The valve which be used above temperature -46 Celsius is called general valve. Oct PN25 DN800 Di-directional Triple Offset Butterfly Valve Oct Protection Grade And Explosion-proof Grade Of Valve Actua... IP ( international protection ) protection grade of actuator indicate a grade of water-proof and dust-proof for electric equipment, general IP protection grade include IP 55, IP 65, IP 68, etc., here explain the means of this grade, take IP55 for example : IP is a mark "internation protection", first number 5 is a mark number, and 4 is a second mark number. The first mark number indicates contact protection and dust-proof protection level, and the second mark number indicates water-proof protection level. The higher the level, the more stringent the environment can be used. Sep Pneumatic Actuated Low Temperature Butterfly Valve ZFV provided butterfly valve be used in low temperature, which is cryogenic butterfly valve. Generally the cryogenic butterfly valve use extended shaft/gland design . the length of the extension will be sufficient to maintain the stem packing at a temperature high enough to permit operation within the normal temperature range of the packing material. The general packing material is graphite, the normal temperature of packing should be 8 degree C and higher. There are different stardards mention different requirement length of extention, cover using temperature range from -46 degree to -196 degree C even lower temperature
