Double Block & Bleed Valves

Built with our unmatched ruggedness, our Double Block & Bleed Valves are available with threaded, weld or flanged inlet/outlet. Designed to replace the typical stack-up found in ad-hoc installations, the PRECISION Process Valve Series simplifies BOMs and installations, reduces leak paths and saves weight, space, and cost.
