Pneumatic Ceramic Swing Feed Valves are specifically designed for pressurized and vacuum systems, including dense and dilute phase pneumatic conveying systems, discharge, and vent applications in steel plants and coal power facilities. These valves feature double ceramic sealing faces that are well-ground and polished, ensuring reliable sealing performance. They are ideal for replacing dome valves in ash system pipelines.

Product Features

» Non-Contact Cylinder Piston Rod: The cylinder piston rod does not directly contact the medium, significantly extending the cylinder's service life and allowing for higher operating temperatures without damage.
» Toughened Tungsten Carbide Sealing Faces: The valve's sealing faces are made from toughened tungsten carbide, providing excellent abrasion resistance and prolonged service life.
» Customizable Options: Available with customized structural lengths and connection sizes to meet specific requirements.
» Rotational Disc Motion: The valve disc's rotational motion prevents ash deposition on the sealing surface during operation, enhancing the valve's longevity.
» Floating Connection with Spring: The spring-loaded floating connection between the disc and disc seat ensures consistent sealing, compensates for thermal expansion and contraction, and mitigates wear on the sealing surface.
» Blow Sweep Port or Device: The valve body can be equipped with a blow sweep port or an automatic blow sweep device, depending on the operating conditions, to further enhance performance and reliability.
