Sub-Sea Valve Engineering Subsea Valve Engineering and Manufacturing are critical disciplines in the valve industry. It is not an area for high volume commodity manufacturing. It is the domain of the valve artisan. To excel, it is necessary to consider design functionality, available technology, manufacturing processes as well as environmental and cost impact. Newmans Sub-Sea division is not a mass production operation. Every completed product is truly that, completed in every sense and to the client’s exacting specification. We listen to your requirements as these differ with every client. Newmans works with you to achieve the best possible outcome for your service. In short, you get what you want. We specialize in short to medium term delivery requirements at competitive market rates.
