Product Detail
UNIQUE full forging high temperature and high pressure bellows gate valve and globe valve advantages
1. The valve body and cover are connected by pressure self-sealing structure, wedge-shaped sealing ring (graphite clip stainless steel wire) and four-open ring combination;Force the sealing ring under high pressure deformation to achieve reliable seal, the higher the pressure the more reliable sealing.
2, metal bellows, key components of the bellows seal bottom end with stem adopts automatic seam welding welding, the upper connection plate automatic welding seam welding, between the fluid and the valve stem to form a protective barrier, to ensure that the valve stem zero leakage.
3. Reasonable stuffing box design, using the combination of graphite, flexible graphite packing and two ends packing, to ensure that the valve has no external leakage and meets the environmental protection requirements.
4. Stem reverse sealing design can be used in special case to replace packing.
5. The sealing surface of the seat is welded with cemented carbide to ensure long working safety and reliability.
6. The manual switch part adopts the structure of thrust bearing to enable the valve to open quickly and close easily and easily.
