WHY BELLOWS SEAL VALVES One of the most frequent and serious problems valves 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 constitute 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 often demand continual maintenance in accessibility creating particular difficulties. The bellows comply to conditions at high temperatures and are capable of withstanding over 10,000 cycles without failure.ApplicationHot oil system, steam system, hot and cold water system etc.Advantage1,Stem :2-part rising stem with outside roll-formed thread; stem coupling with bellows anti-torque device .2,Bellow : Multiple wall, fully flushed stainless steel bellows, secured against torsion, designed for 10,000 cycles; fully welded3,360º free rotation disc that allows the cleaning of impurities that can carry the fluid to make the closure on the different surfaces of the seat, at the same time, it does not transmit the vibrations to the valve stem.4,Conically shaped plug made of hardened chromium steel 1.4021/AISI 420, or hard-surfaced with stellite 6; body seat hard-surfaced with stainless steel 1.4370/ AISI 307 or stellite 215,Metal back seat with stroke limiter in open position and bellows anti-vibration device6,Full size safety gland packing made of pure graphite; can also be supplied in PTFE if requested7,Stainless steel camprofiled bonnet gasket coated with pure graphite, mounted in
tongue and groove bonnet flanges 8,Using coated sand casting technology, which can promise Zero trachoma, Higher precision, perfect surface .Technical specificationDesign standard: DIN 3356Face to face dimension: DIN 3202Flanged ends: DIN 2543-2545Test & inspection: DIN 3230Main part materialsNO. | Part name | Material |
