Speciality Valve is a renowned Cryogenic Check Valve Manufacturers in India, with high quality valve designed for efficient and safe control of flow in extremely low temperatures. Our cryogenic check valve are constructed to manage liquefied gas and cryogenic liquid with highest dependability and durability. 

A cryogenic check valve is a check valve designed to operate in cryogenic service involving liquefied gases such as LNG, liquid oxygen, nitrogen, hydrogen, and helium. It provides unidirectional flow while automatically preventing backflow to safeguard pipeline and equipment in cryogenic systems operating at temperatures of up to -196°C. 

Parts of Cryogenic Check Valve 

1. Body: Constructed from stainless steel or cryogenic-grade alloys for resistance to temperatures. 
2. Disc/Flap: Travels to open or close the valve according to pressure. 
3. Seat: Ensures a tight seal to avoid reverse flow. 
4. Spring (in spring-loaded designs): Provides instant disc return to the closed position. 
5. Extended Bonnet: Insulates the stem and operating mechanism from cryogenic temperatures. 

Working Mechanism 

The cryogenic check valve is pressure-differential-operated automatically. When upstream pressure is greater than downstream pressure, the disc opens to permit flow. Upon reverse flow or pressure loss, the disc resets automatically to the seat, inhibiting backflow. The longer bonnet keeps the valve in working condition even under very cold operating conditions by minimizing frost and thermal stress on the moving components. 

Benefits
