Seals in all sizes. And engineering expertise to match.

When Rob Garlock, our lead pressure seal design engineer, looked at the valve print he couldn’t believe his eyes.  This wasn’t anything close to a typical pressure seal, which usually measures somewhere between 4 to 24 inches. This pressure seal was 45 inches in...

Out of Round? No Problem!

A valve was over-pressurized in a west coast nuclear power plant.  It led to an extreme condition called out-of-round in the pressure seal cavity.  They called the manufacturer but there was no way to machine the cavity back to accepting a metal seal. And, it would...
