Bellow Seal Gate Valve

Product Detail:

What is Bellow Seal Gate Valve?

Bellow Seal Gate Valve is operated as an obstruction between fluids and the air. At the same time, the valve can prevent fluids leaking to the air and guarantee zero leakage of pipelines. The bottom of bellows is welded to the valve stem of the bellow seal globe valve to avoid process fluids eroding the valve stem.

NORTECH advantages of Bellow Seal Gate Valve

What is the Static Balancing Valve used for?

1.Metal bellowsseal the moving stem and increase durability of packed stem seal valves 2.Bellow provide a barrier between the stem at its point of entry through the pressure boundary and the process fluid within the valve, to eliminate stem leakage 3.An anti-rotation device is provided in the bonnet to ensure bellow does not get twisted during assembly and disassembly or by vibration 4.Bellow-sealed valves are usually leak tested using a mass spectrometer to detect leakage rates below 1x10E-06 std.cc/sec. 5.Bellow-sealed bonnets are backed up with a standard stem packing set and a leakage monitoring port between the bellows and the packing in order to prevent catastrophic release of hazardous fluid in the event of a bellows leak.
