ZECO ball valves can be divided into cast steel and forged material ball valves. Ball valve products are widely used in petroleum refining, long pipeline, chemical industry, LNG, LPG, etc. 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.
Driven by the stem, the ball valve revolves around its axis. According to the structural form, ball valve can be divided into Floating ball valves, trunnion mounted ball valve, top entry ball valve, metal seated ball valve, full weld ball valve and industrial ball valve.
The drive mode of the ball valve can be divided into manual, pneumatic and electric, gear operated and motorized. The quality of the ball valve is not only related to the quality of the product itself, but also relevant to select the type correctly.
When buying ball valve, it is significant to compare the different materials that are used to manufacture ball valves. The selection of the material used in the ball valve depends largely on the service condition of the valve. Body materials of ZECO ball valves include, but are not limited to stainless steel, wcb, carbon steel, forged and cryogenic.
The size of the pipe determines the size of the ball valve and the rate of flow required through the ball valve is considered first. ZECO international standard valve company manufactures the ball valve of smallest 1/2 inch, 3 inches, 4 inches, 6 inches, 8 inches, 12 inch, and maximum 56 inches.
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 venture type in those of a reduced bore.
ZECO has nearly 30 years of experience in the field of ball valve in research and development, manufacture, production of the metal seated ball valve. Sealing surface hardness and ball surface hardness, as well as the degree of the match after grinding, can achieve world-class standards. ZECO ball valves feature a 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. From refrigerants to highly corrosive fluids, ZECO products are manufactured and tested according to the corresponding API, ASME and ANSI standards.
