Product quotation standard：

design and production：JB/T3595
construction length：GB/T15188.1
Pressure temperature rank：GB/T3595
testing and inspection：GB13927 JB/T9092

Product use：

vacuum isolates Globe valve is suitable for Nominal Pressure PN4.0~10.0Mpa, Operating temperature ≤200℃ on thermal power station backwater condenser system channel, in cut-off or connection agent. Is suitable the medium is: Water, steam and so on.

Product mix characteristic：

1.Product according to JB/The T3595 standard design manufacture, satisfies the power plant equipment necessary operation requirements。
2.Designed the vacuum seal structure padding room, the isolation vacuum has been reliable.
3.Stem after the quenching and tempering and the surface nitriding, has the good corrosion resistivity, anti-abrasion and resistance to wear.
4.The flange filling piece uses the compound materials, the expansion coefficient is big, the aeroseal performance is good, guaranteed the system and the atmosphere isolate reliably.
5.Pours seals uses the stainless steel screw joint seal place or the main body built-up welding austenite stainless steel becomes, pours seals reliably. The padding replacement and the service may not carry on in the engine off situation, facilitates does not affect the system movement quickly.
