Product Overview:
ATHENA pneumatic gate valve
- Pneumatic Actuator installed on the top of the bonnet which controls the open and close of the valve by pneumatic pressure.
- Metal Seal between the Body and Bonnet.Backseat seal between the stem and the bonnet, easy for the change of sealing stuff under pressure.
- Sealing surface is hard-faced or the QBQ with the performance of anti-corrosion, wear-resistance.
- Low operating Torque
- Working principle of pneumatic gate valve:
When using the air source to operate the gate valve, the small handle of the manual device must be turned to the pneumatic position to open and close the nut and the screw rod. When the compressed air enters from the upper pipeline of the cylinder, the piston and the piston rod in the cylinder are pushed straight When the compressed air enters from the lower pipe, the gas pushes the piston and piston rod in the cylinder to move upwards, and at the same time drives the valve stem to move upwards to open the valve. When there is no air source, the screw rod and the opening and closing nut can be used to open and close the valve.
