Three-way ball valves can be L-shaped or T-shaped. L-shaped three-way ball valves have one inlet and one outlet, and the third port is used as a
bypass; T-shaped three-way ball valves have two inlets and one outlet, or one inlet and two outlets. Three-way ball valves are often used in piping
systems that require flow direction changes or bypass operations, such as in chemical, oil, natural gas, and water supply systems. Multi-way ball
valves can control the flow direction of fluids in multiple pipelines, allowing multiple operations on one valve, such as distributing, mixing, or isolating fluids. Multi-way ball valves are suitable for complex piping systems that require precise control of fluid distribution, such as petroleum refining,
chemical processing, multi-product pipeline transportation, etc.
◎ Design Standard: API6D, ASME B16.34, GB/T 19672, etc.
◎ Material: Carbon steel, Stainless steel, Alloy steel.
◎ Nominal Size: 2"~24"DN50~600
◎ Nominal Pressure: CLASS150LB~2500LB PN10~PN420
◎ Applicable Temperature: -60℃~250℃
◎ Operation Mode: manual, worm, pneumatic, electric, etc.
◎ Scope of Application: Widely used in production equipment in the petroleum, chemical, pharmaceutical and other industries. In these industries, three-way and multi-way ball valves can be used for opening and closing of various pipelines or flow control in the regulating system. For example, in the petrochemical production process, three-way and multi-way ball valves can control the mixing ratio of different oil products to meet production needs. In the pharmaceutical industry, three-way and multi-way ball valves are used to accurately control the flow direction and flow of liquid medicine to ensure the quality and safety of medicines. In the textile, food and other industries, three-way and multi-way ball valves also play an important role in controlling medium flow, distributing fluids, adding materials, etc.
The cryogenic butterfly body can be provided in two structural forms, namely flange connection and butt. welding connection (both with inspection ports). The body with inspection ports can replace the valve internals online, making maintenance work extremely simple, which is conducive to the rational use of resources and saving maintenance costs. The extended valve cover + drip tray design ensures that the temperature at the stuffing box is above zero degrees, so that the connection between the stuffing and the stem will not freeze and lock. Through the use of three-dimensional simulation optimization design, effective control of material changes under cryogenic conditions, selection of high-quality materials and effective processing technology to meet the stable performance of materials under cryogenic conditions. This series of valves has good sealing performance, high reliability, light weight, compact structure, and no need toworry about abnormal increase in valve cavity pressure. lt isan ideal valve for conveying cryogenic media and can bewidely used in cryogenic conditions in liquefied natural gas,aerospace and other fields.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
Designed specifically for deep cold medium working conditions such as LNG, liquid nitrogen, and liquid oxygen, it adopts special stainless steel or low-temperature alloy valve bodies. Through deep cold treatment, it ensures reliable sealing even in an extreme environment of -196℃. The innovative lateral maintenance port structure allows for quick replacement of the sealing components without disassembling the valve, significantly improving maintenance efficiency. The optimized double eccentric butterfly plate, combined with multi-level metal hard seals, achieves zero leakage and long service life under ultra-low temperature conditions. At the same time, it is equipped with a longened valve stem heat insulation structure, effectively blocking the conduction of cold energy.
