China RF Free Maintenance Food Grade Manual Butterfly Type Ball Valve

RF Free Maintenance Food Grade Manual Butterfly Type Ball Valve

Application:
RF Free Maintenance Food Grade Manual Butterfly Type Ball Valve is a kind of automatically or manually manipulation of butterfly type ball valve,because of it can be very good deal with viscous or medium with particulate,which is widely used in food,beverage,pharmaceutical and chemical industrial piping system,to regulate and control the medium flow in the system.
Operating Principle:
Butterfly valves are a type of quarter-turn valve used to regulate the flow of a fluid. The valve mechanism requires a 90-degree turn to go from the fully open to the fully closed position. The basic butterfly valve has three primary components: A disc, a stem, and a seat.
The disc is a thin, typically circular, metal plate that opens or closes the valve. When the valve is opened, the disc is aligned parallel to the fluid flow, allowing unrestricted flow. When the valve is shut, the disc is perpendicular to the fluid movement, using its surface area to prevent flow through the pipe.
The stem is a shaft that transmits motion from the handle or actuator to the disc. In some applications, the stem may be combined with the handle or disc as a single component.
The valve seat seals the gap between the pipe flange and the valve disc to provide shut-off. The performance of butterfly valves is heavily dependent on the quality of the seat construction and its ability to seal.
Design Features:
Free maintenance
Portable and compact
