High pressure flange connection USES and characteristics of pneumatic valve steel gate 3

high pressure flange connection steel brake and the structure characteristics of pneumatic valve. High pressure pneumatic valve flange connection of steel gate in accordance with the requirements of domestic and international advanced standard, reliable sealing, excellent performance, beautiful appearance. 。 Ram and pneumatic valve seat sealing surface with iron base alloy welding or state department ( stellite） Cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, corrosion resistance, good abrasion resistance, long service life. 。 Pneumatic valve pneumatic high-pressure flange gate valve stem after quenched and tempered and surface nitriding treatment, has the good corrosion resistance and abrasion resistance. 。 Pneumatic valve adopts the wedge type flexible disc brake structure, large diameter set the rolling bearing, friction small, easy opening and closing. 。 Can be used in a variety of pipe flange and flange seal face type, can meet the needs of all kinds of engineering and the user requirements. Brake pneumatic valve product use high pressure pneumatic valve flange steel gate is suitable for the nominal pressure PN. ~。 Mpa, working temperature - ℃ ~ ℃ under various working conditions such as petroleum, chemical industry, power plant of pipeline, cut off or connect medium.
