Water pressure relief valve RS500

DINfor pipelinesregulating

Precise pressure control Optional check feature Fast opening, to guarantee pipeline pressure Non-slam design, to prevent fluid impact Excellent and reliable sealing performance Built-in strainer, to prevent the piping system from blocking RS500 pressure relief valve/pressure holding/back pressure valve is a fluid controlled valve. It can maintain pressure of the upstream pipe by regulating the diaphragm of the pressure regulator. The valve can be used in pressure relief, pressure holding and back pressure impact occasions. During operation, the valve senses inlet pressure of the valve by the pressure regulator to control the valve to open or to close. When inlet pressure exceeds the set value, the valve will open quickly to maintain pressure in the pipelines. After pressure release, the valve will close slowly to prevent water hammer impact. If the optional check feature is selected, when the back pressure is generated, the return fluid will enter the air chamber to close the valve to prevent the fluid from back flow. Pressure Regulator Parameters Pressure Regulating Range: 0.1~5 kgf/cm², 2~9 kgf/cm², 7~17 kgf/cm² Please Provide the Following Data When Ordering Valve figure number/size/pressure grade/connecting end type/pressure regulating range/other optional accessories Note: In valve installation, it is strongly suggested that sufficient space should be left for easy maintenance in the future. A strainer shall be mounted in front of the valve to prevent foreign matters from blocking the valve.
