As an irrigation valve, the hydraulic irrigation valve is actually similar to the pressure reducing valve. The pressure reducing valve for irrigation system mainly protects against the phenomenon of water hammer in the pipeline. It is generally installed at the beginning of the pipeline to control the water pressure of the pipeline to prevent the problem of water hammer. Commonly used drip irrigation system drip irrigation flow control valve structures are spring type, lever type and open type. How to choose depends on the pipeline water pressure range and size. <br> <br>Manual Control Valve <br>Installed with main valve and 3-way drip control valve to be open/close controlling valve, easy to operate. <br> <br>Size: 2&quot; (Dn50), 3 (Dn80), 4&quot; (Dn100). <br>Connection: Threaded / Flange. <br> <br>Control Valve With Plus Solenoid Valve <br>Installed with main valve and solenoid to be open/ close controlling valve, distance operation by electrical signal. <br> <br>Size: 2”(Dn50), 3”(Dn80), 4&quot; (Dn100) <br>Electric Voltage: 24VAC(DC)/ 12VDC Latching <br>Valve Type: NC (Normally Closed) / NO (Normally Open), with 3 position 2 way <br>Connection: Threaded / Flange. <br> <br>Pressure Sustaining Valve: <br>Installed with main valve, pilot and 3-way control valve to be pressure sustaining system. Remaining the ablove filter system to have enough pressure to flush when the filter system is in self-cleaning. <br> <br>Size: 2”(Dn50), 3”(Dn80), 4”(Dn100). <br>Pressure Adjusting Range: 0.8-6.5bar (11-95psi). <br>Connection: Threaded / Flange. <br> <br>Pressure relief valve for irrigation system <br>Install with main valve, pressure relief pilot and 3-way control valve to be pressure relief system. Fixed after pump set or pressure reducing valve, and open immediately release the pressure when pressure in system is too high. <br> <br>Size: 2”(Dn50), 3&quot; (Dn80), 4&quot; (Dn100)， <br>Pressure Adjusting Range: 1.0-10bar (15-155ps). <br>Connection:Threaded / Flange <br> <br>Level Control Valve <br>Installed with main valve, float and 3-way control valve to be level controlling system. This valve can adjust the level of water pool in same location automatically although the flowing is changed constantly. <br> <br>Size: 2” (Dn50), 3”(Dn80)，4”(Dn100). <br>Connection: Threaded / Flange <br> <br>For more information about drip irrigation control valve and drip irrigation adapter, please feel free to contact us! <br> <br>There are many irrigation system manufacturers, but we are one of the best choices for you. <br>#pressure#reducing#valve#for#irrigation#system <br>[a]https%3A%2F%2Fwww.irrigationhoses.com%2Fproducts%2Fhydraulic-control-valve%2F[/a]
