Venturi principle

Uses a cone and spring mechanism to precisely control airflow with high stability.

Corrosion-resistant features

Aluminum alloy or stainless steel housings can be fitted with phenolic or Teflon coatings for excellent corrosion resistance.

Wide turndown range

Airflow turndown ratio up to 1:20 for varying operating conditions.

Maintenance-free design

Mechanical structure with maintenance-free design for long-term stability and reliability.

Fast response

Steady-state response time complies with ASHRAE 110 and DIN EN 14175-6, preventing hazardous gas escape.

Before Installation

• Confirm that valve selection matches environmental control requirements
• Confirm valve orientation and airflow direction, and reserve maintenance space
• Confirm power supply and component wiring

Installation Steps

• Install in the duct according to valve orientation and airflow direction
• Seal duct connections at both ends
• Connect internal component wiring if applicable
• Connect power and signal cables if applicable
• Power-on test if required

Commissioning Points

• Confirm that valve operating differential pressure meets requirements
• Set parameters such as face velocity and pressure differential
• Test system control performance

Clean Ventilation Systems

Airflow and pressure control for cleanroom supply and exhaust systems.

Laboratory Ventilation System

Fume hood face velocity and room airflow balance control for laboratory ventilation systems.

Hospital Buildings

precise airflow control for operating rooms, wards, and other hospital areas.

Nuclear Industry

For nuclear power plants, nuclear fuel components, and radiopharmaceutical platforms, ensuring airflow balance and environmental control targets.
