manual handle lever or gearbox UPVC butterfly valve FPM VITON lined
Short Description:
Butterfly valves are a common valve type used in large diameter pipes. They are typically used for basic on/off service, but can also be effectively used to throttle flow. They are operated with a simple 90 degree turn (quarter-turn) of a disc shaped obstructor. This disc has a slim profile around which flow passes when parallel to flow, but stops the flow in the when rotated 90 degrees to fill the entire opening of the valve. handle lever type plastic wafe...
Butterfly valves are a common valve type used in large diameter pipes.
They are typically used for basic on/off service, but can also be effectively used to throttle flow.
They are operated with a simple 90 degree turn (quarter-turn) of a disc shaped obstructor.
This disc has a slim profile around which flow passes when parallel to flow, but stops the flow in the when rotated 90 degrees to fill the entire opening of the valve.
handle lever type plastic wafer butterfly valves have 9 positioning scale tooth, easy to position the angle of the disc and easy to control the water-flow; Blue round cap be free for your own logo; Reinforced keel disc is strong enough for any water pressure; Remove the handle & positioning plate, Gearbox or Pneumatic or Motorized actuator is available。

wafer butterfly valves can both isolate and regulate flow in a system. These valves work in similar fashion to a ball valve, allowing for a fast shutoff when necessary. They are a bit more affordable than ball valves of similar sizes, and also weigh less, so they do not require as much support as ball valves. wafer butterfly valves can be used in a variety of applications where precise flow pressure is not required, such as irrigation, food processing, chemical processing, manufacturing and home plumbing systems.
NOTE: Most butterfly valve installs require flanges and a stud kit for installation.
