thermal power stations,as regulating and intercepting devices use,it is also widely applied in the pipelines of steam,gas, SO2,air,ammonia,water,saline water,lye seawater,nitric acid,hydrochloric acid ,sulfuric acid,phosphoric acid and other media in smelting,medicine,food and other industries.
TOP FLANGE:ISO5211
All valves are pressure tested to 110% of rated pressure to assure bubble tight shutoff.
NOMINAL DIAMETER:DN40-DN1400
