Product: ASCO Solenoid Valves – Manual Reset Pilot Valves.
Product: ASCO Solenoid Valves – Manual Reset Pilot Valves.
The ASCO NVR Manual Reset Valve moves to its fail-safe position when de-energized. The valve in the “up” (latched) position will supply the fluid media or vent the fluid media depending on the piping of the installation, then switch when tripped into the “down” (unlatched) position. The valve is intended to be part of final element subsystem as defined per IEC 61508 and the achieved SIL level of the designed function must be verified by the designer.
The product has met manufacturer design process requirements of Safety Integrity Level (SIL) 3. These are intended to achieve sufficient integrity against systematic errors of design by the manufacturer. A Safety Instrumented Function (SIF) designed with this product must not be used at a SIL level higher than the statement without “prior use” justification by end user or diverse technology redundancy in the design.
