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.
RAYS manufactures high-quality fully welded ball valves, forged from premium materials with side-mounted balls. The valves are available in two designs: cylindrical and spherical fully welded bodies. RAYS is particularly known for its cylindrical valve bodies.
The dual-plate wafer check valve features two semicircular, spring-loaded valve discs mounted on a central vertical pivot. When the valve opens, the force of the fluid and the spring act at the center of the disc, causing it to open from the base first. This design minimizes wear on the seal during opening, enhancing its durability. As the flow decreases, the discs slowly move back towards the seat due to the spring's force, ensuring a gradual closure. During backflow, the increased force on the discs leads to a faster closure, effectively reducing the risk of water hammer and hydraulic shocks. The spring’s force closes the top end of the disc first, preventing damage at the disc's base and prolonging the seal's lifespan.
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are also higher than those of cast steel parts.
