Product usages

Vacuum isolated straight-through globe valve is applied to nominal pressure PN4.0 ~ 10.0Mpa, operating temperature ≤ 200 °C fire power plant backwater condensate system pipes, worked as cutting off or connecting to the media. Applicable medium: water, steam and so on.

Product structural features

1. The design and manufacture is according to JB/T3595 standard, to meet the requirements of power station equipment matching application.
2. the vacuum sealing structural packing box is designed, with reliable vacuum isolation.
3. after tempering and surface nitriding treatment, the stem has good corrosive resistance and anti-friction performance
4. Flange gasket uses composite materials, with large expansion coefficient, good gas-sealingt performance, ensuring a reliable isolation of system and atmosphere.
5. The inverted sealing adopts stainless steel thread connecting sealing seat or bead welded by austenific stainless steel, and is reliable. The replacement of packing and maintenance can be processed without stopping the operation.
