CRYOGENIC CHECK VALVE MANUFACTURERS IN INDIA

Speciality Valve is a prominent Cryogenic check valve manufacturers in India, delivering specially designed ultra-low temperature valves of superior quality. Our cryogenic check valves are specifically designed and constructed to operate liquefied gases and ensure leak-proof, safe service in cryogenic environments.

Why Cryogenic Are Check Valve Required?

Cryogenic check valves are essential in cryogenic liquid-handling systems such as LNG, liquid oxygen, nitrogen, and helium. Backflow prevention by check valves prevents backflow from occurring in pipelines, and the one-way flow allowance protects delicate equipment. Check valves play an essential role in offering safety and efficiency at the extremities of temperature conditions.

Key Parts of Cryogenic Check Valve:

1) Extended Bonnet: Avoids thermal shock and protects internal parts
2) Valve Body: Construction using stainless steel or cryogenic-grade
3) Disc/Flap: Automatically opens on flow and automatically closes upon back flow
4) Spring (Optional): Assists in rapid shutoff
5) Seal and Seat: Resiliently seals to achieve close sealing at cryogenic temperatures

How Cryogenic Check Valves Work?

These self-actuating valves need no external control. When flow is in the forward direction, the disc swings or opens up. When flow is in the backward direction, the disc quickly moves towards the seat to avoid backflow. The longer bonnet keeps the sealing portions warm and does not allow freezing or damage.

Benefits of Cryogenic Check Valve:

1) Avoids backflow in cryogenic systems
2) Specialized for very low temperatures
3) Low pressure drops and quick operation
4) High reliability with low maintenance
5) In the majority of mounting positions

Functions of Cryogenic Check Valve:

1) One-way flow control
2) Protection of pumps and compressors
3) Isolation in gas transfer systems
4) Safety guarantee in cryogenic pipelines
