Scope: The BHDT high-pressure valve identified by serial number 1231269 has been certified independently by Risknowlogy to IEC 61508:2010. This certificate verifies that the valve meets the functional safety requirements that apply to a final element used in safety-instrumented functions.

The valve is engineered for tight shutoff duty in high-pressure chemical and petrochemical service. Acting in low-demand mode, it performs one safety function — closing the valve on demand within a defined response time. Valve 1231269 is installed as part of a final element assembly, where it works alongside an actuator, a solenoid, and the associated pneumatic components.

Certification proceeded by compliance route 1H. Under that route, Risknowlogy evaluated the valve's failure modes, failure rates, and architectural constraints against IEC 61508. The valve is a Type A device whose failure behaviour is well defined and predictable, and its design originates from an established BHDT concept with documented operational history.

The assessed failure data, combined with the route taken, establish that valve 1231269 is fit for use in SIL 1 safety functions at HFT = 0 and in SIL 2 safety functions at HFT = 1, in accordance with IEC 61508. It carries its own certificate, number 2628.653.10-1, issued 2026-06-09.

This certification assures end users, EPCs, system integrators, and asset owners that valve 1231269 can be integrated into safety-instrumented functions within a compliant functional safety lifecycle. Validity continues only while the valve design is unchanged and while 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 stays with the end user. The full certification basis, conditions of use, and end-user responsibilities are recorded in certificate 2628.653.10-1 and the supporting Risknowlogy assessment report 2628.653.16.
