It is not recommended to mount a valve directly to the pump as this could cause undesirable noise in
the system.
Sufficient clearance around the valve should be left for valve removal or repair.
Install valve in the direction of the flow arrows on the valve body.
The valve body has been designed to handle the weight of the pump on vertical in-line installations. The body
is not designed to support the piping weight. It is recommended that the piping be supported by hangers. Pipe
supports should be provided under the valve and strainer bodies.
Ensure that the Flo-Trex is installed with the valve stem in the upright position. Valve slam may occur if
installed in any other configuration.
3.0 - STORAGE
The Flo-Trex valve must be examined for signs of damage that may have occurred during transportation.
The Flo-Trex valve should be stored in a suitably sheltered environment to protect it from the effects of
weather, dust, dirt, and moisture.
The Flo-Trex valve is shipped with end caps on the inlet and outlet ends. These end caps should be left in
place until it is ready for installation.
The Flo-Trex valve should be stored at a constant temperature between -10°C to 40°C (14°F to 104°F).
4.0 - CLEANING
The Flo-Trex valve has been cleaned, inspected, and sealed at the factory prior to shipment. The protective
end caps will guard against entry of foreign matter and no additional cleaning should be required. A visual
examination of the interior of the body should be made to ensure that the Flo-Trex valve is free of contaminants.
5.0 - MAINTENANCE
The Flo-Trex valve requires inspection and periodic maintenance at regular intervals to maintain optimum valve
performance and prolong equipment life.
