The instructions below detail general installation of a Venturi Valve without the use of any valve accessories. When using
accessories with the Venturi Valve, please see the appropriate installation detailed for the accessory being used in the
Valve
Accessories section.
Before Installation
General Installation Notes
1. Ductwork to be supported within eighteen inches (18”) of the Venturi
Valve unless otherwise specified.
2. Access doors are not required.
3. Leave eight inches (8”) of free space in all directions of the controls
enclosure to facilitate future access to the controls.
4. During operation, the center shaft of the Venturi Valve may extend past
the inlet or discharge of the valve. Ensure that a minimum of six inches
(6”) of duct is clear of any obstructions or obstacles (i.e. duct stiffeners)
from the valve inlet and discharge.
Enclosure Orientation
•
Visually inspect the valve for damage
o
Damage on the inlet of the valve can be detrimental to performance
o
Damage to the coating on fume hood valves can lead to corrosion
• Ensure the packing material has been removed from the inside of the
valve body.
• Inspect the tamper proof paint to ensure it has not been removed. Tamper
proof paint can be found on:
o
Mechanical linkage for constant volume and variable volume valves
o
Actuator for variable volume valves
o
Potentiometer for VAV Venturi Valves
•
Ensure the specification label for the valve matches the intended
installation location.
Supply (SAV) or General Exhaust (GEV) Applications
When installing a Venturi Valve in SAV or GEV applications, it is acceptable to install the
Venturi Valve with the control’s enclosure mounted in any orientation around the
circumference of the duct.
Fume Hood Applications
In fume hood applications, or in conditions that may cause condensation inside the
ductwork, the enclosure should not be mounted /- 30 degrees from straight down.
CAUTION
Do not screw into Phenolic or Kynar coated
valves. Screws will compromise the
Venturi Valve body and its resistance to
corrosion.
Warranty will be void if
screws are used.
