Yes, a seal that’s softer than metal can also be tougher than metal.

Once upon a time, a metal pressure seal was a standard component for every high-pressure valve manufactured worldwide. But when power plants began cycling multiple times a day and going longer between outages, it changed the whole ball game.

Metal can’t take high-cycle activity. When a seal wears out from cycling, it leaks and does major damage to the pressure seal cavity. When they gall and weld themselves into place, they become one with the valve and removal can require a chisel, cutting torch or even a come-along.

So, what’s a valve repair and maintenance guy supposed to do?

Switch to the VSG graphite pressure seal from EGC. It’s high-density, Thermafoil® graphite construction means it’s resilient so it seals every time and rebounds after every pressure cycle.

The VSG won’t fuse to valve components ever! It comes out as easy as it goes in so you’ll never again have to use a chisel or re-machine the surface. In fact, you can save nearly 75% installing graphite over metal.

The VSG is compressible and conformable. It can work in oversize, out of round, steam cut and pitted bonnet valves. Try that with a metal seal.

Best of all, the VSG can replace any metal pressure seal. It is custom engineered for each individual application and can be designed, manufactured and shipped in just 48 hours, even faster if you use our FastTrack expedite program.

Switching to the VSG graphite pressure seal is the smart choice that will save you loads of time. Give EGC a chance to make your fall outage the most productive ever! For information on other Power Generation products, call us at 440.285.5835 or visit out website.
