From out-of-round to in-a-jiffy

You’re doing maintenance on a check valve and repairing the seat. So, you’ve removed the bonnet to get to the trim and find the pressure seal cavity is damaged.  Now your work has doubled. But when every minute is money, how do you make sure you’ve got the right dimensions quickly and easily for a new pressure seal that will work?

Replacing a pressure seal is tricky because the seal you removed can’t be replaced with a duplicate. There may have been things that have changed the dimensions of the valve cavity. Maybe there are steam cuts or an out-of-round occurrence because of over-pressurization. Perhaps an ever so slight adjustment in bonnet neck height or the valve bonnet neck OD. Or maybe a previous modification was made to the valve.

So, you start a series of measurements that indicate the exact size of the cavity. And, it makes no difference whether you’re replacing a metal seal with metal or metal with graphite. The dimensions must be checked and written down.

So, this time, you’ve decided to buy a VSG Thermafoil® pressure seal, one that’s made from high-density graphite and comes to you in 48 hours or less. Well, we’ve created an easy way for you to record specific measurements making the whole process a whole lot easier.

It’s called the VSG Data Sheet and it starts with your company contact information and winds up with cavity and seal dimensions. So, you give us complete information and we’ll get you the right product for the job. When you submit it to EGC, you’ll see how easy it is to custom engineer a seal and get it to you exactly when you need it.

What happens if you don’t fill out the required information? There are questions, delays and a whole lot of potential for seal failure.

So just click to see the on-line VSG Data Sheet, the print-and-return VSG Data Sheet, OR watch the three-minute video on how the measurement system works. If you have any questions please give us a call at 440.285.5835.
