The Go-Sep™ GFV-P™ flap gates are designed to be installed to a pipe using a coupler, fusion- or butt welding.

Flap gates prevent backflow for stormwater and wastewater in pipe systems, chambers and basins. Flap gates are typically used in applications where there is a risk of flooding or backup, such as in storm-water management systems, treatment plants, ports, rivers and coastal areas.

LecoTech Flap Gate is made of exceptionally strong & tough High Density Polyethylene (HDPE) Pipe and Sheet. A small differential pressure on the back of the gate causes it to open automatically to allow discharge through levees, sewer lines or drainage conduits.

We are dedicated to designing and fabricating high-quality HDPE flap gates that meet the industry's quality standards. Explore our range of HDPE flap gates today.

HDPE Flap Gates are devices used in water management systems to control the flow of water in channels, culverts, and drainage systems. These gates are specifically made from High-Density Polyethylene (HDPE), a durable and corrosion-resistant material.

Flap gate valves are used as back flow preventers and are available in a large range of sizes and types. There design is an economical response for backflow. Fusible HDPE, Stainless Steel.

The Series 5900 Drainage (Flap) (Tide) Gates are a corrosion-resistant, rustproof, automatic drainage gate designed for use where light weight, corrosion resistance or tight sealing is foremost. Seating heads to 30 feet. Flatback for mounting to headwall, or flangeback to mate with wall thimble. Spigotback for mounting to pipe. (CMP, PVC, HDPE).

Spirolite HDPE Wall Mounted Flap Gate (Square) 1200MM (L) x 1200MM (H) Application Automatic operating control by hydro force. To prevent back flow from storm rain in main river flow into lower land area.

The Series 6200 Heavy Duty Flap Gate is designed to permit the outflow of water from a pipe or a structure to a body of water while preventing backflow of the same. It is frequently used in reservoirs, tidal basins, ponding basins, pump stands and storm drain systems where seating heads are less than 50 feet.
