ADAMS Valve Replacement in District Heating System

1. Project Background

The client is a power plant upgrade project in Inner Mongolia, involving a heating system expansion EPC project.

The system originally used a DN1400 PN25 electro-hydraulic fast-opening butterfly valve from ADAMS, operating at approximately 380°C.

2. Challenges

• Large-size valve with fast-opening requirements

• High temperature and dynamic operation

• Reliability requirements in heating system

3. Our Solution

Procetek provided a customized solution:

• Large-diameter Penta-offset butterfly valve
