The ASCO 327 is a 3/2-way direct operated (direct acting) solenoid valve with a balanced poppet design, built for pilot applications that demand wide pressure ranges and zero minimum operating pressure. Available in brass or AISI 316L stainless steel bodies with a universal (NC / NO / diverter) function, it delivers reliable on/off control of air, inert gas, water, and oil from 0 to 10 bar. SIL 3 capability (IEC 61508, TÜV & Exida) and a full ATEX/IECEx explosion-proof range make it a proven choice for safety instrumented systems across oil & gas, chemical, and power generation.
Key Features
- Zero minimum operating pressure — starts and operates from 0 bar differential for pilot, vent and drain service
- SIL 3 capability per IEC 61508, TÜV & Exida certified for functional safety / SIS loops
- PTFE rider rings and graphite-filled PTFE seals eliminate friction and sticking for exceptional service life
- ATEX/IECEx explosion-proof range (Ex db, Ex eb mb, Ex mb, Ex ia) plus NEMA 7 & 9; 316L SS for corrosive atmospheres
- Class H insulated coils, DC peak-voltage suppression, low-power options to 0.5 W; NACE-compliant and vibration-resistant
