KBKH Series Hydraulic Ball Valves
The KBKH Series hydraulic ball valves are a type of valve used in hydraulic systems to control the flow of fluid. These valves are designed to handle high-pressure applications and provide reliable performance in various industrial settings.The KBKH Series hydraulic ball valves feature a ball-shaped disc with a hole in the middle that controls the flow of fluid. When the valve is open, the ball allows the fluid to pass through the hole, and when it is closed, the ball blocks the flow, creating a tight seal. This design provides excellent shut-off capabilities and minimizes the risk of leakage.One of the key advantages of the KBKH Series ball valves is their ability to handle high-pressure applications. They are constructed using robust materials and engineering techniques to withstand the forces exerted by hydraulic systems operating at elevated pressures. This makes them suitable for use in industries such as oil and gas, manufacturing, construction, and agriculture.The KBKH Series hydraulic ball valves are available in various sizes and configurations to meet different application requirements. They can be operated manually using a lever or a handwheel, or they can be equipped with an actuator for automated control. The actuator allows for remote operation and integration with control systems, enhancing the efficiency and convenience of valve operation.These hydraulic ball valves also offer versatility in terms of flow direction. They can be designed for bi-directional flow, allowing fluid to pass through in either direction, or they can be designed for specific flow directions, such as one-way or three-way flow.

The KBKH series hydraulic ball valve is a quarter-turn ball valve that is designed for use in hydraulic systems. It has a robust construction and is available in a variety of sizes and materials to suit a wide range of applications.
The KBKH ball valve works by using a spherical ball with a hole bored through it to control the flow of fluid. The ball is held in place by two identical seat seals, one at each end of the valve body. When the valve is closed, the ball is rotated so that the hole is perpendicular to the flow path, blocking the flow of fluid. When the valve is open, the ball is rotated so that the hole is parallel to the flow path, allowing the fluid to flow through the valve.
The KBKH series hydraulic ball valve is actuated by a hydraulic cylinder. The cylinder is connected to the ball by a stem. When the cylinder is pressurized, the stem is pushed or pulled, rotating the ball and opening or closing the valve.
Here is a step-by-step explanation of how the KBKH series hydraulic ball valve works:
The KBKH series hydraulic ball valve is a versatile and reliable valve that can be used in a wide range of applications, including:
