MARS Z-Plate Strainers - Sand Trap

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.


Sand and 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.
