Solenoid Valves for Valve Automation: Selection, NAMUR and Hazardous-Area Guide
The solenoid valve is the electrical-to-pneumatic link that makes an actuated valve stroke. This guide covers direct-acting vs pilot-operated designs, 3-way and 5-way functions, NAMUR mounting, and hazardous-area certification.
Valve Antistatic Devices and Hazardous Area Selection Guide
In quarter-turn valves the ball or plug is electrically insulated from the body by non-conductive seats, so operating the valve can build a static charge. An antistatic device provides a conductive path to earth, preventing a spark in flammable service. This guide explains the design and hazardous-area requirements.
Fire-Safe Ball Valves: API 607 Testing, Metal Seat Secondary Seal & ATEX Certification
A fire-safe valve must maintain acceptable external leakage rates even after all polymeric seats, seals, and packing have been burned away in a 750°C–1000°C flame for 30 minutes. This guide covers API 607 fire test requirements, the burn-out test protocol, metal seat secondary seal design, graphite packing backup, and ATEX/IECEx certification requirements for hazardous area valve actuators.
