Cast Iron Slide

Cast Iron Slide

Hydro Gate® cast iron slide gates, formerly known as sluice gates, are used to control the flow of fluid through openings under seating or unseating head. Under seating pressure, fluid exerts a force on the front of the gate. The pressure of the water forces the gate slide against the frame which causes the gate to seal tightly. In the design of a structure where cast iron slide gates are used, place the gate so that it will be subjected to a higher seating head whenever possible. When this is done, a lighter gate can be used, and is usually more watertight.

The Hydro Gate Heavy Duty HG560 can be used in the majority of gate applications, and is especially effective in high seating head conditions. We offer custom casting design and analysis for applications requiring higher heads.
