DN 50 - 1000 mm Motorized Flanged Globe Valve / Spherical Valve for high head hydro turbine

  DN50 - 1000 mm Motorized / Manual Drived Spherical Valve/Ball Valve

Specifications:

Spherical valves, as the name implies, are stop valves that use a spherical to stop or start the flow. The spherical performs the same function as the disk in the globe valve. When the valve handle is operated to open the valve, the spherical rotates to a point where the hole through the spherical is in line with the valve body inlet and outlet. When the valve is shut, which requires only a 90-degree rotation of the handwheel or Wormgear for most valves, the spherical is rotated so the hole is perpendicular to the flow openings of the valve body, and flow is stopped.

 They are widely used in fluid-handing systems for flow control. These types of Rotary Valves are suitable for corrosive applications. In general, Spherical valves offer many advantages when contrasted with other types of valves, they provide superior ease of operation, which can maintain and regulate high volume, high pressure and high temperature flow. Most spherical valves offer rugged construction providing with a long time service life, and a comparable low cost.

This type of Spherical valve operated by the electric motor, and also can by manual, It has a motor and wormgear box on the head of valve. The wormgear  are planetary gear operated. This type of gearing allows the use of a relatively small handwheel and operating force to operate a fairly large valve.
