ECON venturi type valve is pressure independent airflow terminal unit to control airflow accurately. Venturi type of valve is widely used in critical operation area to control fume cupboard face velocity and room pressure. The variable volume valve can maintain preset volume over a range of 150 to 750 Pa by internal spring cone structure to sense the pressure change across the valve.

ECON venturi valve is available in aluminum body with stainless steel components. When corrosion resistance required, special coating will be applied. ECON series have several standard sizes from 6 “ to 16” in diameter for single valve body. When more flow required than can be furnished through a single 16” valve, multiple valves can be paralleled to meet required additional flow. The venturi valve will control air flow for both supply and exhaust ducts based on air volume preset by fast actuator. This valve in its normal operating mode is pressure independent so that flow can always maintain constant volume.

Design Features 1.1

1.1 Design Features

ECON venturi valve incorporates a built – in sound attenuator. It is uniquely constructed of perforated aluminum with one-inch high quality fiberglass lined with special coating to resist erosion. The outside is covered with a 26 gauge galvanized steel jacket. The discharge and radiated noise levels are substantially reduced. The unit is completely thermally insulated.If required volume through valve is over single valve, multiple venturi valves can be paralleled to provide additional flow. The static pressure range is 150Pa to 750Pa. The material of valve body and cone are aluminum. The shaft is stainless and the bearing is Teflon or Heresite coated.

Special coating available if required.

ECON venturi valve can be controlled either by pneumatic or electric control system. No main air piping or consumption is required.

Standard Design Features:

· Fully pressure independent on range of 150 to 750 Pa· No main air consumption of pneumatic actuator· Factory set on range of whole designed volume· Fully insulated with 26g Galv. Cover· High accuracy of 5% on designed volume range· Less than 1 second response time· 16 points pre-calibrated in factory for VV valve· Compact design for easy installation

Optional Design Features:

· Hot water & electric booster coils· Dual duct systems· Multiple valve assemblies· Special coating provided for acid resistance· Pressure switch optional for fume cupboard alarm

1.5a Constant Volume (CV) Series

Pressure independent type

Constant Volume (CV)

Regardless of the change of static pressure across the valve, it accurately maintains preset volume through the valve according to the location of shaft which can be adjusted manually. The volume through is pre-calibrated in factory of the preset value. The cone structure moves by sensing the changing static pressure and if the pressure between valve ends increases, the cone will move towards the cylinder housing to increase the resistance and if the pressure decreases, the cone will move towards the opposite side to reduce the resistance and maintain the preset volume. Operator can adjust the lever to any position by reading the scale panel if the volume is required to change.

For highly accuracy required area, on site calibration is recommended.

1.5b Binary State (BV) / Variable Volume (VV) Series

Pressure independent type

Binary State (BV) / Variable Volume (VV)

Regardless of the change of static pressure across the valve, it accurately maintains preset volume through the valve according to the location of shaft which can be adjusted automatically by fast actuator either pneumatic or electronic. The BV type of venturi, only two position can be applied by analog signal or simple on-off signal. In factory only these 2 points are pre-calibrated.

Changing of the preset air volume is not suggested unless accurate on-site calibration can be ensured.

The variable volume type of venturi, 16 points will be factory pre-calibrated which will ensure accuracy for all the specified range.

The cone structure moves by sensing the changing static pressure when shaft position is fixed and if the pressure between both valve ends increases, the cone will move towards the cylinder housing to increase the resistance and if the pressure decreases, the cone will move towards the opposite side to reduce the resistance and maintain the preset volume.

Installation 1.7

1.7 Installation

Procedures for installing ECON series venturi valves:

1. Read all instructions before installing valves.

2. Check the tag number on valve label to ensure valve matches as scheduled.

3. Verify correct airflow direction and orientation of the valve as scheduled.

Valves mounted out of horizontal or vertical (as planned and factory calibrated) will affect performance and control accuracy.

4. Allow a minimum of 14 inches of free unobstructed around the valve for maintenance and installation. Generally the valve may be installed in a 360° rotation. However, single horizontal hood valves should be installed so that the pivot arm located between 8 and 4 o’clock (not within 4 to 8 o’clock).

5. Allow 6 inches of unobstructed space in the duct on valve’s inlet side for the shaft to reach the maximum flow position.

6. Use duct sealant on all valve/duct connection(or flange gaskets for circular flanges).

7. Install a hanger stock to support the ductwork within 12 inches of the valve connection. Install valve into duct after hanger stock is in position.

8. Follow appropriate installation diagram and abiding to relevant codes.

Screws, fasteners, duct sealant, hanger stocks, companion flanges, and gaskets are not provided with venturi valve.
