VLB Steam Conditioning Valve
The VLB is an angle-style steam conditioning valve, used for high/low pressure turbine bypass or as a process valve. It regulates both steam pressure and temperature, reducing it from a higher-pressure system to match the requirements of a lower-pressure system. The valve is equipped with multiple pressure reducing stages and an integrated desuperheating stage at the outlet to ensure optimal performance.
Key features
- Multi-stage pressure reduction for controlled flow and noise abatement.
- Integrated spray water injection for efficient desuperheating at the outlet.
- Homogeneous forged valve body to minimise thermal stress.
- Customisable inlet and outlet connections to fit customer steam pipes.
- Balanced tight design available to reduce required opening forces.
