High reliability, low maintenance composite slide gates

  • No binding , and meet or exceed AWWA C563 leakage parameters
  • Ten year manufacturer’s warranty
  • Easy-to-operate gates do not require exercising
  • Custom designed to your application

Continuing the high quality you would expect from the original Ashbrook designs, Alfa Laval AS-H Coplastix® composite stop gates (hand stops) slide gates are light, yet durable, to ensure reliable operation. Their corrosion resistant material provides years of maintenance free service.

How it works

.

Gates are opened and closed with the aid of a stem that connects the gate operator to the gate.  They can be opened and closed manually or with the assistance of an actuator.

AS-H Coplastix® slide 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).

Features and benefits

  • 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
  • Ten year warranty
