Double hinge flap valve, DN80-DN600

Starting from £82.00

Flap valves are simple non-return check valves that are installed on pipe outfalls or culverts. As fluids can only go through this valve one way, it prevents debris from flowing back, such as sticks and leaves. The backing flange is cleverly drilled to facilitate either headwall or flange mounting.

Orders placed by 4pm have same working day dispatch and next working day delivery, selected models only

Orders placed by 3-30 pm have same working day dispatch and prompt delivery, normally next working day delivery, on selected models only.

Currently we are experiencing issues in achieving next working day delivery in some areas due to HGV driver shortages.
