- Sizes: 3" to 48" (DN80 to DN1200); up to 60" on product page enquiry
- Pressure: ASME Class 150–900 · PN16–PN160
- Actuation: heavy-duty scotch-yoke pneumatic or electro-hydraulic, fail-safe
- Testing: API 598 / ISO 5208, PST online, fire-safe certificate
Key specifications
ROSOV vs ESDV
An ESDV is closed automatically by the plant ESD system. A ROSOV is designed for remote operator shut-off from a safe location (and may also be tied into automatic shutdown). Hardware is often the same: fire-safe TOBV + fail-safe actuator. See the ROSOV guide for HSG244 / IEC 61511 requirements.
What to send with your enquiry
