The valve plug has a built-in pilot plug that enables rapid valve operation and allows low valve operation force. The pilot plug uses a simple springless mechanism moved by inlet fluid pressure. It is suitable for high-temperature, high-pressure steam turbines as a bypass control valve, auxiliary steam pressure reducing valve, or blow-off control valve.
