ZECO butterfly valve for cryogenic service is designed for tight shut off and throttling service. The disc movement is Triple offset .This eliminates concentrated wear points on the sealing ring and extends it’s lifetime. Standard body patterns are flanged and butt welded types. Butt welded type has extended body to prevent heat conduction to the sealing area during welding installation. An inspection door on top of the body enables easy inspection, maintenance and replacement of inner parts without the need to remove the valve or to cut the pipe. To prevent internal stress in the bonnet during the cool-down period, all bonnet joints are bolted. This bonnet is extended to ensure that the gland area remains free from freezing even for temperatures down to -196˚C. The valve can be installed with the shaft in any direction. The topflange drilling is according to ISO 5211 standards to fit a large range of gears and actuators.

Features of Cryogenic Butterfly Valve: Cryogenic by design Cryogenic Butterfly valves are specifically designed for sub-zero line temperature services. These valves handle cryogenic fluids efficiently and reliably with minimum maintenance requirements Compact for better temperature control The compact size of the wafer and lug style valves permits minimum temperature stabilization times on either line heat-up or cool-down. Application flexibility The stainless steel materials of construction provide for maximum service flexibility and media applications. Designed for actuation and easy adjustment Integrally welded shaft and bonnet extensions enable valve actuators to be mounted well above pipeline insulation and provides for easy adjustment of the stem packing gland pressure Material of Cryogenic Butterfly Valve No Part Material 1 Body ASTM A351 CF3M 2 Seal Ring Graphite + SS316L 3 Retainer Flange ASTM A182 F316L 4 Pin ASTM A276 316L 5 Disc ASTM A351 CF3M 6 Stem ASTM A276 316L 7 Stem Packing Graphite 8 Stem Beating SS316L + R.TFE 9 Bolt ASTM A193 B8M 10 Nut ASTM A194 8M 11 Yoke ASTM A351 CF3M Related products 8″ Butterfly Valve Read more ENQUIRY!
