What Netherlocks Safety Systems does
Netherlocks Safety Systems operates as Sofis, a Netherlands-based manufacturer of industrial valve safety solutions headquartered in Alphen Aan Den Rijn. The company was founded in 1993 and is a subsidiary of Halma PLC, a London-listed global safety, environmental, and analysis technology conglomerate. Sofis positions itself as the world's largest interlock manufacturer, with 30+ years of operational experience and a portfolio that includes three legacy interlock brands — Smith, Netherlocks, and Ellis — alongside portable actuators (EasiDrive, Power Wrench), a remote valve operator (FlexiDrive), a valve position indicator (VPI), a key management system, and a silo loading/unloading system (SiLoC).
The company's core technology is mechanical rather than electronic: interlocks physically enforce correct valve operating sequences, preventing the kind of human error in manual valve operations that can cause safety incidents, process upsets, or asset damage. The FlexiDrive remote operator enables manual valves to be actuated from a safe, accessible location without modifying the valve or adding electrical or hydraulic actuation. Together, the product set addresses three core problems in process plants: enforcing safe valve operating procedures, operating manual valves quickly and without physical strain, and operating valves located in inaccessible or hazardous positions. Recent product marketing has also positioned the portfolio for next-generation energy infrastructure applications including hydrogen and carbon capture.
Revenue is generated primarily through hardware sales of interlocks, actuators, and remote operators, supplemented by engineering services for installation, commissioning, plant shutdowns, turnarounds, and asset management programs. Go-to-market is a global enterprise field sales motion — direct sales via phone and email combined with a network of partner companies, agents, and distributors — targeting blue-chip end users in energy, petrochemicals, chemicals, storage and logistics, and engineering and construction (logos include ExxonMobil, Shell, BP, Total, BASF, Dow, Vopak, Linde, EDF, SBM, Fluor, Technip, and Petrobras). Pricing is not publicly disclosed; quotes are obtained via direct contact. A regional entity, Sofis China, supports local presence in Asia.
