Jacketed Gate Valve

Jacketed Gate Valve is largely used to sustain process media temperature during process to keep fluids at a lower viscosity to operate valve smoothly.The jacketed gate valve can be full jacketed or half jacketed design.Each full jacketed gate valve body construction replace by adding minimum one size higher flanges to achieve proper tighten space of bolt and nut.

As example: For full jacketed gate valve size DN80 x DN100 (3" x 4"), the nominal bore is DN80 (3") and the flange size is enlarged to DN100 (4"), which allows enough space for bolting clearance after jacket fabricated (welded) on modified valve body. These types of jacketed gate valve termed as a Full Jacketed Gate Valve. If it is half jacketed design, the flange of the jacketed gate valve is not enlarged.

Jacketed Gate Valve with steam or hot oil in jackete is mostly used in Polymer, Bitumen, Liquid Asphalt, Coal tar, Lactum, Highly Viscous Media, Molten Sulfur or Sulphur, Resin, Chocolate,Glue. All jacketed gate valve has standard inlet & outlet connection for steam or hot oil circulation. Jacket connection can be threaded (BSP / NPT female) or flanged end.

Jacketed Gate Valve is available with body material WCB, LCC/LCB, SS304/316/304L/316L-CF8/CF8M/CF3/CF3M, Alloy20-CN7M, NACE MR-0175, Duplex Steel, Super Duplex Steel & Hastelloy C22/C276 Grade.
