Issued and certified by Risknowlogy — independent certification body for functional safety, operating according to IEC 61508 and IEC 61511.
Scope: BHDT high-pressure valve 1231355 is the subject of an independent functional safety certificate granted by Risknowlogy under IEC 61508:2010. The certificate confirms that the valve meets the applicable functional safety requirements for service as a final element in safety-instrumented functions.
Operating in low-demand mode, valve 1231355 carries out a single safety function: it closes on demand within a defined response time. The valve is intended for tight shutoff in high-pressure chemical and petrochemical processes and is installed within a final element assembly that brings together the valve, an actuator, a solenoid, and the related pneumatic components.
The certification rests on compliance route 1H. Following that route, Risknowlogy evaluated the valve's failure modes, failure rates, and architectural constraints against the provisions of IEC 61508. Valve 1231355 is a Type A device — its failure behaviour is well defined and predictable — and its design is derived from an established BHDT concept with a documented operating history.
Drawing on the assessed failure data and the applied compliance route, valve 1231355 is fit for SIL 1 safety functions at HFT = 0 and for SIL 2 safety functions at HFT = 1, in accordance with IEC 61508. The valve holds individual certificate 2628.653.12-1, issued 2026-06-09.
For end users, EPCs, system integrators, and asset owners, this certification confirms that valve 1231355 can be integrated into safety-instrumented functions as part of a compliant functional safety lifecycle. The certification stays valid only where the valve design is unchanged and where the end user applies, installs, operates, and maintains it correctly. Responsibility for safe integration into the overall safety-instrumented system, for proof testing, and for lifecycle management under IEC 61508 falls to the end user. The full certification basis, conditions of use, and end-user responsibilities are defined in certificate 2628.653.12-1 and the supporting Risknowlogy assessment report 2628.653.16.
