DN40/50 type GA49H-16C impulse safety valve, also known as the lever type safety valve is mainly used for power plant boiler or steam pressure pipe, impulse safety valve can be used or used separately. When the medium pressure vessel exceeds the allowable value, the valve opening pressure out of steam, when the pressure drops to a certain value when the valve by the lever hammer valve will close quickly to ensure the safe operation of equipment.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
The safety valve device suitable for steam pipeline working temperature are less than 425, the main safety valve and impulse safety valve should be supporting the use of the main safety valve opens to impulse safety valve opening pressure signal, then the whole amount of emissions; when the pressure dropped to the specified value, the main valve is automatically closed, it is necessary equipment for temperature and pressure reduction the widespread use of modern engineering energy saving device in. Widely used in cogeneration, textile, petrochemical, sugar and other industries, to ensure the safe operation of equipment.
