Cryogenic Gate Valve


Design Feature

1: Full bore or reduced bore

2: Integral body structure

3: Double Block & Bleed, Double isolation and bleed(DIB-1&DIB-2)

4: Fire safe design(API 607)

5: Blowout-proof system

6: Anti-static design

7: Self cavity relief

8: Fugitive emission testing(optional)

The ball is fixed by trunnion and stem for size 4” &smaller. Trunnion plate support for size 6” & larger


Blow-out proof stem:

The stem is made separately from the ball with integral T-type round shoulder, retained by bland .(other designs are Available on request)


Anti-static device:

Spring plus graphite type anti-static device are applied between the ball ,stem, gland Flange and body to keep the electrical Continuity between all the metallic components . 

And ensure the resistance lower than the most severe service requirement.


Sealing Options

Soft seat: Metal to Metal O-Ring seal

Simple structure reliable sealing Applicable to particulate Reliable sealing low torque meet customers' high wide application low cost. 

Media conditions sealing reliability and low torque requirements.
