PTFE lining butterfly valve

Fluorine lined butterfly valve is used all along with the rotation of the butterfly valve stem to open and close pieces of board to achieve the valve opening, closing and regulation.

PTFE Lining Butterfly compact, light weight, open and close rapidly, fluid resistance is small, cut off and throttling can be applied, but also has a good flow in vitro. Compared with the other valves, butterfly valves to reduce the weight of an average of 30-50%. Butterfly board rotated 90 degrees, can be realized Kai, closed process, because both sides of the butterfly board shaft by the media, are approximately equal force, torque the contrary, so hoist a smaller force.

The basic structure:
The basic types are the two pairs of clip-type and flange type, both with the right combination of a two-piece valve body, valve seat and valve lining integration, is a mandatory full-lining type butterfly valve seal, valve job, only the overall contrast fluorine plastic bush with media contacts to ensure reliable corrosion resistance: the valve closed, the butterfly plate extrusion bushing to form a seamless seal.

Features:
1, for the entire centerline butterfly valve plate and valve seat within a concentric circle of 360 degrees (middle), with two-way sealing function, pressure, flow rate can be adjusted freely.
2, the use of advanced proprietary technology for processing lined butterfly board, fluorine plastic and metal matrix seamless closely and effectively to make mezzanine row bubbles to eliminate from layer cracking and other process defects.
3, valve seat 360-degree flexibility to increase the radial force sealing pad, applied radial resilience, automatically adjust deformation, reliable and long-term use state certification within the leak-free medium.
4, butterfly board, the next multi-level load flexible shaft seal, automatic compensation to achieve sealing, so that the upper and lower shaft seal constitutes a seamless seal to ensure leak-free medium.
