Design Features

• Size range: DN 100-DN 1000
• Pressure rating: PN 10 | PN 16 | PN 25 丨 PN 40
• The silent check valve is designed to meet the characteristics of cushioning and quick closing. The spring is loaded on the flap to shorten the closing stroke, providing a quick response to flow changes.
Therefore, water hammer and impact noise are minimized for fast closing
• Full-pass design provides full flow area around the disc when the disc is in the open position, ensuring minimal head loss
• Valves are suitable for high flow conditions
• Can be mounted on vertical or horizontal pipes
• Flange connection dimensions in accordance with EN 1092-2
