1. The middle cavity of the valve adopts a pressure self-tightening sealing structure, which has good sealing performance.
2. The valve disc and valve seat seal are made of stellete cobalt-based hard alloy surfacing. The valve stem is quenched, tempered and nitrided, which is wear-resistant and high-temperature resistant, and its anti-friction performance has been greatly improved.
3. The valve is used to cut off or connect the pipeline medium of various systems such as petroleum, chemical industry, hydraulic power, thermal power station, etc. with nominal pressure PN20.0~32.0MPa and working temperature of P54100V-P57170V ≤540℃. The applicable medium is water, oil, steam, etc. Operation modes are: manual, gear transmission, electric and so on.
