AS-H Coplastix Weir gate

Alfa Laval AS-H Coplastix® custom built slide and weir gates are especially designed for control of waste, potable and storm water, hydro, industrial, and sea water. The lighter gate provides easier manual operation and requires less horsepower when actuators are employed.

AS-H Coplastix slide and weir gates are built with internal steel matrices that lend strength to the doors. The matrices are then encapsulated by a special formulated composite called “Coplastix”.

All contact faces are made from composite and ultra-high-molecular-weight polyethylene materials for minimum friction, self-lubrication, and a lighter gate. Slide gates exceed the AWWA C563 standard.

Frame mounting options include wall, channel, or flange mount.

Gates are available in configurations anywhere from 8" x 8" (203 mm x 203 mm) up to 144" x 144" (3,658 mm x 3,658 mm).

  • Corrosion-resistant
  • Gate exercising not required
  • Ten times less friction than metal-to-metal gates
  • Disc and seal design prevents gate seizure
  • Half leakage rates of other conventional gates
  • NSF certified materials
  • Ten year warranty

How it works

Gates are opened and closed with the aid of a stem that connects the gate operator to the gate.

The Coplastix® range was designed to exceed all other gate types in longevity without the regular maintenance or exercising. Coplastix materials are lighter, easier to install and extremely durable.

Transform corroded, inoperable gates into smooth operating, corrosion-resistant gates that help put your fluid control system back in operating condition.
