Double Block and Bleed Valve
Two lines of protection, when you need it most.
The Double Block and Bleed valve contains all the same Guided Shear Gate design features you’ll find in our traditional SSKGVs, however it is fully compliant to MSS-SP-152. This valve is designed to provide bi-directional zero leakage from full vacuum to ASME Class 1500 / PN 250 (3750 psig / 250 barg). DBBs are utilized by customers who need to be absolutely sure isolation has been achieved. They remove the need for multi-valve systems, thus saving cost, time, and space.
