Hollow jet valve

Hollow Jet valves are mainly used as discharge valve in turbine bypass valves , reservoir or other discharge purpose and can regulate flow also.These valves are used to discharge water at high pressure from reservoirs or full pipes into atmosphere. Some designed valves can also work submerged in the water. A hood can be incorporated at the end of the valve.

The hollow jet valve is a type of valve used in fluid control systems. This valve is designed with a hollow or cavity in its center, allowing a fluid to pass through it. It is commonly used in applications where high velocity and direction control of the fluid are important. The hollow jet valve typically consists of a body with an inlet and outlet, and a movable orifice or disc that controls the flow of the fluid. When the valve is in the closed position, the orifice blocks the fluid flow. As the valve is opened by moving the orifice away from the seat, the fluid can pass through the hollow center and exit through the outlet. Hollow jet valves are often used in water dam, and power generation. They are particularly useful in controlling high-pressure or high-velocity fluid flows, where precise control and efficient operation are necessary. The design and materials used in hollow jet valves can vary depending on the specific application and the type of fluid being controlled. Factors such as pressure, temperature, and chemical compatibility need to be considered when selecting a hollow jet valve for a particular system. Regular maintenance and inspection are important to ensure the proper functioning of these valves and prevent any leakage or failure.

Our hollow-jet valves have proved their high efficiency in hydroelectric power plants and irrigation dams. They ensure a regulated and environmentally compatible outlet of water either to the outside or into underwater tanks. The water is also enriched with oxygen at the same time. The high-quality steel construction of the hollow-jet valves combined with elastic/metallic sealing enables energy dissipation without cavitation.
