Series DB5500 Double Block and Bleed Plug Valve

DB5500 Double Block and Bleed Plug Valve (DBBV) dual expanding Plug Valve and non friction Double Tight shut-off valve in both the up and down stream.

Description

DB5500 Double Block and Bleed Plug Valve (DBBV) dual expanding Plug Valve and non friction Double Tight shut-off valve in both the up and down stream.  No Maintenance and the valve reduces space.  The DB5500 series has two seated surfaces (slips). When the valve is in closed position each individual seal is fully isolating, not allowing any leakage from downstream, upstream nor from the body cavity. A thermal relief vents / bleeds the body cavity when overpressure occurs so the downstream pipeline is fully isolated from upstream pressure without there being pressure balancing necessary.
