Water-Cooled Hot-Blast Valve

Qinhuangdao Zhongqing Metallurgical Valve Co., Ltd.

Product overview

Welded metallurgical isolation valve for a hot-blast stove system.

Zhongqing’s hot-blast valve uses a welded body and water-cooled body and closure components. The catalog describes hydraulic or electric operation and requires pressure equalization for opening and closing. Its schedules separate DN500–1300 and DN1300–2200 pressure groups; the water-cooling circuit and the selected size group are therefore essential parts of a project enquiry.
