White Paper About Safety Compliance for Solenoid Valves

Regulatory modifications have raised important issues in design and use of industrial safety systems. Certain changes in IEC 61508, now being widely implemented, mean that designers and users who desire full compliance must give new consideration to topics such as SIL levels and the transition to new methodologies.

In particular, these issues can impact the selection of solenoid valves and prepackaged redundant control systems (RCS) for implementation in a safety instrumented system (SIS). Such selections may also be affected by how experienced valve suppliers are at dealing with complex new compliance methodologies.

These issues are especially applicable to the oil, gas, chemical, and power industries - in applications such as safety shutdown systems, boilers, furnaces, high-integrity protection systems (HIPS), and more. These issues are of concern to safety engineers and reliability engineers, as well as to process engineers, engineering executives, and plant managers.

This report, a white paper made available by ASCO Valve, will address these issues in developing a compliant safety instrumented system using valves and redundant control systems. Making the right choices in safety system planning and in valve supplier selection can affect design time, costs, and effort — as well as the safety of the plant itself.
