Cryogenic Gate Valve Design

Cryogenic globe valves cryogenic gate valves nps 1 2 42 dn 15 1050 class 150 2500 pn 20 420 extended bonnet low emission packing stellite overlay on wedge and seat ring bleed hole between upstream and backseat to prevent the pressure increase of body cavity.
Cryogenic gate valve design. The cryogenic valves are available in gate and globe design configurations. Ladish valves is a premier manufacturer of stainless steel duplex and high nickel alloy gate globe check and ball valves located in houston texas for power speciality chemicals oil and gas lng refining and petrochemical pulp and paper mining and other related industries. All basic design features of velan cast steel gate valves are adapted to special service conditions at cryogenic temperatures. Expectation from cryogenic valves.
What is cryogenic in broad spectrum. What why of cryogenics. These valves are extremely versatile and are designed to operate effectively even in cases of a low valve pressure drop. Home products cryogenic valve cryogenic globe valve cryogenic globe valve camtech cryogenic valves are specially designed for gas treatment processes and storage and transportation of liquefied gasses such as lng liquid nitrogen oxygen.
They also feature a lightweight design making them perfect for the transportation of industrial gas. This means that these cryogenic gate valves can achieve minimal leakage rates not normally associated with this valve type. Test process setup requirements. Valves are designed with an extended body for use in cold services to 196 degrees c 320 degrees f.
Seat or disc with ptfe or pctfe. The gate valves are manufactured in stainless steel. Cryogenic specifications extended bonnets extends valve packing and operator away from cryogenic fluid allows operation in normal working temperature range cast forged or fabricated with seamless tube minimum extension lengths for non cold box cold box applications based on valve type nps and temperature design to worst case asme b16 34 wall thicknesses. 1 of 1 item.
Hence we should know about the specific low temperature which calls for cryogenic. These valves are required. The second design is the welded bonnet with a threaded and seal welded joint. Extended bonnets with sufficient gas column length usually specified by customer are supplied for all valves to keep stem packing at sufficient distance away from the cold fluid to remain.
Valve installation and orientation arrangements. This requirement is to ensure that a vapor space is formed under the valve. Please find your cryogenic gate valve in the product choice below. In general definition of cryogenics in physics is the construction and behaviour of materials or any item at very low temperatures.
Prevent stem unstable structure optional soft seal.
