Product Details

Product Description

Product Description
FREE-VALVE brand Hard Alloy Seated Rotary Double Disc Gate Valves are designed for pressurized and vacuum systems including dense and dilute phase pneumatic conveying systems, discharge and vent applications in steel plant and coal power. The whole of ceramic sealing faces of the valves are well ground and polished, which is ensure a reliable sealing performance of the valve.
Features
1. The cylinder piston rod does not contact with the medium directly, which greatly prolongs the service life of the cylinder and has a higher service temperature without damaging the cylinder.
2.The sealing faces of the valve are made of toughened hard alloy with good abrasion resistance and prolonged service life.
3.Product with customized structural length and connection size is available.
4. The valve disc rotational motion can avoid the ash deposition on the sealing surface during opening and closing, so the valves have much longer service.
5.The rotation structure with shorter stroke makes and the whole of hard alloy sealing faces of the valves, which are ensure a reliable sealing performance of the valve.
6. The valve body outlet end adopts slant structure, which is advantageous to the medium entering the valve cavity to fall automatically, preventing the medium in the valve cavity accumulation and causing the valve not to open properly.
7. The spring between the disc and disc seat is loaded with a floating connection. The spring force of the disc always matches the valve seat, ensures the sealing of the valve, and also helps to compensate for expanding when heated and contracting when cooled ,and sealing surface wear.
