Didtek Hot Oil Transmit Regulating Disc Bellow Globe Valve

Application & Function:
Didtek DIN Bellows Globe Valve feature a formed multi-ply bellows welded to the stem and to the bottom of the bonnet,creating a hermetic seal or impermeable barrier. Bellows are available in many materials for virtually all corrosive chemical applications.
Heat tranfer media: hot oil is commonly used in industries such as synthetic fibres/ POY(Partially Oriented Yarn). However,there is always a risk of fire due to hot oil spillage on highly inflammable chemicals. Here,bellow seal valves can stop the leakage.
