Product Description

Advantages of COVNA Pneumatic Control Valves:

●High cost performance, safe to use, can help you save the maintenance cost of COVNA single seat pneumatic globe valve of the whole system.
● Simple structure, large torque, explosion-proof, short action time, optimized action force, and reliable sealing.
● Perfectly avoid friction, corrosion, emission and other problems.
● Low center of gravity, strong vibration resistance and easy installation.
● Simple control, quick response, intrinsic safety, no need to take additional explosion-proof measures.
● The flow channel is S-shaped streamline, the pressure drop loss is small, the flow rate is large, the adjustment range is wide, and the flow rate accuracy is high.

●COVNA pneumatic control valve has good adjustment stability. For the working conditions with large pressure difference, the cavity of the valve body is enlarged to improve the buffer capacity of the valve body
