Price VV – Venturi Valve
Price Venturi Valves (VV) are mechanically pressure independent control valves designed specifically
for room pressure and fume hood control applications.
The highly engineered internal plunger assembly ensures the valve will respond to changes in duct
static pressure in less than one second, while turndown ratios in excess of 16:1 serve to maximize
energy savings in unoccupied or minimum flow set-points.
Each valve is factory calibrated, then characterized by flow to valve position using the latest N.I.S.T.
traceable equipment to ensure dependable and repeatable valve accuracy. Price Venturi Valves are accurate
to +/- 5% of flow when operated within the pressure range. Valve accuracy is unaffected by inlet conditions
and does not require any minimum distance of straight duct on the inlet or outlet of the unit.
Available in constant or variable air volume configurations, the Price Venturi Valve is able to
control flow without the need for measuring devices in the airstream, eliminating the possibility of
lint or other airborne particulates interfering with the control or accuracy of the valve.
Instead, electronic flow feedback is generated using a precision potentiometer in combination with
the Price Linear Module (LM) to output a VDC signal linearly proportional to airflow. The LM output
works seamlessly with Price controls and simplifies the task of field programming when integrating
Price Venturi Valves with 3rd party controls.
Price Venturi Valves are available with integrated silencers and/or HW or electric reheat coils
as AHRI certified assemblies. All silencers and reheat coils are manufactured in-house with designs
optimized for close-coupling with the Price Venturi Valve.
