Product Overview
The S-LOK SDB1FA-14BBN-R12BBN-S6-TE is a precision-engineered instrumentation double block and bleed (DBB) valve designed for critical isolation, venting, and verification duties in high-purity and high-pressure process systems. Manufactured by S-LOK, a recognized name in instrumentation-grade fluid control components, this valve integrates two independent isolation paths and a single bleed/vent port within a single compact body, eliminating the need for multiple discrete valves and reducing potential leak points. The working principle relies on a dual ball or needle-style isolation mechanism that permits primary and secondary block functions, while the integrated bleed port allows controlled venting of trapped fluid between the two isolation seats. This configuration is essential for safe maintenance, instrument calibration, and positive isolation in hydraulic, pneumatic, and process instrumentation circuits.
