Product Q&A

Q:What materials are used for the valve body and parts?

The body is made of ASTM A216 WCB or CF8. The wedge disc can be WCB, CF8, CF8M, or Monel. The stem options include F6A, F304, F316, or Monel.

Q:Can this valve be used for throttling or flow adjustment?

No, the cast steel gate valve is designed only for fully opening and closing. It cannot be used for adjusting or throttling the flow.

Q:What are the installation requirements for the valve?

The valve must be installed vertically with the stem in a vertical position. Ensure the cavity is clean, bolts are tightened evenly, and sufficient space is reserved for the drive mechanism.

Q:What is the testing procedure before installation?

For valves with working pressure greater than 1.0 Mpa, a strength test at 1.5 times nominal pressure and a tightness test at 1.1 times nominal pressure are required.

Q:How should the valve be maintained?

The valve should be lubricated at least once a month if used frequently. Avoid collision and extrusion to prevent damage to the seal.
