China Double block and bleed ball valve manufacturer,factory and supplier,Double block and bleed ball valve 2500LB F304 F316 has two types, trunion mounted and floating, with double insolation and discharge functions.Double block and bleed ball valve 2500LB F304 F316 has two balls, and one discharge valve (needle valve) in the middle. DBB ball Valve could be designed with soft seat or metal-to-metal seat. The sealing is reliable and suitable for the Harsh working conditions.

Double Block and Bleed Ball Valve 2500LB F304 F316 replace existing traditional techniques employed by pipeline engineers to generate a double block and bleed configuration in the pipeline. Two block valves and a bleed valve are as a unit, or manifold, to be installed for positive isolation. Used for critical process service, DBB valves are for high pressure systems or toxic/hazardous fluid processes. Applications that use DBB valves include instrument drain, chemical injection connection, chemical seal isolation, and gauge isolation. DBB valves do the work of three separate valves (2 isolations and 1 drain) and require less space and have less weight.


Double block and bleed ball valve 2500LB F304 F316  is that a valve owns two balls. It could be opened and closed together or separately. The valve could be replaced with the multiple valves in traditional pipelines. Meanwhile, it reduce leakage point in pipeline system, with fast discharge and shutdown function. DBB ball valves can save installation space and reduce pressure of pipeline system. It also owns simplify installation procedure and reduces the cost of maintenance. At present, DBB ball valves made by ANIEC have been used by some end users such as Petronas.
