SPECIFICATION

1.Manufactured and Tested in Accordance with API Spec 6A

2.Simple structure and renewable gate and seat assembly.

3.One-piece and double-acting gate with long service life.

4.Both thrust bearings with large load capacity and composite rubber-plastic stem lip packing minimize operational torque.

5.Bearing cap is provided with a grease cup to make it easy to inject lubricating grease in the field.

6.Threaded packing gland allows removal of bearings and stem packing under Line pressure.

7.Both the bolted bonnet and modern bonnet seal ring provide simple structure And reliable sealing.

8.The sealing surfaces of the gate and seat are hardfaced for wear and corrosion resistance.

9.Wave springs are installed between the body and seat and between the gate and seat.The gate and seat still maintain a positive metal to metal seal under low pressure.

10.Floating gate design requests the hand wheel to be backed off 1/4 turn after its

rotation can go no further.

 

 

NOTES

Under pressure, the valve is forbidden to be semi-shrouded, for it will do great harm to the gate valve and great reduce the service life of the valve.
