Machine Shop Dept: Valve Repairs
Client: Aqualia Mace
Project: STW Al Dhakhira

This project involved the refurbishment of a DN 250 non-return valve (NRV) used in sewage treatment infrastructure. The scope included dismantling, inspection, machining of internal components, replacement of seals, and corrosion protection. The valve was restored to ensure reliable one-directional flow and prevent backflow within the system. Pressure testing and functional checks were conducted to verify operational integrity. The refurbishment improved system reliability and reduced the need for costly valve replacement while meeting operational and safety requirements.
