CRYOGENIC CHECK VALVE MANUFACTURERS IN INDIA

Speciality Valve is one of the most trusted Cryogenic Check Valve Manufacturers in India, providing precision-engineered solutions for cryogenic operations across industries. Cryogenic operations require highly specialized valves capable of handling very low temperatures and providing performance and safety.

What is a Cryogenic Check Valve?

A cryogenic check valve is a non-return one-way valve appropriate for ultra-low temperature service, commonly below -196°C. It permits the flow of fluid in one direction and rejects backflow to shield equipment and ensure system integrity in cryogenic pipelines.

Why Needed?

For applications in liquefied gases such as LNG, helium, oxygen, and nitrogen, backflow can damage equipment, lead to leaks, or even pose safety risks. Check valves are required to prevent backflow in applications such as cryogenics where safety and reliability are major concerns, even at very low temperatures.

Components of Cryogenic Check Valve:

· Body: Constructed from stainless steel or special alloys that can be used for cryogenic service

· Disc: Constructed to open during forward flow and close during reverse pressure

· Bonnet: Lengthened for insulation and protection against heat

· Spring: Helps the valve to close rapidly to avoid reverse flow

· Seat and Seal: Crying-grade soft seat or metal seats for close shut-off

Working Principle:

It is operated by pressure of the fluid greater than the cracking pressure. The disc goes back automatically to the closed position upon flow cessation or reversal, hence avoiding backflow. The bonnet extended helps to give protection to the stem to be isolated from cold process media.
