The wafer style butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal; i. e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve.
We are dedicated to exclusively serving the Distributor, the Reseller, and the Qualified O. E. M, keeping our overhead low, our expertise high, and our service superior, thus making our product offering technically attractive and very competitive to our partners.
