GMK Full Lined Butterfly Valve

Butterfly valves with full linings are a versatile form of valve that can be used for shutting off or adjusting the flow of a fluid. The disc, located at the valve body’s geometric center, functions as the closure mechanism. The shaft runs from the disc through the top of the valve body and into a handle or actuator. Since the butterfly valve’s disc is always exposed to the flow, it causes a pressure drop even when the valve is closed. Butterfly valves are lighter than ball valves, allowing for faster shutoffs without the need for additional support. Butterfly valves with rubber seals open and close with a 90-degree turn of the disc. To regulate the rate of flow, they can be opened in small increments. This can be done manually, however, an actuator allows for more exact flow throttling. By installing positioners in the case of pneumatic and hydraulic actuators or modulating boards in the case of electric actuators, the flow rate of the actuator can be adjusted in small increments.

DESCRIPTION

Benefits:

One of the many benefits of butterfly valves is that they are able to:

With fewer moving components and a straightforward layout, it’s easier to keep in good working order and cheaper to fix if anything breaks.
Because of its wafer-like design and low weight, this valve may be purchased for a low outlay while yet being easily installed with minimal labor and pipe requirements.
It is capable of transporting mud with only a small amount of fluid being left behind at the pipeline’s outflow.
They seal well under low pressure and are simple to open and close.
The disc weighs much less than a ball would.
When compared to ball valves of the same diameter, butterfly valves require a significantly less supporting framework.

Concentric type or called middle line
Seat ring: NBR, CR, NR, EPDM, FKM, PTFE, PCTFE, FEP, PFA
Body lining: NBR, CR, NR, EPDM, FKM, PTFE, PECTFE, FEP, PFA
Seal with two-way function, pressure, flow can be allowed to adjust freely
The use of patented technology to have lined butterfly processing board, plastic, and metal fluoride matrix closely with seamless, efficient scheduling to make laminated bubble, since the elimination of layers, cracks and other defects in the process
Seat with 360-degree radial sealing force elastic pad back to exert radial force, the automatic adjustment of deformation, a reliable guarantee for long-term use of state media with no leakage. Butterfly board, under the shoulder-axis multi-level flexible sealing load to achieve automatic compensation sealed so that the whole constitutes a shaft seal without gaps vice to ensure that no leakage of media.
Top flange ISO5211 for optional
Sealing materials have the advantages of anti-aging, corrosion-resistant, long duration, etc
Strong wash and brush resistance and can fit bad working conditions
Long service life
