VS - Turbine Bypass Isolation / Stop Valve
Reliable turbine bypass stop valve for power plants, ensuring tight shut-off and minimal material stress.
Forged steel body minimises material stress, ensuring durability and reliability in high-temperature applications.
Tight shut-off with ANSI Class V leakage rating eliminates gaskets, providing a secure and maintenance-friendly design.
Compatible with pneumatic, electrohydraulic, or electromechanical actuators for flexible operational control.
The IMI CCI VS Turbine Bypass Stop Valve is engineered for high-performance operation in modern fossil-fuelled power plants. It provides reliable shut-off upstream of high-pressure and low-pressure turbine bypass valves and is also suitable for isolation in process steam lines and spray water systems. Designed for severe service conditions, the valve minimises material stresses and eliminates gaskets to ensure ANSI Class V leakage tightness. The forged CrMo or carbon steel body enhances durability, while multiple actuator compatibility allows flexible operation. A pressure-seal bonnet and corrosion-resistant plug further improve reliability, safety, and ease of maintenance.
