Product Description

Din standard bellows seal ptfe lined dn150 pn40 cast iron globe valve for steam
One of the most frequent and serious problems valve face is gland leakage,results in wasted and increased plant downtime . Apart from the high cost of energy losses, Gland leakages can also cause serious environmental , ecological and health hazards to plant workers and personnel , Leakage of sensitive material can also constitude to a fire hazard , explosion, or damage to equipment by corrosive material . Air entering the pipeline could produce inflammable explosive or poisonous mixtures. Gland packed valves ofen demand continual maintenance in accessibility creating particular difficulties . The bellows complies to conditions at high temperatures and are capable of withstanding over 10,000 cycles without failure.
