Features of Bellow Sealed Valves |
|
| |
|
Bellow Seal prevents leakage of sensitive media which constitute high fire risk. Our bellows are capable of withstanding 20,000 cycles and above without failure under pressure. Gland packed valves often demand continual maintenance - inaccessibility creating particular difficulties.
Steam at pressure of 150 p.s.i. escapes through a stem / gland clearance of 1 / 1000th of an inch at a rate of 24 lbs per hour. Best suited valve for all critical applications. |
