MAIN TECHNICAL PARAMETERS
Carbon 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=300mm.

STRUCTURE
Main components: flange, valve body, valve disc, valve shaft, connecting rodand actuator. The flange width can be customized according to customerrequirements, with a standard width of 30-50mm.

PERFORMANCE
The valve is normally open or normally closed for ventilation under normalconditions. The valve disc is opened and closed by an electric actuator. Aproportional actuator can adjust the valve opening via 0-10V (4-20mA) inputsignal, and output open and close signals.
