Steel Through Conduit - API 6A
- Our Features
- 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
- Collapsing movement of split gate away from seat during opening eliminates erosion and abrasion of seats and gate
- Weather proof operating system
- Easy maintenance with valve in-line
- Through conduit piggable passage
- Anti-frictional Ball bearings
- Inside screw and yoke construction
- Bi-directional shut-off
- Sealant injector fittings
- Body ports are streamlined, permitting unobstructed flow, reduces turbulence, results in lower pressure drop and lower erosion
- Available in all popular bore sizes and PSL
