Feature

 

Structural style

Natural Gas Pipeline Gate valve adopts OSY and BB(bolted bonnet), Rotate-Rising stem and non-rise hand

wheel which is international current gate valve structure.

 

Body and Bonnet

Natural Gas Pipeline Gate valve Body and bonnet design is according to precise calculation in order to realize

good strength,rigidity and flow capacity. There designs a upper seal support on bonnet that makes packing

seal more reliable in the valve full open condition, also replace packing conveniently.

 

Disc

Adopting H-type elastic single disc to suit the valve body deformation and keep sealing

reliable,which avoids valve hard to be opened due to disc overloads. So it is suitable for

steam and other high temperature medium.

 
Seat
For different pressure and specification, there are several seat forms below:

2.Directly bead welding sealing surface material on body.
3.For SS valve ,popularly seat sealing surface will be processed molding directly on body.
 
Stem and stem nut
Natural Gas Pipeline Gate valve Stem connects disc by T-slot, the whole forging forming
T-shape stem assures enough connection strength. Stem is operated by hand wheel drives stem nut, the transmission
between stem and stem nut uses suitable fit clearance and unique dentoform correction to ensure flexible valve drive.
Top assembling stem nut keeps stem and disc never drop down even if discharging the hand wheel when valve is open.
For the large diameter gate valve,the thrust bearing is designed in the place of stem nut.
 
Packing and packing spacer ring
The size and quantity of packing meet the standards and ensure reliable sealing. Packing is graphite( free from asbestos).
Packing spacer ring can be provided when customers require.(no packing spacer ring in standard product).
