Low Temperature Liquid Nitrogen Dedicated Cryogenic Globe Valve Factory Direct, -196°C Deep Cold
Core Technical Requirements for -196°C Deep Cold Globe Valve
For ultra-low temperature media such as liquid nitrogen, dedicated cryogenic globe valves must meet the following design standards: the valve body material should be austenitic stainless steel or aluminum alloy with excellent low-temperature performance, which maintains good toughness at -196°C without risk of brittle transition. The bonnet must adopt an extended neck design to ensure the packing box is kept away from the cryogenic zone, preventing packing freezing and failure. The sealing surface is hardfaced with cobalt-based hard alloy, which maintains good wear resistance and sealing performance at ultra-low temperatures. All pressure-containing parts must pass -196°C low-temperature impact test certification.The main stop valve product names of China Stop Valve Network include:ANSI Flange Straight-through Bellows Globe Valve,Forged Steel Straight-through Globe Valve,Flange Straight-through Low Temperature Globe Valve,High Temperature and Pressure Power Station Electric Globe Valve,Oxygen-specific Globe Valve,Vacuum Isolated Straight-through Globe Valve,Y-type Jacket Insulation Globe Valve,GB Bellows Globe Valve.
Factory Direct Price Range
Currently, the factory direct prices for low temperature liquid nitrogen dedicated cryogenic globe valves generally range as follows: DN15 size approximately RMB 850-1,500, DN25 size approximately RMB 1,200-2,200, DN40 size approximately RMB 1,800-3,200, DN50 size approximately RMB 2,500-4,500, DN80 size approximately RMB 3,800-6,500. The specific price is influenced by valve body material (stainless steel 304/316/aluminum alloy), pressure rating (Class 150/300), seal type, and actuation method.
Factory Direct Advantages
Choosing factory direct procurement for cryogenic globe valves offers the following benefits: Eliminating middlemen reduces procurement costs by 20%-30%; Customizable extended bonnet length and connection dimensions; Direct technical selection support and cryogenic treatment process guidance; Bulk purchases enjoy better discounts and fast delivery.
Purchasing Suggestions
It is recommended that users provide medium type (liquid nitrogen/liquid oxygen/LNG, etc.), working pressure, and pipeline insulation requirements before procurement. Request -196°C low-temperature impact test reports and cryogenic treatment records from suppliers. Give priority to factory direct products that comply with BS 6364 or GB/T 24925 standards, and request quotes from at least three professional cryogenic valve manufacturers for comparison.
