Our team of skilled engineers handles the installation and commissioning of valve interlocks with precision and expertise. Our thorough installation process includes careful planning, installation, and comprehensive testing to ensure everything functions perfectly. We ensure your equipment is installed, commissioned, and handed over efficiently, minimizing downtime and ensuring seamless integration into your operations. By adhering to industry best practices and safety standards, we guarantee that your valve interlocks will perform reliably and effectively from day one.

Detailed ‘topwork’ dimensions guarantee a perfect fit and prevent delays caused by incomplete or incorrect information. Incorrect measurements, last-minute changes in valve type, or the addition of a gearbox can result in the interlock not fitting the valve. If the existing mounting kit cannot be adjusted to match the new valve’s dimensions, a new kit must be urgently procured. This requires collecting the new valve’s topwork measurements and promptly communicating them to the interlock manufacturer for immediate production.

Our service engineers are directly available for any technical assistance, getting your systems back up and running, with the shortest possible delay. Our services ensure minimal downtime and swift resolution of critical issues. Rapid response times reduce potential operational disruptions and prevent extended losses. Our engineers can quickly diagnose and fix problems, ensuring safety and compliance with industry standards.

For one of its customers’s projects, Sofis was asked supply installation support, initially for measuring, installing and commissioning more than 1500 Netherlocks interlocks. In the end, Sofis supplied 1610 Netherlocks interlocks and 8 Smith interlocks. For 99%, the interlocks were installed on pressure relief valves (PSV). The entire process was managed and led by a Senior Service Engineer of Sofis.  construction contract for the refinery to a joint venture of four contractors.

Sofis was invited to perform an interlock survey on Nostrums’ plant facilities. During this survey, Sofis engineers discovered a variety of malfunctions and safety breaches on the interlock systems they came across, mainly caused by the way that the interlocks were operated, changing conditions in the field, and due to lack of maintenance.

Construction teams that lack appropriate experience with handling large interlock installation jobs often waste time and money and encounter common, critical technical issues, resulting in complete valve systems not being operable. Proper understanding of the scope of the installation job therefore saves valuable time.
