Description

Through Conduit (T.C.) slab gate valve with full bore port, rising stem OS&Y design, and floating seats and gate that are pressure energised for bubble-tight shut-off upstream and downstream under both low and high differential pressure. Features double block and bleed capability and automatic relief of excess body cavity pressure. The smooth, continuous bore allows passage of pigs and scrapers without damage.
