Explosion-proof electric valve consists of valve body, actuator and explosion-proof control box, commonly used in ventilation unit exhaust duct mouth, the precise adjustment of air flow is to achieve a variety of environments, one of the key control ventilation mode, the The main features are flexible operation, low noise, small leakage, (confined leakage <0.5%) wide operating temperature range, reliable structure, safe and convenient.

The wind valve according to the shape of sub-circular valve and rectangular damper; according to the control valve opening signal is different, and can be pided into analog proportional valve and the switch to adjust the damper;

The body is welded galvanized steel, insulation valve body and valve explosion-proof galvanized steel double foam insulation between the middle measures, thermal insulation performance is good;

The actuator uses high-quality drive motor, with double limit, overheat protection, overload protection, reliable operation, low failure rate;

The actuator drive power can be customized for AC220V or DC24V; corner of 0-90 degrees;

The proportioning valve input signal can be selected by DIP switch: pided into 4-20mA current signal, 0-10V voltage signal or 2-10V voltage signal;
