The 60P00 Series high pressure bypass control valve

The 60P00 Series high pressure bypass control valve is a high differential pressure control valve with special structures. The control valve has the function of starting the control valve, pressure reducing bypass valve and safety valve. It can realize fast automatic tracking and over-pressure protection, and the boiler safety valve is saved.

The valve can realize fast starting within 6 seconds. Through adjusting the steam pressure, the control system of the electric actuator can be suited to parameter starting, stopping and running of the unit under different service conditions. After load shedding by the unit, the boiler may not stop immediately and can start running again within several minutes after the malfunction is eliminated. Thus, not only the starting and stopping times of the boiler are reduced, but heat impact on the turbine is reduced. The adjustment of desuperheater water is quickly linked to the high pressure bypass, so that temperature and pressure are lowered to a great extent, and the bulky temperature and pressure reducing systems and equipment in power plants are reduced. Therefore, the valve is an important control valve in reheating unit bypass systems of large volume units.
