Product Overview
The HANSUN SDB1FA-1488N-R1288N-S6-TE-VT-FS-UD-S1 is a high-integrity double block and bleed (DBB) valve assembly engineered for critical isolation service in hydraulic and process systems. Manufactured by HANSUN, this valve combines two independent isolation paths with an integral bleed/vent port in a single compact body, allowing operators to verify zero leakage and safely depressurize the cavity between the two sealing elements. The dual-block configuration eliminates the need for multiple discrete valves, reducing potential leak paths, installation footprint, and maintenance downtime. It serves as a primary isolation and verification device in hydraulic power units, process skids, and pneumatic control circuits where positive shut-off and pressure confirmation are mandatory.

Engineering Features & Advantages
- Precision Performance: Dual independent isolation seats provide redundant shut-off, while the integral bleed port enables positive verification of seat integrity and safe cavity depressurization before maintenance.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust body construction and seat materials selected for hydraulic and pneumatic media compatibility.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement without piping or manifold modification.
- Reduced Leak Paths: Consolidating two block valves and a bleed valve into a single body minimizes external connections and potential fugitive emission points.
- Simplified Maintenance: In-line serviceability and cavity venting reduce system downtime and improve technician safety during isolation procedures.
Typical Industrial Applications
This HANSUN double block and bleed valve is suited for hydraulic power units and process skids requiring verified isolation, plastic injection molding machines and metallurgical presses where safe depressurization is critical, construction and marine hydraulic systems with high-integrity shut-off demands, and CNC machine tools or pneumatic control panels where positive isolation and pressure verification are essential for operational safety.
