Providing the best products, the most perfect service with the most reasonable prices are our principles. We believe in quality over quantity.

Triple eccentric butterfly valve to withstand high temperature, must use a hard seal, but large leakage;To zero leakage, soft seal must be used, but not resistant to high temperature.In order to overcome the double eccentric butterfly valve this contradiction, and the butterfly valve for the third time eccentric.The structure characteristics of the double eccentric eccentric axis of the stem position at the same time, make the butterfly plate type sealing face of the cone axis deflection in the cylindrical axis of ontology, that is to say, after the third eccentric, butterfly plate sealing section is no longer true circle, but the ellipse, and so the seal face shape asymmetry, tilt to the center line of the ontology, on the other side is parallel to the centerline of ontology.The biggest characteristic of the third eccentric is fundamentally changed the seal structure and seal position is no longer, but the torque seal, namely not rely on the elastic deformation of the seat, but completely rely on the seat of the contact pressure to achieve sealing effect, thus solved the problem of metal seated zero leakage at a stroke, and because of the contact pressure and the medium is proportional to the pressure, resistance to high pressure high temperature is solved.

Our company has a quality assurance system have been established for Wafer Triple Eccentric Metal Seat Electric Regulating Butterfly Valve (GAD973W). As operation principle is 'be market-oriented, good faith as principle, win-win as objective', holding on 'customer first, quality assurance, service first' as our purpose, dedicated to provide the original quality, create excellence service, we won the praise and trust in the industry. With a rigorous working attitude, strong technical force, advanced manufacturing technology, and complete quality inspection equipment, our products not only excellent in performance, but also superior in appearance and quality.
