> Bolt connected valve bonnet, rising stem, lifting stem, metal seal.

> Connection of valve body and valve bonnet

The valve body and valve bonnet of globe valves within Class150~Class900 ( PN10~PN160) pressure ratings typically employ a stud-and-nut connection design.

> Actuation Type

Generally, hand-wheel actuation, worm gear actuation, gear actuation, electric and pneumatic actuation are used.

> Packing

Standard packing is flexible graphite formed packing; PTFE, metal wire reinforced flexible graphite formed packing or composite packing can be selected according to actual requirements.

> Backseat structure

The entire series is equipped with a backseat structure. Carbon steel valves generally have replaceable backseat ring, while stainless steel valves feature a formed backseat through integral machining or overlay welding; The backseat structure ensures reliable sealing when the valve is fully open.

> Seat

Carbon steel globe valves use forged valve seats with spray-welded, user-specified alloy sealing surfaces. For NPS≤10 and DN≤250, the valve seat are default threaded connections  to the valve body,, with welded connections also available.. Valves with NPS≥12 and DN≥300 typically employ welded connections. Stainless steel globe valves   generally feature integral seats  (machined from the valve body) or overlay-welded alloy directly on the body. Threaded or welded seats may also be configured based on requirements.

> Design of valve stem

The valve stem is manufactured as an integral forged component, with its minimum diameter strictly adhering to industry standard specifications.
