Pressure Sustaining válvula / Pressure Relief válvula / Hydraulic Control válvula / riego válvula

The IrriNex Hydraulic Pressure Sustaining & Relief válvula is a hydraulically operated diafragma control válvula designed to maintain a preset minimum upstream pressure, also known as back pressure. When the upstream pressure falls below the preset value, the válvula gradually closes. When the pressure rises above the preset level, the válvula opens fully to maintain stable system operation.

Built with a full-bore Y-pattern válvula body, the válvula provides high flow capacity while minimizing pressure loss. The flexible diafragma and guided válvula core provide accurate and stable regulation, smooth closing and low presión de trabajo requirements. Its corrosion-resistant plástico construction is designed for reliable operation in riego and water control applications.

The válvula can also be integrated with electrical control using AC, DC or DC pulse signals for remote opening and closing. A manual control mechanism allows local válvula operation when required.
