500X pressure discharge/sustain valve uses a pipeline system to prevent it from surpassing pressure of keep the pressure of it, to reduce the water hammer¡¯s shock after the pump is closed and also used as a water hammer remover for a large water supply system. On the inlet of the valve¡¯s control system a self cleaning filter screen is placed, which, by means of the bigger specific gravity of the fluid, stops the suspension grains of a bigger specific gravity and diameter going into the system to ensure the main valve¡¯s water supply pressure at the upstream at a set value to get the system smoothly circulated without any resistance. This valve features sensitive open-close, safety, reliability, stable motion and long duration.
