Cast iron flange butterfly valve PN16

Cast iron flange butterfly valve PN16

XUVAL centric butterfly valves with fixed liner feature an outstanding seating concept. The rubber is injection molded directly on the valve body forming a permanent bond. Consequently, there is no risk of deformation or dislocation of the liner making the valves suitable under vacuum conditions. The combination of the profiled disc edge and the excellent XUVAL rubber quality ensures maximum durability of the liner.

Cast iron flange butterfly valve PN16

The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. And only need to rotate 90° can quickly open and close, simple operation, and the valve has good fluid control characteristics. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. Within the cylindrical channel of the butterfly valve body, the disc butterfly plate rotates around the axis, and the rotation angle is between 0°~90°. When rotating to 90°, the valve plate is fully open. When the flange butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated through the valve is very small, so it has better flow control characteristics. Butterfly valve has elastic seal and metal seal two types of seal. Elastic sealing valve, sealing ring can be inlaid on the valve body or attached to the butterfly plate peripheral.


Characteristics:

The main features of the flange butterfly valve are:

1. small and light, easy to disassemble and repair, and can be installed in any position.

2. structure is simple, compact, operation torque is small ,90° turn on quickly.

3. flow characteristics tend to straight line, good regulation performance.

4. The valve stem is connected with the inner pin plate without possible leakage.

5. the outer circle of the butterfly plate is spherical shape, which improves the sealing performance and prolongs the service life of the valve.

6. seals can be replaced and sealed reliably to achieve two-way sealing.

7. butterfly plates can be sprayed on a customer's request, such as nylon or polytetrafluoroethylene.

8. the valve can be designed as flange connection and pair clamp connection.

9. drive mode can choose manual, electric or pneumatic.


The flange butterfly valve is suitable for temperature ≤120℃ or ≤150℃, nominal pressure ≤1.6 water supply and drainage, sewage, food, heating, gas, ship, water, electricity, metallurgy, energy system and light spinning, especially for two-way sealing and valve body corrosion prone occasions, for regulating flow and closure media.
