La description

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.
