VLB Steam Conditioning Valve
Efficient steam conditioning valve with pressure and temperature control for turbine bypass systems.
Precise steam regulation ensures reliable turbine bypass operation.
Reduces thermal stress, extending valve lifespan and efficiency.
Customisable connections adapt to specific steam line needs.
The IMI CCI VLB Steam Conditioning Valve is an angle-style valve designed to regulate both pressure and temperature in high and low-pressure turbine bypass systems. It is commonly used in power plants and process industries where precise steam control is essential. The VLB valve features multiple pressure-reducing stages, along with a desuperheating stage for temperature control via spray water injection. The fully machined forged body reduces thermal stress and improves thermal cycling, while the hard-faced seat ensures durability and low maintenance. With customisable inlet and outlet connections, this valve offers reliable performance under extreme conditions.
