Research & Development

From product design to customer requirements, ZECO Valve Group is composed of valve expert team with profound industry and product knowledge, using the most advanced 3D design software, from concept to detailed design and verification, to production details. The design verification process includes finite element analysis of stress, deflection, thermal effect and flow and computational fluid dynamics simulation. ZECO Valve uses front-end design and development tools to develop and improve product designs to ensure that products consistently meet the highest international standards. 

Focusing on safety, low maintenance, long service life and high quality, ZECO valve China designs each product series and optimizes all production details to provide competitive prices. ZECO's design team can ensure the fastest response to meet the requirements of customers around the world. The r&d team is an important part of the engineering team of ZECO.

The services we provide include technical project management, design and analysis, standard and customized experimental work, performance evaluation, and technical support from project start-up to project completion. Worldwide, ZECO valves are the preferred valve supplier of valve automation solutions for low temperature, low emission, large size and high pressure international standard valves.
