FLAP VALVES - HDPE material - WALL MOUNT

Flap-Valve wall mount design, fasten directly to the wall at the outfall.

A flap valve gate when placed in front of a discharge pipe or culvert, creates a one-way flow seal. When there is head pressure from behind (inlet pressure) the flap door opens and discharges the water. When the water head, front pressure increases, the flap door will close.

Flap Valves WA.PTK-G wall mount valves come with chemical bolts for anchoring the unit to the wall. A wall gaskets placed between the back flange collar and the wall provides leak protection. The unit sets vertically flush with the wall. The flap door operates with just a few mm of head differential pressure.

Water flows through the valve to allow water build up to escape but prevents rising water levels from the door side to flow back up the pipe.

Available for all pipe and opening sizes: contact Westatlantic

HDPE Flap Valves Specification for WA.PTK-G model :

Application

Non-return flap valve suitable for emergency application/ flood protection.

Flap Valves standard door pressures

Head pressures: one meter water head on a permanent bases. In Flood water five meter water head for 72 hours measured from bottom of opening. Higher pressure doors are available.

Flap Valves wall mount models: Fit all American and International pipe sizes. The flap door opens with just a few millimeters of differential water pressure.

Flap valves HDPE models are easy to handle and install. HDPE material valves are highly resistant to aggressive fluids. 316L stainless steel is used for all metallic parts, E.g. hinges, hooks etc.

Flap valves WA. PTK-G wall mount models mount flush with the wall. They are suitable for below and above the waterline. They prevent back flow in times of emergency and allow outflow when the upstream pressure exceeds the pressure on the door. Just a few mm of water will allow flow.

The valve is not hindered by its own weight and will open with very little differential pressure. Differential opening pressure are less than 10 mm water column.

Models PTK-G are normally installed above the water line, but also prevent back flow back flow in times of sudden increases in water levels due to heavy rain and flooding

Advantages of HDPE flap valves:

No corrosion

  • Good chemical resistance against acids salts and alkalis, many solvents, oils, etc.
  • High UV protection for outside use
  • Suitable for use between -50ºC and +70ºC
  • Dimensional stability, low density and lightweight
