    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.
