Manual Low Pressure Gate Valve for Irrigation Systems

Manual low-pressure Gate Valve for irrigation system: The core of precise water control in farmland water conservancy

Manual Low Pressure Gate Valve for Irrigation Systems, as low-pressure control components specially designed for farmland irrigation, have become the main force for flow regulation in irrigation pipeline systems due to the convenience of manual operation and the adaptability to low-pressure scenarios. It can precisely control the on-off and flow rate of the irrigation water Rubber Expansion Joint, Bellow Expansion Joint, Flexible Metal Hose, Dismantling Joint, Flange Adaptor, Duckbill Check Valve and other accessories work together to build a stable and efficient water flow control network for agricultural irrigation. ​

Core advantage: A powerful manual water control tool for low-pressure scenarios

The core advantage of the Manual Low Pressure Gate Valve for Irrigation Systems lies in its precise adaptation to the low-pressure irrigation environment. The Valve Body is made of materials resistant to low-pressure corrosion. The sealing structure is optimized for low-pressure water flow. When closed, the gate and the Valve Seat fit closely to achieve no leakage. This low-pressure sealing feature complements the one-way Check function of the Duckbill Check Valve - the former actively controls the irrigation water flow, while the latter prevents the irrigation water from flowing back and polluting the water source. At the 分水口 of the main irrigation channel in the farmland, the manual low-pressure gate valve can adjust the branch water volume through the operation of the handwheel. It is combined with the Flange Adaptor to connect irrigation pipes of different pipe diameters, and the Rubber Expansion Joint absorbs the water hammer impact when the water pump starts to protect the valve sealing surface. ​

The manual operation design focuses on the practicality of agricultural scenarios. It does not require complex power devices. Farmers can lift and lower the gate plate by rotating the handwheel. The operation is effortless and the control is precise. In the terraced irrigation system, this manual control feature can be flexibly adjusted according to the water demand of different plots. Combined with the field branch pipe of Flexible Metal Hose , it ADAPTS to the terrain undulation to achieve precise irrigation. The addition of Dismantling Joint facilitates the maintenance and upkeep of the valve during the slack farming season. ​

Structural features: Lightweight and durable design suitable for irrigation

The structural design of the Manual Low Pressure Gate Valve for Irrigation system fully considers the characteristics of the farmland environment. The valve body is lightweight and corrosion-resistant, and can resist the erosion of rainwater and soil in the field. Corresponding to the weather-resistant Rubber material of Rubber Expansion Joint. The gate plate adopts a streamlined design. When fully open, the water flow resistance is extremely small, which can improve the efficiency of irrigation water transportation. This low-resistance feature is consistent with the unobstructed flow channel of the Flexible Metal Hose and can reduce energy consumption loss in long-distance irrigation pipelines. ​

The interfaces at both ends of the valve are mostly connected by flanges or threads, which have excellent compatibility with the Flange Adapter and can be quickly connected to commonly used irrigation pipes such as PVC and PE. In the irrigation system of the greenhouse, the flange-connected manual low-pressure gate valve is used in conjunction with Dismantling Joint, which facilitates the replacement of different irrigation equipment according to the growth cycle of the crops. The Bellow Expansion Joint is installed at the pipe turning point to compensate for minor displacements and ensure the flexible layout of the irrigation pipes inside the greenhouse. ​

Scene adaptation: A versatile water control expert in farmland water conservancy

Field Irrigation Systems are the core application scenarios of Manual Low Pressure Gate Valve for Irrigation Systems. In the continuous irrigation of crops such as wheat and corn, the manual low-pressure gate valve controls the water flow of the branch channel, and large-scale uniform irrigation is achieved through the adjustment of the handwheel. Combined with the mobile irrigation branch pipe of the Flexible Metal Hose, it can reach every corner of the field, and the Rubber Expansion Joint absorbs the vibration of the irrigation pump. Avoid vibration affecting the operation accuracy of the valve. ​

In orchard irrigation, the precise control advantage of manual low-pressure Gate Valves is more obvious. At the main control end of the fruit tree drip irrigation system, the gate Valve regulates the total water supply volume, and is connected to drip irrigation pipes of different specifications in conjunction with the Flange Adaptor. The Duckbill Check Valve prevents the water in the drip irrigation tape from flowing back and blocking. The Dismantling Joint facilitates the regular cleaning of the filter and valve to ensure smooth drip irrigation. ​

In the integrated irrigation and drainage system of farmland, the manual low-pressure gate valve can control the water flow in both directions. It opens for water supply during irrigation and for drainage during the rainy season. It cooperates with the Bellow Expansion Joint to adapt to the slight displacement of the pipeline caused by water level changes. The Flange Adaptor enables the rapid switching between irrigation and drainage pipelines. Improve the comprehensive utilization rate of farmland water conservancy facilities. ​

System synergy: The interlocking efficiency of irrigation accessories

In a complete Irrigation system, the synergy between the Manual Low Pressure Gate Valve for Irrigation Systems and other accessories significantly enhances the irrigation efficiency. In the irrigation main pipeline at the outlet of the pumping station, the manual low-pressure gate valve controls the total water output, cooperates with the Rubber Expansion Joint to absorb the vibration of the pumping station, and the Bellow Expansion Joint compensates for the expansion and contraction of the pipeline caused by changes in water temperature. The three work together to ensure the stability of water supply in the main pipeline. ​

In the field branch irrigation pipeline, the manual low-pressure gate valve is connected to a Flexible Metal Hose through a Flange Adaptor, which can flexibly adjust the irrigation range according to the distribution of crops. Youdaoplaceholder0 Joint facilitates the replacement of damaged hoses and nozzles. The Duckbill Check Valve prevents irrigation water from low-lying areas from flowing back into the main pipeline. This multi-component collaborative system design enables the manual low-pressure gate valve to always play a core role in water control during farmland irrigation. ​

The Manual Low Pressure Gate Valve for Irrigation Systems, with the convenience of manual operation, adaptability to low-pressure scenarios and durable structure, have become the "water control core" of agricultural irrigation. It works in coordination with various Pipe Fittings. Through precise flow control, reliable low-pressure sealing and flexible installation and maintenance, it provides efficient water flow control solutions for different irrigation scenarios such as fields, orchards and greenhouses, helping agricultural production to save water and increase efficiency. ​

Working Principle of Manual Gate Valve:
By turning the handwheel, the threaded engagement between the handwheel and the valve stem causes the stem to advance or retreat. This, in turn, raises or lowers the Valve Plate connected to the valve stem, achieving the opening and closing functions.
