Diaphragm valve VESTA® series

shut-offfor waterseat

Unlike other valve types, seat valves possess a natural draining action. The sectional diagram illustrates the way the valve seats are configured to ensure a natural gradient between the valve connectors. Being on a level with the piping, the body’s inside contour and the natural gradient between the body levels combine to ensure that the valve body drains completely. Seat valves feature no barriers that could obstruct the drainage of residual fluid, allowing it to accumulate and form a breeding ground for microorganisms. Inside surfaces all feature wide-radius geometry to assist fluid drainage. The VESTA® sterile valve is designed with a self-draining shape. The unit’s design with its right-angled connector arrangement and the body portion between the pipe levels ensures easy, foolproof alignment when fitting.
