Product Name: Air Vacuum Relief Valve for Irrigation System Model NO.: Air release valve Type: Self-Operated Material: Nylon Power: Solenoid Connection Mode: External Thread Standard: Standard Media: Water Temperature: Ordinary Temperature Male Thread: Bsp / NPT Trademark: Chinadrip Transport Package: Export Cartons Specification: 1/2", 3/4", 1", 1.5", 2" Origin: China HS Code: 39174000 Product Description Air &Vacuum Relief ValveAdvantage:1. Air valve is applied for irrigation system or networks of water supply. It evacuates air during pipeline filling and enables large volume air intake in the event of network draining.2. With its advanced aerodynamic design and kinetic orifice, this valve can provide excellent protection against vacuum formation, with improved sealing under low pressure conditions.3. Compact, simple and reliable structure.4. Straight flow body with large diameter orifice -High flow rates.5. Aerodynamic full-body kinetic shield -Prevents premature closing without disturbing air intake or discharge.6. Dynamic sealing -Prevents leakage during operation even under low pressure conditions (0.2 bar).7. All parts are fully corrosion, chemical and fertilizer resistant -Lower maintenance and increased life span.8. Pipeline Filling: During the filling process of apipeline, high air flow is forced out through the kinetic orifice of the air valve. once water enters the valve's chamber, the float buoyed upwards causes the kinetic orifice to close. The unique aerodynamic structure of the valve body and float ensures that the float cannot be closed before water reaches the valve.9. Pipeline Draining: When apipeline is drained, anegative differential pressure is created causing atmospheric air to push the float down.10.. Pressurized Operation: During pressurized operation the kinetic orifice remains closed.Application:1. Main Irrigation Networks -Air relief and vacuum prevention downstream of pumps, along supply lines and at elevations in main irrigation2.·Irrigation Control Heads -Air relief and vacuum prevention at filtration and fertilization stations.3.·High part of Irrigation Pipeline System -Air relief, Prevention of pipe broken as for high pressure air.Company information:We, Chinadrip Irrigation Equipment(Xiamen)co.ltd, is one of the leading professional irrigation system manufacturer and exporter in China for 14 years and we have our own factory,We provide awide range of irrigation products to over 70 countries worldwide with good quality and pretty competitive price.Product Family:1.
