In addition, Dawopu offers reverse engineering services, including design optimization and engineering modifications. Stellite® weld repair services are also available for various valve components.

4. Main Stop Valve Upgrade

Main stop valve stem erosion is a common issue experienced by many power plants. Dawopu offers alternative upgrade solutions such as the Triplet Type Main Stop Valve Upgrade.

This design greatly reduces wear on the valve stem and skirt, helping minimize maintenance requirements and extend valve service life.

5. Combined Cycle Valve Drop-In Solution

Our Combined Cycle Valve Drop-In Solution integrates multiple turbine valve wear components into a single pre-assembled package.

This approach allows faster replacement during turbine outages and removes repair activities from the critical outage schedule. Each drop-in assembly is thoroughly inspected, repaired, or replaced in our workshop to ensure reliability for the next operating cycle.

Advanced Steam Turbine Sealing Solutions

6. Guardian® Packing

Dawopu offers the patented Guardian® packing ring, an advanced sealing design that maintains positive radial sealing during turbine shutdown, start-up, turning gear operation, and full-load conditions.

Effective radial sealing is essential for maintaining turbine efficiency and reducing steam leakage.

7. Vortex Shedder® Spill Strips

Our patented Vortex Shedder® spill strip uses aerodynamic geometry to reduce steam leakage while improving turbine stage heat-rate performance.

This design enhances efficiency in reaction, impulse, or hybrid steam path configurations.

8. Conventional Packing and Spill Strips

Dawopu is also a leading manufacturer of conventional sealing systems for steam turbines, including:

• Shaft packing

• Gland packing

• Honeycomb seals

• Spring-back seals

• J-strips

• Caulked-in seals

• Diaphragm packing

All components are manufactured in accordance with OEM specifications and tolerance requirements.

9. Custom Seal Installation

Dawopu specializes in supplying both new and refurbished turbine seals tailored to customer requirements. Our patented products, including Guardian® packing rings and Vortex Shedder® spill strips, are professionally installed by Dawopu technical specialists.
