Alfa Laval: Coplastic Gates®

With Coplastix® Flow Control products from Alfa Laval (previously Ashbrook Simon-Hartley) we offer the performance leader in fluid control equipment for the world market.

Proven by decades of dependable performance in a wide variety of applications, Alpha Laval Coplastix® sluice gates, stop gates and logs, and flap valves offer significant benefits above and beyond similar cast iron and stainless steel products.

Replace corroded, inoperable gates with pristine, smooth operating, non-corroding gates and put your fluid control system back into operating condition.

When you retrofit your troublesome cast-iron, aluminum, stainless steel and fiberglass gates with trouble-free Coplastix®technology, you effectively eliminate 90% of potential gate problems. Coplastix® technology eliminates the problem of frozen gates because Coplastix® material will never corrode and reduce gate friction by a factor of 10.  Coplastix® is exceptionally watertight, exceeding AWWA requirements. Coplastix®  is not subject to thermal expansion and can be used in ambient temperatures ranging from 50ºF below zero to plus 180ºF.
