Trunnion Ball Valve Top Entry Bolted Body

Special valve constructions to allow easy on-site maintenance and disassembly with quick access to ball and seats for inspection and repair.

ERREESSE Top Entry valves are suitable for compression and re-injection systems, transmission pipelines, metering skids, Pig-launchers and receiving stations, Off- Shore and On-Shore platforms, gas storage and separations systems suitable for a wide range of high risk industry applications from severe abrasive and slurry to high temperature and cryogenic services, from subsea and LNG plants to topside installations. ERREESSE Top Entry valves can be welded directly onto the pipeline or to the manifold.
