Box type pneumatic actuator
The box-type pneumatic actuator is composed of SC series straight stroke cylinder, manual mechanism and control accessories. The cylinder pushes the crank arm to drive the main shaft to rotate, converting the straight stroke of the cylinder into angular stroke output.
Box-type structure, all components are arranged inside the housing. Due to the protection of the box, it is suitable for working in harsh environments such as power stations, steel plants, petrochemicals, and desert areas. Mainly used to drive angular travel equipment such as damper baffles, fan blades, etc.

air lock valve
In the application of pneumatic actuators, if the air source fails, the actuator should immediately reach the safe position (hold position, fully open, fully close). This function can be achieved by installing and fixing the air lock valve on the air inlet and outlet of the pneumatic actuator. Air lock valves contain a pneumatic pressure switch that actuates 1 or more three-way control valves...

Pneumatic control box
Local control cabinet, bellows baffle control device. It is an important link necessary for the safe and economical combustion of the supporting boilers of thermal power plants.
The device accepts the DCS electrical signal, converts it into a gas signal and sends it to the on-site actuator to control the opening of the damper or the up and down swing angle of the swing burner. It is an intermediate signal conversion device between the control room and the field pneumatic actuator.
Suitable for boilers with burners arranged on the front and rear walls...
