LTB Low Pressure, Low Temperature Turbine Bypass Valve
Angle body bypass valve for steam conditioning and pressure control in power and industrial applications.
Efficient pressure control with multi-stage pressure reduction for optimised steam conditioning.
Low maintenance design with a quick-change seat and reliable balanced trim.
Reduced operational noise through engineered flow paths and perforated cage technology.
The LTB is a steam conditioning valve used to simultaneously reduce steam pressure and temperature to meet downstream requirements in turbine bypass systems or process control. Available in both angle and globe design, it features a perforated cage for staged pressure reduction, a balanced trim to minimise actuation force, and spring-loaded nozzles for effective steam atomisation. A quick-change seat allows for simple maintenance, while the extended outlet ensures optimised steam flow. Built for high temperatures and low noise operation, the LTB meets strict leakage standards and supports various actuator options, providing reliability and efficiency in demanding environments such as power generation, combined cycle plants, and industrial steam systems.
