Purpose and specification:
Npz series wear-resistant slag discharge gate valve is a new product recently developed by our factory. The product has the characteristics of reasonable structure, flexible opening and long service life. It is mainly suitable for iron ore, molybdenum ore, water ash removal and other conveying slurry and slag water mixing systems with nominal pressure less than 6.4Mpa and working temperature ≤ 200 ℃. It is used as a new wear-resistant slag discharge valve for idling.
