812/812X

The 812X non-return disc valve is designed for high performance in both pressure and temperature conditions, making it suitable for a wide range of applications. It can operate in any position and is compact in design, allowing for easy installation and dismantling while saving space. The valve is engineered to minimise head loss and prevent water hammer, ensuring smooth and efficient operation. The closing system features back axial guiding with a return spring, along with lateral guiding by three or four ribs for sizes DN 15 to 100, while sizes DN 125 to 200 utilise back axial guiding with a return spring. The valve provides metal-to-metal tightness, with the obturator sealing against a machined seat for reliable and durable performance.
