Steam conditioning valve
The VLB is an angle-style steam conditioning valve, used for turbine bypass or process control. It is designed to reduce the pressure and temperature of the steam to match the downstream requirements. The valve features a series of pressure reducing stages, designed specifically for each application to minimise noise. Regulation of the pressure is performed with a modulating plug, revealing a series of perforations in the valve bonnet cage as the valve opens. Temperature regulation is controlled by an external spray water control valve. Spray water injection takes place in the valve outlet, using a series of mechanical atomising nozzles.
