Working in steam under 420 centigrade, the main valve and impulse valve should used
coordinately. The impulse valve starts first to send pressure signal to main safety valve,
which opens and discharges pressure.In the event of the pressure inside the equipment and
conduit surpassing allowable value, the valve automatically opens, which is followed by
full discharge. While the pressure drops to normal parameters, the valve automatically
closes to ensure safe operation of equipment and conduit. |
