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 engineering ceramics 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 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.
6. 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.
