PVT-2000 AIRFLOW CONTROL VALVE

The PVT-2000 is a precision airflow control valve consisting of a Vortek VT-2000 airflow measuring device mounted in the inlet of a PRD airflow control valve.  A factory-installed current-to-pressure (I/P at 4-20 ma) or voltage-to-pressure (E/P at 2-10 vdc) transducer takes an electronic control signal from any airflow controller to modulate the PRD. The Vortek transmitter provides a
4-20 ma, 1-5 vdc or 2-10 vdc output to the airflow controller.  The use of these industry standard signals allow use with most airflow and temperature controllers presently on the market. A 24 vac or dc power source is required for the Vortek transmitter. Both the I/P and E/P are loop-powered, two-wire connection. Both the I/P and E/P require 20 psi clean, dry instrument air supply to operate.
Applications

  Room supply air and lab exhaust controls
  Cleanroom pressurization control
  Hospitals
  Industrial and process facilities

Advantages  Available with rectangular or circular inlet and outlet,
  Can be ordered in galvanized steel or stainless steel construction

  Well-suited to contaminated and corrosive airstreams

 

 

BLADE VALVE ELECTRONIC AIRFLOW CONTROL VALVE

The Tek-Air BVT2000 Series Airflow Control Valve uses the tried and true blade damper concept, and incorporates the dependable Vor-Tek Airflow sensor as an integral part of this assembly. The valve's postion is commanded by a separate controller's signal to the Belimo actuator.This Blade Valve assembly can be ordered in Fail Safe (FSC or FSO), or Fail in Last Place (FLP), and used with any controller that has 2-10 Vdc Analog inputs and outputs.
Applications

  Room supply air and lab exhaust controls
  Cleanroom pressurization control
  Hospitals
  Industrial and process facilities

Advantages  Available with rectangular or circular inlet and outlet,
  Can be ordered in galvanized steel or stainless steel construction

  Well-suited to contaminated and corrosive airstreams

 

 

ACCUVALVE ELECTRONIC AIRFLOW CONTROL VALVE

The AccuValve™ AV3000 airflow control valve is a revolutionary product in which Computational Fluid Dynamics (CFD) was utilized to aid in its design. This resulted in a valve that maximizes turndown while maintaining high accuracy throughout the flow range. The AV3000 is the first truly new design in airflow control valves in decades.

TFP-5000 DIFFERENTIAL PRESSURE AIRFLOW PROBES

The TFP-5000 Airflow Measurement Probes have an extremely low YAW angle effect throughout the 30° range, an improved signal-to-noise ratio, and they generate an amplified differential pressure signal, improving the ability to make low velocity measurements.  Insertion Probes can easily be installed in either new or existing ductwork by cutting small entry holes in either side and installing the sensors across the duct area.  Where the sensor must be removed for periodic inspection or cleaning, insertion probes provide an excellent measurement solution.  The TFP-5000 probes are manufactured in one-inch increments in lengths from four to 146 inches long, for rectangular, circular, and oval ductwork.  Achievable accuracies are typically within 2% of actual airflow. 

Applications

  Commercial and institutional applications
