Description
The Fisher Digital Isolation DSV1000 is a three-piece, trunnion-mounted, full-bore ball valve engineered for isolation service in Safety Instrumented System (SIS) applications, designed to provide little or no restriction to flow.
Key Features
•Designed as a complete valve solution: engineered, built, and tested as a full assembly.
•Factory documentation kept complete: serial card, assembly “birth certificate”, and assembly hookups (traceable paperwork).
•SIL support available: SIL verification & certification services.
•Single point of contact for quote, order, and support—practical for traders & procurement.
•Digital valve assembly concept under the Digital Isolation solution set.

Selection Guide
To quote correctly, please confirm:
•Size (NPS), Pressure Class (150/300/600), and End connection requirement
•Actuation: pneumatic / electric / hydraulic / manual, plus fail action if any
•Seat & trim preference (standard vs. service-specific), and temperature range
•Process media & service (isolation, ESD, on/off frequency), and any NACE requirement
•Required documents: datasheet, CoC, MTC/CMTR, serial traceability, etc.
Applications
•SIS / ESD isolation duties where a full-bore, low-restriction path is preferred
•Oil & gas / chemical / upstream & midstream packages needing traceable isolation valve assemblies
Project Support
We can support traders and buyers with:
•Cross-reference & exact configuration check (avoid wrong trim/actuation)
•Documentation package coordination (CoC/MTC/serial traceability where applicable)
•Packing & shipping support: export packing, marking, and consolidated shipment if you bundle items
