Through Conduit Gate Valves

Features
STARTEK Cast Steel Through conduit Gate Valves have been designed to meet the requirements of API 6A
Face to Face and End to End dimensions conform to API 6A
End flange dimensions conform to API 6A
Butt weld end dimensions conform to API 6A
Screwed end dimensions conform to API 6A
