Product Desciption
1.Products details
Name:Pressure sustaining relief DN90 hydraulic control valve
01.Description
Pressure relief/pressure holding valve is composed of hydraulic control valve main valve and pressure relief guide valve. It is a commonly used pressure control valve to control the opening and closing of main valve through the opening and closing of guide valve.The valve is suitable for the water supply network or building water supply system to relieve pressure, so that the system pressure is not higher than the valve set pressure value, to ensure the safety of the system pipeline or to maintain the minimum water supply pressure of the pipeline in front of the valve.
02.Main parts&material
03.Features
001.Hydraulic control, no external driving force.
002.The main valve has only one moving part and the failure rate is low.
003.Diaphragm structure, no friction, high control sensitivity.
004.The pressure behind the valve does not change with the change of the pressure in front of the valve.
005.The pressure behind the valve does not change with the change of system flow;
006.Good static pressure reduction effect;
007.Wide range of pressure regulation after valve;
04.Dimensions
05.Execution standard
06.Technical parameters
07.Operating principle
The relief/holding valve is composed of the hydraulic control valve main valve and relief guide valve, controlling the opening and closing of the main valve through the opening and closing of the guide valve.
The relief guide valve is connected to the front end of the main valve through a copper pipe to sense the pressure in the front end.When the pressure at the front end is greater than the set pressure value of the valve, the pressure relief guide valve is opened and the upper chamber of the main valve is drained outward to open the pressure relief valve.When the pressure at the front end is less than the set pressure value of the valve, the pressure relief guide valve will be closed and the upper chamber of the main valve will stop draining water to the outside, so that the main valve will gradually close and achieve zero leakage.The valve setting pressure value can be adjusted through the adjusting screw on the relief guide valve.
