Stainless steel electric air valve

Comprehensive analysis of stainless steel electric air valve
1、 Definition and Structure
Stainless steel electric damper is a device that controls the direction and flow of airflow in a ventilation system through electric drive. It consists of three main parts: valve body, actuator, and control system.
Valve body: Made of 300 series stainless steel material, it has corrosion resistance and high temperature resistance characteristics. The structure is mostly designed by welding the center line disc plate and short steel plate, which combines lightweight and high pressure bearing capacity.
Execution mechanism: includes an electric motor and a driving device, which can accurately adjust the opening and closing angle of the valve disc by 67 degrees.
Sealing material: The contact surface between the valve plate and the valve body is sealed with high elasticity sealing strips to ensure zero leakage in the closed state.
2、 Working principle
When the control system (such as sensors or remote commands) sends a signal, the electric actuator drives the disc plate to rotate within the range of 0-90 °, and adjusts the gas flow rate in the pipeline by changing the opening and closing angle. Supports manual and automatic control modes, and can be linked with intelligent building systems to achieve dynamic air volume management.
3、 Core advantages
Corrosion resistance: Stainless steel material is suitable for humid, dusty, and corrosive environments, extending equipment life by 37.
High stability: The electric actuator responds sensitively, supports long-term continuous operation, and is not easily stuck.
Convenient maintenance: Modular design simplifies the installation process, and daily maintenance only requires cleaning and lubrication.
Strong economy: Some models have unit prices as low as tens of yuan, balancing functionality and cost control.
4、 Application scenarios
Industrial field: Air volume regulation and high-temperature smoke exhaust in metallurgical, power, chemical and other scenarios.
Civil buildings: air conditioning and ventilation systems for commercial buildings, subway stations, and local ventilation control for kitchens and bathrooms.
Special environment: Laboratories and clean workshops that require explosion-proof or anti-corrosion measures.
