The valve opens as soon as the pressure under the valve seat exceeds the counter pressure. When the pressure is balanced, the valve closes by spring action, which means that in case of a pressure increase, the valve closes on the spring side.
Field of application
All industries. Used when backflow of the product in pipelines must be avoided.
- Profile seals that eliminate gaps and ease ordering of spares due to ID-numbering
- Easy to maintain - the inter-flange design means that the valve can easily be removed from the line
- Flexible design - the valve can be horizontally or vertically positioned
- Reduced maintenance costs - the bearing is very robust and reliable and the valve consists of only a few parts
