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.
Expanding Slab Gate Valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
The axial-flow check valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
