Handling Venturi Valves During the Installation Process
Valves should not be dropped or aggressively mishandled during installation.
Do not use the internal struts to carry or lift the valves. Lifting a valve by the strut could result in the valve going out of calibration.
Avoid standing the valve on its inlet side, as the cone assembly may extend beyond the opening when the valve is stroked to fully open.
Installing Venturi Valves
Prior to installation, make sure all packing materials have been removed from inside the valve body and that the valve is properly aligned with the ductwork.
Airflow through the valve must be such that the air enters the cone side of the valve. An airflow directional sticker with an arrow is placed on the side of all Triatek Venturi valves as reference to assist in proper valve orientation.
It is recommended that valves have 14 inches of clearance (around the controller and actuator) to allow for ease of installation and access to the electric wiring.
It is important that the outlet side of the valve requires approximately seven inches of unobstructed space in the duct to allow the shaft to reach the maximum flow position. If there is a reheat coil at the outlet of a Triatek supply valve, be sure to make space allowances for the valve stem movement.
Actuator and Linkage
While the actuator and linkage can face any direction, Triatek recommends that the actuator and linkage are positioned downward in case an adjustment is required.
However, in the unlikely event that condensation occurs, Triatek does not recommend that the actuator point directly down.
Installation of the valve with the actuator 20° from vertical will keep any condensation from running into the electrical wiring of the actuator, should there be any condensation buildup.
Triatek strongly recommends that valves are mounted in a horizontal position.
If a vertically-mounted valve is required, contact the factory so that the valve can be calibrated vertically, as this will minimize installation problems.
Vertical valves have a gravity-compensated calibration. The factory will also need to know whether the air entering the valve will be flowing downward or upward.
Triatek Venturi valves can be attached to the ductwork using a variety of methods, including use of a circular flange, draw-band clamps, and sheet metal screws (if the valve is not chemically-coated).
