Althon manufacture orifice plates in galvanised or stainless steel to restrict and regulate the flow of water. We manufacture orifice plates to suit all pipe sizes and provide the opening in the plate to your specified dimension and position required. We typically provide flat orifice plates to bolt directly onto a flat surface or wall. We can send out all necessary fixing materials and an EPDM seal with our orifice plates on request.

Althon also manufacture curved manhole orifice plates to fit directly onto the wall of manhole chambers. Alongside our standard range of manhole orifice plates we also manufacture orifice weir plates for manholes in galvanised or stainless steel.

We also offer orifice plates factory fitted to our precast headwalls and precast concrete inspection chambers.
