With the rapid development of research and development technology and material technology, ball valve has gradually become the main valve and gradually replaced the plug valve, and the operating temperature range has been the same as other types of valves, and compared with other types of valves have obvious advantages, its advantages reflected in the switch is simple and low torque, and minimum pressure drop-almost the same as the equivalent to the length of the pipe in the full bore valves-and equivalent to a reduction ventury type in those of a reduced bore. 

ZECO is a valve factory. ZECO Valve is a professional production of floating ball valve, trunnion mounted ball valve and top entry ball valve manufacturer, and in the field of ball valve has nearly 30 years of experience in research and development, manufacture, production of metal seated ball valve sealing surface hardness and ball surface hardness as well as the degree of match after grinding can achieve world-class standards, ball valve products are widely used in petroleum refining, long pipeline, chemical industry, LNG, LPG, etc. From refrigerants to highly corrosive fluids, ZECO ball valves feature long life and safe operation in harsh environments. Maximum safety and environmental protection is the driving factor for each design. The ZECO valve is achieved through corrosion resistant materials, fire safety testing, blowout preventer stem and tight shutoff. 

ZECO is a famous ball valve manufacturers.

ZECO ball valves can also be divided into cast steel and forged material ball valves. ZECO products are manufactured and tested according to the corresponding API, ASME and ANSI standards. ZECO ball valve features dual block and bleed capability, secondary sealant injection and spring-loaded self-releasing seats, providing many beneficial features and options for oil, gas and liquid applications.
