The ball valve is evolved from the cock, and its opening and closing parts act as a ball that rotates 90° around the axis of the valve stem for opening and closing purposes.
Controlling the liquid level of water tower or pool is simple to maintain, flexible and durable, high accuracy of liquid level control, water level is not disturbed by water pressure and closed tightly without leakage.
Ball screw gate valve is a large aperture high pressure gate valve, is the main part of the fracture tree.The SGA/D series ball screw gate valve is designed to meet API 6A and NACE MR-01-75 and is strictly quality controlled in accordance with ISO registration guidelines.The series of frac valves includes flanged ends, spiked outlets, and dedicated1
Product use: BQ41F heat preservation jacketed ball valve series is mainly used in petroleum, chemical, pharmaceutical, metallurgical, electric power and other systems to transport high viscosity medium which will solidify at room temperature. The jacket of the ball valve is welded between the sealing surfaces at both ends of the valve, and the stan1
Welded ball valves are widely use in various fields, Their superior quality and high performance stability are not achieved by ordinary cast steel ball valves, The service life of all welded ball valves is far greater than that of cast steel ball valves, All welded ball valves are widely uesd in city gas, urban heating, petrochemical, shipbuilding,1
