with the ventilation structure and characteristics of pneumatic valve gate valve:
, well-selected materials, in line with the relevant standards at home and abroad, materials of high quality in an all-round way.
, conform to the requirements of domestic and international advanced standard, reliable sealing, excellent performance, beautiful appearance.
and reasonable advanced sealing pair matching, the ram and pneumatic valve seat sealing surface with different hardness of too stand ( Stellite cobalt-based hard alloy surfacing and become, reliable sealing, high hardness, wear resistance, high temperature resistance, good corrosion resistance, abrasion resistance, long service life.
ammonification, pneumatic valve rod by conditioning and surface processing, good corrosion resistance, abrasion resistance and abrasion resistance.
, adopting the wedge gate structure, large diameter setting thrust bearing, friction small, and is equipped with impact handwheel, easy opening and closing.
and can be used in a variety of piping flange standard and flange sealing surface forms, can meet the needs of all kinds of engineering and the user requirements.
