Descripción del producto

The slip-on duckbill valve is a revolutionary design for backflow prevention.

It offers low cracking pressure to eliminate standing water and very low headloss.

Liwei check valves are cost-effective because they require no maintenance or repairs and have a long service life.

The valves are excellent replacements for metal flap gate valves for they will not warp or freeze and are virtually maintenance free.

The valve is slid onto the pipe and held in place with steel or stainless steel band clamps, eliminating flanging costs.
