When Indonesian Engineering Meets Geothermal: NMS Gate Valve Expanding Type Gains Recognition from EBTKE

A step forward in proving that Indonesia can manufacture critical geothermal wellhead equipment

Indonesia has one of the largest geothermal potentials in the world. With geothermal development continuing across the country, the industry needs not only investment and technology, but also stronger domestic capabilities to provide the equipment required for geothermal operations. For PT Nurman Mitra Sentosa (NMS), this is where the journey becomes meaningful. NMS has developed and manufactured a Gate Valve Expanding Type for geothermal well applications in Indonesia—demonstrating that Indonesian engineering and manufacturing capabilities can contribute to the supply of critical equipment for the country’s geothermal industry. A significant moment in this journey came when the NMS Gate Valve was presented and viewed by Dr. Priatin Hadi Wijaya, S.T., M.T., Director of Geothermal at EBTKE, Ministry of Energy and Mineral Resources of the Republic of Indonesia. For NMS, the moment represented more than simply presenting a product. It represented a glimpse of what Indonesian manufacturing can achieve.

From an Idea to a Geothermal Solution

Developing equipment for geothermal wells requires a strong understanding of the operating environment. High temperatures, pressure, demanding well conditions, and the need for reliable wellhead equipment create challenges that require careful engineering and manufacturing. The development of the Gate Valve Expanding Type was part of NMS’ commitment to answering those challenges through domestic capability. Rather than simply becoming a distributor of imported equipment, NMS continues to develop its role as an Indonesian engineering and manufacturing company, working to produce equipment that can be applied directly to the country’s geothermal operations. The Gate Valve Expanding Type is one representation of that effort.

A Moment of Recognition

When the NMS Gate Valve was presented to Dr. Priatin Hadi Wijaya, S.T., M.T., the moment carried a significance beyond the product itself. It provided an opportunity to showcase an Indonesian-manufactured solution designed for the geothermal industry and to demonstrate the capabilities that have been developed locally. For the NMS team, having the product viewed by the Director of Geothermal at EBTKE was an important milestone. It served as a reminder that the development of domestic geothermal equipment is not only about manufacturing a component. It is about building confidence in the ability of Indonesian companies to participate in a technically demanding industry.

Indonesia Can Make It

For decades, many critical oil and gas and geothermal equipment products used in Indonesia have been associated with international manufacturers. But the question is no longer simply whether Indonesia can use advanced geothermal equipment. The more important question is: Can Indonesia manufacture it? NMS believes the answer is yes. The development of the Gate Valve Expanding Type demonstrates that Indonesian companies can take on the challenge of designing, manufacturing, testing, and preparing critical wellhead equipment for geothermal applications. It is a step toward reducing dependence on imported equipment while strengthening the domestic industrial ecosystem. And perhaps most importantly, it creates opportunities for Indonesian engineers, technicians, welders, machinists, inspectors, and manufacturers to contribute directly to the development of the country’s energy resources.

More Than a Gate Valve

At first glance, a Gate Valve may appear to be only one component within a much larger wellhead system. But behind that component is a much bigger story. There are engineers who develop the design. There are machinists who manufacture the components. There are welders and technicians who work to meet stringent requirements. There are quality personnel who inspect and verify every stage. And there is a team that takes responsibility for delivering a product that is expected to perform in one of the most demanding environments in the energy industry. That is the story behind the NMS Gate Valve Expanding Type. It is not only a product. It is a representation of Indonesian capability.

Supporting Indonesia’s Geothermal Future

Indonesia’s geothermal future will require collaboration between government, operators, technology providers, manufacturers, and local industries. Domestic manufacturers have an important role to play in that ecosystem. By developing products such as the Gate Valve Expanding Type, NMS aims to contribute to the growing TKDN and local manufacturing ecosystem, while continuously improving its technical and manufacturing capabilities. The goal is not simply to replace imported products. The goal is to build Indonesian products that can meet the requirements and expectations of the geothermal industry.

A Step, Not the Finish Line

Having the NMS Gate Valve viewed by the Director of Geothermal at EBTKE is an important milestone. But NMS sees it as a beginning rather than an ending. There is still more to develop, more to test, and more to improve. The geothermal industry continues to evolve, and Indonesian manufacturers must evolve with it. NMS is committed to continuing that journey—developing products, strengthening manufacturing capabilities, and supporting Indonesia’s geothermal industry with solutions made by Indonesian hands. Because every successful locally manufactured component tells a bigger story. Indonesia is not only a country with enormous geothermal potential. Indonesia can also be a country capable of manufacturing the equipment needed to unlock that potential. And for PT Nurman Mitra Sentosa, the Gate Valve Expanding Type is one step toward making that vision a reality.
