 Power Station Gate Valve

Power station gate valve provided in KIST is available in 2 types: ANSI B16.34, JIS E101 and GB standard. It is generally accepted in the water pipeline, steam pipeline, and oil pipeline of thermal power plant, oil plant, chemical plant and other high-temperature high-pressure applications.

Considering the high-temperature and high-pressure environment of power station pipeline, this kind of gate valve is designed with self-tightening structure. Its seal ring is available in 2 materials: low-carbon steel and flexible graphite 316. The sealing layer is welded with cobalt-based hard alloy, the pure metal layer of which is thicker than 3mm, endowing the valve with great performance of abrasion resistance, high temperature resistance, and corrosion resistance. The 2 ends of the valve are welded according to the bevel standards or clients' requirements.

In addition to standard valve products, KIST also offers customization service according to clients' actual needs.
