GT series (open type flat gate valve)

The expansion type flat gate valve is designed according to the API 6D standard. Due to its unique dual gate structure for expansion sealing, it can achieve excellent bidirectional sealing performance under both high and low pressures. The greater the torque, the tighter the seal. During the switching process, the sealing surface of the gate and the sealing surface of the seat ring detach, reducing the wear of the sealing surface and extending the service life of the valve. Given these characteristics, this valve is widely used in high-temperature and high-pressure pipelines.
