Key Features and Advantages

Extended Bonnet Design
Cryogenic globe valves feature an extended bonnet, which provides insulation and ensures that the packing remains at a temperature that prevents ice formation. This design enhances operational reliability and extends the valve’s service life in cryogenic conditions.

Low Emission Packing
To minimize leakage and environmental impact, cryogenic globe valves are equipped with low emission packing. This feature enhances sealing performance and ensures compliance with stringent emission regulations, making them highly reliable for gas and liquid applications.

High-Performance Sealing Surface
The seat sealing surface of cryogenic globe valves is constructed with a full stellite overlay. This provides good wear resistance, corrosion resistance, and durability, even under high-pressure and low-temperature conditions. The stellite overlay ensures a tight shutoff and long service life.

Pressure Relief Mechanism
Cryogenic globe valves incorporate discharge holes at the upstream end to prevent abnormal pressure buildup in the valve body and bonnet cavity. This safety feature reduces the risk of internal damage and enhances operational efficiency.

Stem Stability and Strength
A specialized structure is integrated into cryogenic globe valves to prevent stem instability. This design improves overall durability and ensures smooth operation, reducing the risk of failure in demanding cryogenic applications.

Wide Range of Operation Methods
Cryogenic globe valves support multiple operation methods, including manual handwheel, gearbox, electric actuator, pneumatic actuator, and hydraulic actuator. This flexibility allows integration into automated systems for enhanced control and convenience.

Comprehensive Testing and Certification
Each cryogenic globe valve undergoes stringent testing in an in-house, computer-controlled facility to ensure performance and reliability. Testing is conducted up to 24” in size, adhering to international standards to guarantee good quality and operational efficiency.

Applications
Cryogenic globe valves are widely used in industries requiring precise flow control at to the limitly low temperatures, including:
- LNG (Liquefied Natural Gas) Processing and Transportation
- LPG (Liquefied Petroleum Gas) Systems
- Air Separation Plants
- Chemical Processing Facilities
- Cryogenic Storage and Distribution
- Industrial Gas Production

Cryogenic globe valves provide a high-performance solution for industries operating in to the limit low-temperature environments. With robust construction, precise sealing, and a range of operational methods, these valves deliver safety, efficiency, and durability. Designed to meet international standards, cryogenic globe valves ensure reliable performance and long-term value in cryogenic applications.
