Electric Flanged Ball Valves (ASME / DIN / JIS Standards)
As a core configuration in DELCO’s high-performance Vannes à billes électriques portfolio, our electric flanged ball valves are the heavy-duty industrial workhorse for automated pipeline isolation and throttling. Designed in full compliance with international piping codes, our two-piece split-body valves combine robust cast steel (WCB) or stainless steel bodies with high-torque motorized actuators. Engineered to deliver bubble-tight ANSI Class VI shut-off across water, Hydrocarbures, vapeur, and chemical utilities, they offer seamless 1:1 drop-in replacement for existing flanged pipelines.
ASME / ANSI Standard Series
Pression: Class 150 / 300 / 600 | Bride: ASME B16.5 RF
Manufactured strictly to ASME B16.10 face-to-face dimensions. The standard choice for North American, Latin American, Middle Eastern, and global offshore engineering projects.
DIN / EN Standard Series
Pression: PN16 / PN25 / PN40 | Bride: EN 1092-1 Form B
Built to DIN 3202 F1/F4 face-to-face length standards. Perfect for European, Central Asian, and industrial utility plant automation requiring metric flange drillings.
Why Choose DELCO Electric Flanged Ball Valves?
Global standard compatibility, fire-safe certified construction, and heavy-duty electric automation.
API 607 Fire-Safe & Anti-Static Design
Certified to API 607 / API 6FA fire-safe standards with secondary metal-to-metal seating to prevent fuel leakage during fire exposure. Conductive grounding springs ensure continuous static dissipation from ball to stem.
Exact 1:1 Face-to-Face Replacement
Machined in strict accordance with ASME B16.10, DIN 3202, and JIS B2002 face-to-face dimensions. Guarantees seamless drop-in retrofit for existing pipeline valves without cutting, pipe shifting, or re-welding.
Blow-Out Proof Stem & Faibles émissions
Internally assembled blow-out proof stems prevent stem ejection under internal line pressure. Multi-layer V-ring PTFE/Graphite stem packings eliminate fugitive volatile emissions in compliance with ISO 15848-1 environmental laws.
Floating & Trunnion Sizing Optimization
We supply floating ball designs (DN15–DN150) for cost-effective Class VI shut-off and trunnion-mounted designs (DN200+) to dramatically reduce operating torque, saving up to 40% on electric actuator motor sizing costs.
ISO 5211 Direct-Mount Bracketless Pad
Integrated ISO 5211 direct mounting top flanges eliminate external brackets and couplings. This rigid assembly prevents rotational backlash, Réduit la perte de couple de transmission, and ensures long stem packing lifespan.
100% Factory Pressure Tested (API 598)
Every complete automated valve assembly undergoes 100% shell hydrostatic pressure testing (1.5x PN) and bidirectional seat leak testing (1.1x PN / pneumatic) per API 598 / ISO 5208 standards before export packing.

Questions fréquemment posées (FAQ)
Q1: How do I ensure your flanged ball valve matches our existing pipeline dimensions?
DELCO flanged ball valves are machined strictly to standardized international face-to-face lengths: ASME B16.10 for ANSI Class 150/300/600 valves, and DIN 3202 (F1 or F4 series) for European EN 1092-1 PN16/40 valves. Simply provide your current valve standard or face-to-face measurement during quoting, and our engineers will guarantee an exact 1:1 drop-in replacement without piping modifications.
Q2: What is the difference between Floating Ball and Trunnion Mounted Flanged Ball Valves?
In floating ball valves (standard for DN15–DN150), line fluid pressure pushes the ball downstream against the soft seat to achieve tight Class VI sealing. In trunnion-mounted valves (recommended for DN200+ or Class 600+), the ball is mechanically anchored by top and bottom bearings, and spring-loaded seats seal against the ball. Trunnion mounting dramatically reduces operating torque, enabling the use of smaller, more economical electric actuators on large lines.
Q3: Are DELCO electric flanged ball valves certified for fire-safe service?
Oui. Our flanged ball valves can be supplied with certified API 607 / API 6FA fire-safe compliance. In the event of a plant fire that incinerates the primary soft PTFE seat, an engineered secondary metal-to-metal seat automatically engages with the ball, preventing destructive fuel leakage. In addition, our electric actuators offer certified ATEX / IECEx Ex d explosion-proof enclosures for hazardous refinery zones.
Q4: What material certificates and inspection test reports are provided?
All valves undergo 100% shell hydrostatic testing and pneumatic seat leak testing per API 598 / ISO 5208 standards, accompagné d’un certificat de conformité standard (COC). For engineering projects, traceable EN 10204 3.1 Material Test Reports (MTR) for pressure-containing bodies and trim, third-party inspection (TPI), and formal hydrostatic test records are readily provided upon request based on your project specifications.
