cause a stirring action. Sampling of the sand and debris is
made possible by attaching a pipe directly to the ball valve to
vent into a container. This allows for evaluation and analysis
of pipeline deterioration.
The placement of the Z-Plate Strainer ahead of the in-line meter
will maximize revenue and extend the life of the measuring element. To be
used only in POTABLE COLD WATER up to 120° F (50° C) and Working Pressure
up to 150 PSI. Working Pressure tests are performed prior to shipment.
No further adjustments are required before installation.
The Z-Plate Strainers comply with all material and
design requirements of the American Water Works Association Standards
C701 and C702, as most recently revised.
