How do I maintain a resilient seat gate valve?

To properly maintain a resilient seat gate valve, follow these steps:

1 Regular Inspection:

Check for any visible signs of wear, corrosion, or damage.Inspect the valve body, stem, and sealing surfaces.

Ensure that the valve operates smoothly without any sticking.

​

2 Lubrication:Apply a suitable valve lubricant to the stem threads and the gate wedge.Lubricate the stem nut and other moving parts as needed.

Follow the manufacturer’s recommendations for lubrication frequency.

​

3 Operate the Valve:Regularly open and close the valve to prevent it from becoming stuck.

Avoid excessive force during operation.If the valve has been unused for an extended period, exercise it to maintain flexibility.

​

4 Sealing Surface Cleaning:Remove any debris or buildup from the sealing surfaces.Use a soft brush or cloth to clean the gate and seat.Avoid abrasive materials that could damage the elastomer coating.

​

5Replace Damaged Parts:If you notice significant wear, cracks, or other damage, replace the affected parts promptly.Common replacement parts include the gate, stem, and seat.
