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 C700 Series Low-Noise Control Valve is divided into the CN702 and CDN702 series, mainly designed to reduce the noise of compressible fluids. To adapt to the throttling, diffusion and expansion of gases, the valve core adopts a pressure-balanced structure, and the sleeve is equipped with many symmetrical small holes to reduce pressure drop. The fluid passage is in an S-shaped streamline, and a deflector wing is also provided to improve the smooth flow of the fluid around the sleeve. Therefore, the control valve has low pressure drop loss, large flow rate, low noise and less cavitation corrosion. The control valve is equipped with the RSMF series multi-spring pneumatic diaphragm actuator, which has a simple and compact structure, stronger stability, large output force and long service life.
The high-temperature ball valve is a special type of valve designed for high-temperature and high-pressure environments. It can effectively control the on-off of high-temperature and high-pressure fluids. It can operate stably under harsh conditions and meet the precise control requirements in industrial production processes. It is widely used in the petroleum, chemical, natural gas, and power industries.
When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
