Scope: Risknowlogy has independently certified BHDT high-pressure valve 1231404 to IEC 61508:2010. The certificate confirms that the valve satisfies the functional safety requirements applicable to a final element in safety-instrumented functions.

Valve 1231404 is made for tight shutoff in high-pressure chemical and petrochemical service. Its safety function, performed in low-demand mode, is to close on demand within a defined response time. The valve forms part of a final element assembly, working together with an actuator, a solenoid, and the associated pneumatic supply components.

Assessment took place under compliance route 1H, with Risknowlogy reviewing the valve's failure modes, failure rates, and architectural constraints against IEC 61508. The valve is a Type A device, a classification denoting well-defined and predictable failure behaviour, and its design is based on an established BHDT concept supported by a documented service record.

On the strength of the assessed failure data and the chosen route, valve 1231404 is fit for SIL 1 safety functions at HFT = 0 and for SIL 2 safety functions at HFT = 1, as set out in IEC 61508. The valve is covered by its own certificate, number 2628.653.13-1, issued 2026-06-09.

This certification gives end users, EPCs, system integrators, and asset owners confidence that valve 1231404 can be built into safety-instrumented functions as part of a compliant functional safety lifecycle. The certificate remains valid 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 is borne by the end user. The detailed certification basis, conditions of use, and end-user responsibilities are defined in certificate 2628.653.13-1 and the supporting Risknowlogy assessment report 2628.653.16.
