1. Top Entry Cryogenic Trunnion Mounted Ball Valve Structure: This structure allows the valve to be maintained online, improving the convenience of use.
2. Extended Valve Cover Design: prevents condensed water from flowing into the insulation layer, ensuring the normal operation of the valve in low temperature environment.
3. Valve Stem live-loaded Seal Structure Design: This design improves the sealing performance of the valve and ensures good sealing effect under various working conditions.
4. Special Design of Valve Seat Assembly: including detachable valve seat structure to ensure reliable sealing and easy maintenance.
5. Valve Cavity Overpressure Relief Design: ensure the safe operation of the valve under high pressure environment.
6. Valve Stem Anti-settling Design: prevents the valve stem from settling during operation to ensure the stability and reliability of the valve.
7. The Extended Valve Cover Has a Drip Tray Design: it effectively prevents condensed water from flowing into the insulation layer and protects the internal structure of the valve.
8. Fire-resistant, Anti-static, and Anti-stem Blowout Functions: ensure the safe use of the valve under extreme conditions.

Designed specifically for deep-cold media such as LNG and liquid oxygen, this valve features an austenitic stainless steel body that undergoes special deep-cold treatment to ensure reliable sealing and operational performance under extreme conditions of -196℃. The valve stem adopts an extended neck design and is equipped with a vacuum insulation structure, effectively blocking the transmission of cold energy. The valve can be equipped with either a flat seal or a conical seal structure, allowing for selection based on different pressure ratings, and is suitable for precise flow control in liquefied natural gas storage and transportation, air separation equipment, and low-temperature chemical systems.
The low-temperature gate valve is a type of equipment used for full opening and full closing operations. The opening and closing element of the low-temperature gate valve is a gate plate. The movement direction of the gate plate is perpendicular to the flow direction of the fluid. The gate valve can only be operated in full opening and full closing positions, and cannot be used for regulation or throttling. The gate plate has two sealing surfaces. The most commonly used type of gate valve has two sealing surfaces forming a wedge shape, and the wedge angle varies with the parameters.
The DBB Ball Valve (Twin Ball) requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
