Floodgates
Prime Floodgates
Prime Composites floodgates are also known as reflux valves, tidal flaps, gas checks, croc stops and frog flaps.
They are also referred to as King Valves, Hume-King ,Rocla-King and Hardie-King floodgates.
Application
Prime ring mount Floodgates are a non-return valve used extensively around Australia and internationally and are regularly specified by water authorities, councils and design engineers. They are used for purposes such as:
- Prevent children from entering dangerous storm water lines
- Prevent back-flow
- Ideal for reclamation of low lying areas
- Prevent entry of animals and vermin
- Prevent tidal inundation
Advantages
Our floodgates have numerous advantages such as:
- Excellent resistance to sea water, sewage and a wide range of chemicals
- Extremely durable
- UV stable
- Because they are fibreglass and have only small metal components they do not have any scrap value
- Quick and easy to install
- Due to the pin location on all our gates, they will seal effectively when fitted to the normal vertical end of the pipe
- Cost effective
- If chemical contact is expected, please advise us
Construction
Our range of floodgates are produced from light weight fibreglass reinforced polyester. The use of 316 grade stainless steel hinge pins make Prime Floodgates suitable for the most demanding environments.
Handling
During transit and storage, the gate must be laid flat on an even surface or distortion of the gate may occur (this is not a concern once the gate is fitted to the pipe).
Types of Floodgates
We have many different models of floodgates to suit your individual requirements.

Ring Mount Floodgates
Our ring mounted floodgates are fitted to a collar via a hinge. The collar slides over the end of the pipe and is epoxied in place making it quick and easy to install. A neoprene seal is adhered into a moulded recess in the face of the mounting ring, worked to fine tolerances in the final stages of production, the flap then seats against the seal.
Wall Mount Floodgates
Our wall mounted floodgate is very similar to the ring mounted floodgate but has been fitted with a flange which is bolted to the wall. This unit is ideal for installation onto pit walls and headwalls.
Flanged pipe Floodgates
Our flanged pipe floodgate is very similar to the wall mounted floodgate, however the difference is that the flange pipe floodgate is drilled to specific bolt patterns to match flanged metal pipes.
Bolt-on top type Floodgates
Our bolt-on-top type floodgates have a neoprene seal embedded into the face of the flap, this seal contacts the face of the pipe to create a seal. As the name suggests this unit bolts onto the top of the pipe.
Box Culvert Floodgates
We can also produce square and rectangular floodgates to suit box culverts in wall mounted and bolt-on-top type. Due to the material selection our gates will operate in the most demanding environments.
