MAIN TECHNICAL PARAMETERS
Stainless steel material, controlled by electric actuator (on-off type andproportional control type available). Voltage options: 24V, 220V, 380V. Valvepressure resistance: approx. 3000-5000 Pa. Flange spacing L=200mm.

STRUCTURE
Main components: flange, valve body, valve disc, valve shaft, connectingrod, silicone sealing sheet and actuator. The flange width and thicknesscan be customized according to customer requirements, with a standardwidth of 30-50mm.

PERFORMANCE
The valve is normally open or normally closed during ventilation operation.The valve disc is opened and closed by an electric actuator, and a propor-tional actuator can adjust the valve opening via an input 0-10V (4-20mA)signal and output open/close signals.
