3 in-depth engineering guides on SIL — specification, selection, testing and procurement.
Everything on SIL
Vajra's engineering team has published 3 technical guides covering SIL for industrial valve selection, specification, testing and procurement. Browse the full set below.
HIPPS Valves: High Integrity Pressure Protection System Design and Selection
A High Integrity Pressure Protection System replaces or supplements relief valves by closing off the source of overpressure before a rupture can occur. This guide covers the final-element valve requirements that make a HIPPS certifiable.
Emergency Shutdown (ESD / SDV) Valve Guide: SIL, Partial Stroke & Fail-Safe
Emergency shutdown valves are the final element of a safety instrumented function - they must close on demand, every time, even on fire or power loss. This guide covers fail-safe design, SIL, partial-stroke testing, and selection for ESD service.
Industrial Valve Actuators: Pneumatic, Electric and Hydraulic Selection Guide
Selecting the right actuator type for an automated valve is as critical as selecting the valve itself. Pneumatic, electric, and hydraulic actuators each have distinct characteristics, advantages, and limitations that make them suitable for different process environments and control requirements.
