Cryogenic Globe Valve
Introduction
F-V, a market leader in providing valves for difficult services, produces Cryogenic Globe Valves that meet MSS-SP70 specifications. These valves are used in a variety of applications, including highly corrosive environments in chemical and petrochemical plants, chlorine gas, semiconductor, pulp and paper industries, crude and diesel fuel, fresh water and seawater in shipbuilding or on existing cargo, tanker or passenger ships, food applications, LNG liquefaction, LNG tanker ships, and LNG receiving terminals.
Features of Cryogenic Globe Valves
Cryogenic Globe Valves are designed to operate at cryogenic temperatures, which can range from -196°C to -269°C. These valves are made of materials that can withstand the low temperatures and high pressures of cryogenic fluids. The valve body and bonnet are usually made of stainless steel, while the stem and disc are made of materials such as stainless steel, bronze, or aluminum bronze.
Another important feature of Cryogenic Globe Valves is their ability to prevent leakage. These valves have a special design that allows them to create a tight seal between the valve body and the disc, which helps to prevent any leakage of cryogenic fluids.
