Large-caliber gate valves are made of the best quality ductile iron or carbon steel. They have the characteristics of high strength, light weight and precise geometric size. The gate boards have the function of interchange, and the spiral bevel gear labor-saving mechanism is installed. One person can switch easily and freely, and also can install the opening and closing indicator column according to the requirements of users, or electric, pneumatic systems, municipal construction and mines.
1. Flat-bottomed seat, no accumulation of dirt, make the seal more reliable.
