Highlight: Wafer Butterfly Valve
Product introduction:
The wafer butterfly valve is stably connected between two pipeline flanges via double bolts, featuring a (streamlined)
structure, compact design, and light weight, composed of a few core components. It only requires a 90° rotation for quick
opening and closing, with a simple and efficient operation process, while having excellent fluid regulation performance. In
the fully open position, the thickness of the butterfly disc is the only obstruction for the medium flowing through the valve
body, resulting in extremely low pressure drop, ensuring its superior flow control effect. This butterfly valve provides two
sealing types: spring seal and metal seal. The sealing ring of the elastic seal valve can be installed on the valve body or
attached to the edge of the butterfly disc, adapting to different working condition requirements.
