API Full Lug High Performance Butterfly Valve Metal Seat

API Full Lug High Performance Butterfly Valve Metal Seat

Product Details

The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by rotating 90°, and the operation is simple, and the valve has good fluid control characteristics. The butterfly valve's disc is mounted in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully open. When the flange butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics. The butterfly valve has two sealing types: a spring seal and a metal seal. Elastomeric sealing valve, the sealing ring can be mounted on the valve body or attached to the periphery of the disc.

Product performance:

1. The lug type high performance butterfly valve has a unique structure and double-sided pressure bearing design.

2. High-performance butterfly valve full range of pressure ring patented structure, ultra-reliable sealing.

3. Butterfly valve full range of anti-static guiding device structure, ultra-small operating torque.
