Forged Steel Bellows Seal Globe Valve Descriptions

Forged steel bellows seal globe valve solves the stem gland packing leakage, which results in wasted and increased downtime for the factory. Apart from the high cost of energy losses, gland leakages can also cause serious environmental, ecological and health hazards to factory workers. The leakage of sensitive materials can also constitute to the fire hazard, explosion, or damage to equipment by corrosive materials. If the leaked air enters into the pipeline, it could produce inflammable explosive or poisonous mixtures. Gland packed valve often requires continual maintenance in accessibility creating particular difficulties. Flowspec Luokai manufactures the forged steel bellows seal globe valve applicable to working conditions of high temperatures, withstanding over 10,000 cycles without failure.
