China Jingjia Valve (Group) Co.

SJ500X Pressure Relief

This valve is mainly used in pipeline systems to prevent overpressure in the pipeline system or maintain the pressure of the pipeline, and can also reduce the impact of water hammer when the pump is turned off. It can also be used for the water hammer elimination device of large water supply systems, and a self-cleaning filter screen is installed at the inlet of the valve control system, using the characteristics of the fluid, so that the suspended particles with larger specific gravity and larger diameter will not enter the control system, ensuring the main control system. The upstream water supply pressure of the valve can make the system circulate unobstructed at a certain set value.

Use in a pipeline system to prevent it from surpassing pressure or keep the pressure of it. to reduce the water hammer's shock after the pump is closed and also 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 sys-tern 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.
