Brief：
Din Standard Globe Valve
1. Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal.
2. Ergonomic hand wheel. It provide longer service life and easier operation.
3. Heat-treatment and nitrogen treatment. After these measures, the stem will have the function of corrosion-resistance and friction-resistance. http://www.vmv-valve.com/ | 。 |
