Butterfly Valve

  • Butterfly ValveButterfly valve is a kind of regulating valve with simple structure. It can be used for controlling medium in low pressure pipelines. The opening and closing switch of this water valve is a butterfly plate. The plate rotates around its own axis so as to achieve the purpose of flexible opening and closing or regulation. Butterfly valve can be applied to different mediums and temperatures. Besides...
  • The metal hard sealing butterfly valve adopts three-eccentric valve seal structure, which ensures the reliability of the butterfly valve. The valve seat and disc has almost no wear and has the tight seal function. Sealing ring chooses stainless steel with metal hard seal and elastic seal advantages. Whether in low temperature or high temperature circumstances, this hard seal butterfly valve ...
  • Turbine Inlet Butterfly ValveThe turbine inlet butterfly valve in a hydro power station is used as a safety device. The valve is located within the power house on the upstream side. It is basically a turbine inlet valve having less head loss. The hydraulic power pack is mounted on the driving end of the valves. For small and medium turbines where grid power is not available, the turbine inlet butterfly valve is opened by a hand pump ...
  • Hydraulic Control Butterfly Valve for Pumping Station-1Hydraulic control butterfly valve for pumping station is a kind of hydraulic butterfly valve. It is applied to pump outlet and turbine inlet piping. As a closed-circuit valve and check valve, it can avoid and reduce medium backflow in the piping system so as to protect the piping system. The hydraulic control butterfly valve for pumping station is widely used in large and middle pipelines, pumping stations...
  • Hydraulic Control Butterfly Valve for Pumping Station-2Hydraulic control butterfly valve for pumping station has become a substitution of gate valve and check valve. It is equipped at the pump outlet which performs the functions of cutting off and no return. Nominal diameter of this water valve varies from 1000 to 3000 mm. Nominal pressure ranges from 0.25 to 1.0MPa. Hydraulic control butterfly valve is widely used in large and middle pipelines ...

Butterfly valve is also called flap valve. It is a kind of regulating valve used for isolating or regulating flow. The "butterfly" is a metal disc mounted on a rod. The disc is positioned in the center of the pipe. There is a rod connected to an actuator on the outside of the butterfly valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. When this flap valve is closed, the disc is turned so that it completely blocks off the passageway. When this water valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. CORROCO can provide metal hard sealing butterfly valve and hydraulic control valve for pumping station. They are greatly favored because they are lower in cost and lighter in weight to other valves.

Butterfly valve is suitable for all kinds of corrosive, non corrosive fluid pipes in environmental protection engineering system, such as coal gas, natural gas, liquefied petroleum gas (LPG), city gas, heat and cold air, chemical smelting and power generation, etc. This flap valve can regulate and truncation medium flow.

1. Butterfly valve has the features of simple structure, small volume, small installation size, reciprocating rotary, small driving moment, etc. It is used for intercepting and adjusting the medium in pipes. It also owns good fluid flow controlling function and seal performance.
2. This flap valve can transport mud. It has low pressure and good regulation performance that can achieve good sealing.
3. The butterfly plate is geometrically designed, which makes fluid resistance lose less. Our butterfly valve is a kind of energy-saving products.
4. After quenching and tempering, this flap valve rod has good mechanical properties and corrosion resistance.
