Model:STV-PZ61-1500LB-DN50-A105N

Pressure self-tightening valve cover forged steel gate valve, the valve designed according to this connection form, the valve body and the valve cover are connected by screw mosquito, and the internal pressure is sealed from the sealing ring. The advantage is that the larger the internal pressure, the better the sealing performance.
1. Forged steel valve adopts pressure self-tightening seal, and the two ends of the valve body branch are welded.
2. The valve seat and disc sealing surface are made of cobalt-based hard alloy plasma spray welding, which has good wear resistance and scratch resistance.
3. The valve stem is treated by corrosion-resistant nitriding, which has good corrosion resistance and scratch resistance.
