Brief introduction:

reduced bore casting trunnion mounting ball valve is comparatively lighter in weight,but its fluid resistance is only 1/7 of that of globe valve of the same caliber. So, reduced bore ball valves boast of broader prospects. 

Trunnion ball valves are mainly used in the industries of natural gas, oil products,chemicals, metallurgy, urban construction, environmental protection, pharmaceuticals, foodstuff and etc. Among them, the sulfur-resisting series products are applicable for seriously corrosive natural gas pipeline containing hydrogen sulphide mediums and impurities.
