Our technical features of the foot valves
The foot valves of Lasso Technik AG are equipped with a membrane to prevent the back flow of liquids and gases. When the membrane is closed, the noise level is low and water hammer is avoided. The valve guarantees a safe closure even in the case of granular liquids (sandy water). In addition, our foot valves act as raw filters to protect pumps and systems. We guarantee a long product life due to the absence of mechanical or electronic moving parts subject to wear and tear.
