Product Description

Application:
RF Hygiene SS 304 /316L Stainless Steel Welded Butterfly Type Ball Valve used in food, beverage, wine   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: 
RF Hygiene SS 304 /316L Stainless Steel Welded Butterfly Type Ball Valveused in food, beverage, wine  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
Small torquemoment
Valve body can be replaced in any connections,and the length will not change.
Handle can be installed on the side of the valve body,no matter of the flow direction.

JKVR-71611F Electric rubber-lined butterfly valve
  


JKVR-511 Series valve eccentric ball valve
Features
The eccentric rotary body has a simple flow path and a very small flow resistance. It combines the advantages of the linear stroke valve and the advantages of the angular stroke valve. It has excellent performance and wide adjustment range and control precision. It uses a rotary motion mode in which the eccentic cores is tucked or offset from the seat ring to eccentric rotary valves is ideal for applications where scouring and wear are high. It has high rigidity and output force, can work reliably under the rated pressure difference, realize precise flow control and long working life. It is one of the most advanced angular stroke control valves in the world.

JKVR-512  O- ball valve

JKVR-716 Series three eccentric butterfly valve

JKVR-717 Series low load light butterfly valve
Using  themiddle line structure of the metal and seal design. Metal seal seats are built around the disc to minimize seat leakage. This series butterfly valve is simple in structure, light in weight, mature in manufacturing technology and convenient in maintenance.


JKVR-71411F Series lining fluorine butterfly valve
Using the middle line fluorine structure. The valve body and valve plate are lined with PTEE of F46 and other strong corrosion resistant materials, can effectively avoid the corrosion of the valve with strong corrosive medium, and has good sealing performance. This series of butterfly .Valves are mainly used in chemical industry and other industrial processes of corrosive fluid control, is to adjust or cut off a variety of chemical corrosive media corrosive media ideal solution.


Features

The O-type ball valve is a right-angle rotary type shut-off valve. It is used with pneumatic actuators or electric actuators for remote control. It can also be equipped with a handle or a turbine for manual control. This type of valve is mainly used in pipelines. Cutting, distributing and changing the flow direction of the medium is a new type of valve that has been widely used in recent years.Its advantages are :

1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.

2.Tight and reliable. At present, the sealing surface material of the ball valve is widely used in plasyics and has good sealing performance. It has also been widely used in vacuum systems.

3. Easy operation, quick opening and closing, as long as it is rotated 90^o from full opening to full closing, which is convenient for long-distance control.

4. Easy maintenance, simple structure of the ball valve, the sealing ring is generally active, and it is convenient to disassemble and replace.

5. When fully open or fully closed, the sealing surface of the ball and the seat is isloated from the medium, and the medium will not cause erosion of the sealing surface of the valve.

6. Wide range of applications,from small to a few millimeters, up to a few meters. from high vaccum to high pressure can be applied.

JKVR-53Series three-way ball valve


Product range
The three-way ball valve is developed with advanced techonology at home and abroad. The standard ball core has two types of "L" type three-way double-port and "T" type three-port. By changing the relative angle between the core and the pipe, three pipes can be used. Different combination of fluid control, "T" type tunnel can play the role of split flow,"L" type channel plays a proportional role, suitable for the eatio adjustment and control of liquid, gas, steam and other media.
