EGVT Steam Turbine Bypass Control Valve
The EGVT steam turbine bypass control valve is a low-noise control valve for high-pressure steam. Its internal components consist of a porous sleeve-guided pilot valve core. It achieves rapid action of the valve core relying on fluid pressure instead of a spring, thus requiring small operating force. This control valve is suitable for regulating high-pressure steam in the high-pressure bypass of steam turbines and controlling pressure reduction of auxiliary steam.
