TrunTech®

2-36"

150-2500#

Eraway's’ TrunTech® is designed to address the severe service demands of the upstream and midstream oil and gas industries. Its protected seat seals design provides long life and tight shut-off in abrasive / erosive conditions and meets stringent fugitive emission requirements. TrunTech® is designed to API-6D and API-6A, fire-safe per API-607 (API-6D) and API-6FA (API-6A), tight-shut-off per ISO-5208 Rate A (API-6D) and PSL-3 (API-6A).

- Carbide sealing surfaces. The sealing surfaces are overlaid with tungsten or chromium carbide using the Eraway's-exclusive HVOF RiTech® coating process. These surfaces have a hardness of 68 – 72 Rc to allow long periods of operation in the most severe conditions.
- High integrity seals. To prevent leaks around the seats, Eraway's has developed an innovative double seal design for erosive services operation in high cycling applications. A secondary graphite seal is installed toward the body cavity.
- Solids resistance. In addition to the carbide coatings which will allow the valve to function in highly abrasive applications, the individual valve parts have additional seals to prevent interference from solids in the system. This provides for outstanding service in severe-service isolation applications with high particle content from sand, elemental sulfur, hydrate, perforation shrapnel and pipe corrosion products.
