Overview:
1. The body and
bonnetlink forms: PN****4 using bolted bonnet;
PN*****0 using the pressure sealed cover.
2. Stem nut: under normal circumstances, stem
nut materials using ASTM A**9 D2, at the same time can be based on
user require the use of copper alloy materials, such as for large
caliber cut-off valve, rolling bearing, can effectively reduce the
cut-off valve open torque can easily switch
valve.
3. Stem design: the whole forging process, in
accordance with the standards to determine the minimum
diameter.
4. The valve cover gasket form: PN****4
cut-off valve adopts stainless steel graphite winding gasket; PN**0
globe valves are available in stainless steel graphite winding
gasket can also use a metal ring gasket; PN**0 cut-off valve can be
used metal ring gasket, PN**0 cut-off valve adopts the pressure
seal metal ring.
5. Stop valve structure features: bolted
bonnet, rising stemyoke and
lift stem metal cover.
6.Backseat
design: our company provides all globe valve seal design, under
normal circumstances, the carbon steel globe valve seat design USES
separate sealing structure, stainless steel valve's sealing face is
very reliable. Although have pour sealing according to the standard
API**0, but it's not as the basis of in case bring pressure change
filler.
7. Packing: usually adopt forming flexible
graphite as filler material, can according to user requirements to
provide PTFE or compound packing materials. Packing and stuffing
box contact surface roughness is 3.2 u m, can ensure that the valve
stem and packing interface bonding tightly but is free to rotate to
a precision machining of the valve stem sealing surface roughness
of 0.8 u m can ensure the valve stem seal.
8. The seat: carbon steel globe valve seat
usually using forged steel materials, valve seat sealing surface
spray welding carbide according to customer demand, NPS *0 or less
"by using separate thread screw-plug seat, if users need to weld
the seat structure are available; NPS *2 "cut-off valve adopts
welded seat structure or less; Stainless steel valve seat generally
adopt and or in the cemented carbide welding processing directly
after the seat on the body. If the user requirements, stainless
steel valve seat can also adopt separate thread screw-plug and
welded-in seat structure.
