OEM service in industrial valve manufacturing is not only about putting a customer's name on a product. It is about translating specific project requirements into a valve solution that matches technical standards, working conditions and market expectations.
At Demelong, we support OEM cooperation for different plug valve types, including sleeved plug valves, inverted lubricated plug valves, lifting metal seated plug valves, eccentric plug valves and double block and bleed plug valves.
What We Offer
We support OEM projects that require design adjustment based on the customer's market, application or technical standard. Some customers need standard valves with brand customization. Others need structural modifications for special service conditions. We work on both directions.
Different industries require different material solutions. Media composition, corrosion risk, temperature, pressure and maintenance expectations all affect the right valve material choice. For OEM projects, material flexibility is often one of the most important parts of cooperation.
Not every market needs the same valve performance. Some customers focus on shut-off reliability. Some need lower torque. Some need better resistance to demanding media. Others need double isolation or actuator-ready configurations.
Our OEM service is built on an existing product platform rather than on a single model. The current site shows coverage across several major plug valve categories, which gives us a strong base for project-specific cooperation.
OEM valve projects require clear technical communication before production. Even small differences in dimension, end connection, material or operating requirement can change the final product result.
