Custom Cut Off ball Valve Manufacturers

The BR.W8 series ball valve has excellent cutting performance. When fully open, its flow path and pipeline inner diameter are basically the same, and the fluid pressure loss is minimal. Therefore, it is suitable for cutting and control of various liquids, gases, slurry and other fluids. Ball valves can be divided into O-ball, V-ball, three-way ball valves, and eccentric rotary valves to meet different working conditions and on-site requirements. The O ball has a simple structure, small volume, smooth flow channel, low flow resistance, and high flow capacity, without any flow direction requirements for the medium. The V ball can add adjustment functions on the O ball and is more suitable for medium with high viscosity. Three way ball valves and eccentric rotary valves can play their unique roles under specific working conditions, such as the diversion and confluence of three way ball valves, and the cutoff and adjustment function of eccentric rotary valves on particulate media. The conventional materials for ball valves are carbon steel and stainless steel, and special alloy materials such as Ti, Hastelloy C, duplex steel, etc. can also be selected according to on-site conditions. Metal lining F46 or PFA can also be added to cope with corrosive media. The maximum nominal pressure of this series can reach 2500Lb, and the maximum diameter can reach DN500.

News and Information

Industry Knowledge

What are the key design differences between O-ball, V-ball, and Three-way ball valves?

The key design differences between O-ball, V-ball, and Three-way ball valves lie in the shape of their ball or disc and the number of flow paths they provide. These differences have a significant impact on their applications in industrial processes:
1. O-Ball Valve:
Design: O-ball valves have a spherical or rounded ball with a circular bore through the center. The bore creates a circular opening when fully open.
Applications: O-ball valves are commonly used in applications that require on/off control. They provide excellent sealing when fully closed, making them suitable for isolating fluid flow.
2. V-Ball Valve:
Design: V-ball valves feature a ball with a V-shaped or conical bore. The V-shape allows for precise control of flow rates by adjusting the position of the ball.
Applications: V-ball valves are often used in applications that require modulating control, such as regulating flow rates. They excel at maintaining flow stability and offer superior control over the flow profile.
3. Three-way Ball Valve:
Design: Three-way ball valves have a ball with a T or L-shaped bore that provides multiple flow paths. By rotating the ball, the valve can divert or mix flows between different ports.
Applications: Three-way ball valves are versatile and find use in applications where fluid direction needs to be changed or mixed. They are often used for blending, diverting, or isolating fluids in complex piping systems.

What actuation options (manual, pneumatic, electric, etc.) are available for Cut Off O-ball, V-ball, and Three-way ball valves?

Cut Off O-ball, V-ball, and Three-way ball valves can be actuated using various methods to suit different process control needs and automation requirements. Here are some common actuation options available for these valves:
1. Manual Actuation:
Handwheel: Manual handwheels are the simplest form of actuation. They allow operators to manually open or close the valve by turning the handwheel.
Lever: Lever-operated valves offer a quick and easy means of manual actuation. They are often used in applications where frequent manual control is required.
2. Pneumatic Actuation:
Pneumatic Actuator: Pneumatic actuators use compressed air to operate the valve. They are commonly used in industries where rapid actuation and remote control are needed.
Spring-Return Actuator: Spring-return pneumatic actuators use compressed air to open or close the valve and rely on a spring to return the valve to its default position when air pressure is released.
Double-Acting Actuator: Double-acting pneumatic actuators use compressed air to open and close the valve, providing precise control of valve position.
