Cryogenic Check Valve Forged Steel Material Good Sealing Performance

Good quality Trunnion Ball Valve for sales
Good quality Trunnion Ball Valve for sales
Really good performance valves with completitive cost, I hope both parties will work for longer.

—— Rashid Lodhi

Good after sale service, I really appreciated that the each step maintenance instruction is very detailed and good for my end user even they do not know valves at all.


Wesley from Kelite Group was very perfessional on handling our FAT, 3.2 certification, 3rd party inspection and accompany my clients to aduit each supplier, also a good driver for lasts more than 12 hours driving to pick up my clients, impressive!

Kelite is specialized in manufacturing API Forged Steel Cryogenic Lift Check valve. The structure of Cryogenic Lift check valve is very similar with Globe valve with the disc doing up and down movement during valve's operation. It has a reliable sealing but with relatively high flowing resistance. Stainless steel Cryogenic Check valve is suitable for small size area. Cryogenic Lift check valve could be in through type or vertical type. The through type lift check valve could only be installed on horizontal pipeline, while the vertical type lift check valve is usually on vertical pipeline.


API Forged steel cryogenic lift check valve is used for inflammable and explosive liquid medium such as ethylene, liquid oxygen, liquid hydrogen, LNG, liquefied petroleum product and etc. As forged steel cryogenic lift check valve is an automatic valve realizing the opening and closing all by the force of mediu, so there is no need of long neck structure. All the components of cryogenic lift check valve would be immersed in cooling medium for 2-8 hours after raw machining to release the stress and ensure its cryogenic property.


API Forged Steel Cryogenic Lift Check valves are suitable for use on various kinds of pipeline from Class150 To Class1500, PN16 To PN250 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc.


Working Principle of API Forged Steel Cryogenic Lift Check Valve: When the medium passing through the valve from the inlet port, the valve would open if the pressure force of medium exceeds the gravity of disc. However, when the pressure force of backflow medium plus the force of disc's gravity is bigger than the medium force from the inlet side, the valve would close itself to prevent the backflow.


API Forged Steel Cryogenic Lift Check Valve product features

The valves has the features of Good sealing, reliable, safety and long life span.

API Forged Steel Cryogenic Lift Check valves developed by Chaoda have following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.

Other remarks The extension dimensions of valve stem and bonnet may vary according to different temperature ratings.
Other remarks 2 As valves subject to a temperature ≤-101℃ shall be protected against subzero deformation, the main parts are subzero treated.
Other remarks 3 The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve.
Other remarks 4 The friction between sealing faces is smaller during opening and closing, facilitating a longer service life.
Other remarks 5 The valve clack is of taper, needle, ball and parabola types, and can be used to adjust the flow rate.
Other remarks 6 SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing.
Other remarks 7 Rising stem structure, making the valve switch position be clear at a glance
Other remarks 8 The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced.
Other remarks 9 Small switching moment, reliable sealing
Other remarks 10 The valve clack can be machined into parabola, spherical, needle shapes, etc. according to the requirement of customer. It can be used for adjustment (rough adjustment) on pipeline.
Other remarks 11 Short stroke is suitable for application at positions subject to frequent opening.
Other remarks 12 Y-shape stop valve – the streamline flow pass has a very high flow coefficient, and can maximally reduce the pressure drop through the system.
Other remarks 13 Through improving the structural design and selecting reasonable packing structure and qualified packing supplier, the valves can meet the Class A sealing test requirements of ISO 15848 FE.
