Precise differential pressure control
Small volume and light weight
Large flow
Reliable full hydraulic control
Tight and reliable sealing performance in closing
Built-in strainer, to prevent the guide piping system from being blocked
DR300 lightweight pressure differential relief valve is a fully automatic hydraulic control valve, designed to maintain pressure differential between two pipelines, to avoid the pressure differential of pipelines exceeding the range the system can hold due to other valves operation or demand change. The valve will open when the pressure differential increases and will automatically close when the differential pressure decreases.
If the optional check feature is selected, 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: 0.1~2.5 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.
