G7 Fabricated Gate Valve
All full-penetration, pressure-containing welds on the G7 valve fabricated body have been enhanced to accommodate volumetric and surface examination to confirm the integrity of the valve body under ASME codes.
The blowout-proof stem forms an API Spec 6D-compliant metal-to-metal seal with the bonnet when the stem is in the up position. The backseat isolates and protects the SLS spring-loaded lip seal from line pressure, greatly extending its service life.
