Product Description

500X Pressure Sustaining Relief Valve
 

Pressure Relief Valve is an accurate and pilot control valve. It can be relief a high inlet water pressure to keep normal water pressure in main pipeline. 
The pilot valve control and response to the differential pressure produced across an orififice plate which installed downstream of the valve. And there are several orifificeplate with different hole for each size.
