MAIN TECHNICAL PARAMETERS
Carbon steel material, pneumatic actuator control, proportional controltype (single-acting and double-acting available), voltage options: 24V,220V, valve pressure resistance: approx. 3000-5000 Pa, flange spacingL=200mm.

STRUCTURE
Main components: flange, valve body, valve disc, valve shaft, connectingrod and actuator. Round single-blade structure. Flange width can becustomized per customer requirements, standard width 30-50mm.

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