HOKE Factory was established in 1925, which is the oldest famous instrument valve and pipe fitting factory in the United States. Its patent Gyrolok.
The safety, operability, durability and reliability of the double jacketed joint are unique whether it is under pressure, temperature resistance or working conditions requiring leak-free sealing. At the same time, its patented Dyna-Pak sealing system makes its ball valves, needle valves and other valves show excellent quality in pressure bearing, temperature resistance and sealing performance. With a long history, leading industrial standard design and high quality, HOKE products are widely used in oil/gas, oil refining, petrochemical, fine chemicals, paper making and various processing and manufacturing industries, and enjoy a high reputation.
