Details

The closing member of the national standard stainless steel globe valve is a cylindrical disc with either a flat or conical sealing surface, which moves linearly along the fluid’s central axis. National Standard Gate valve It is only suitable for fully open and fully closed positions and is generally not used for flow regulation. However, custom orders may allow it to be used for both adjustment and throttling.

[Product Features]

1. Simple structure, making manufacturing and maintenance relatively convenient.

2. Short working stroke and quick opening/closing time

3. Excellent sealing performance, with low friction between sealing surfaces and a long service life.
