Effective flow control

We offer two types of dredge valves: a rubber ring valve to open and close a line on board of a vessel or in an installation on land and a regulating valve to control flow in dredge pipe systems. All dredge valves are basically made up of a casing with flanges to mount the dredge valve in the pipe system, a control system that operates the slide (hydraulic or manual) and position indicators.

Why choose our dredge valves?

optimal design for gate and rubber rings for less maintenance and downtime
wear and tear parts available from stock
compact rotating design for areas with limited space

Less maintenance and downtime

Due to the design and material of the gate and the rubber rings - which give a minimal gap between the rings to prevent sanding and downtime of the dredge valve - less maintenance is required and downtime is decreased.

Wear and tear parts available from stock

All wear parts for the standard dredge valves are available from stock for a quick solution and service to our customers.

Innovation: compact rotating design for areas with limited space

Our Pendulum valve - a new design - has a significant lower built in height which allows for usage in tight spaces. The Pendulum valve uses the same wear and tear parts as the normal gate valves. Read more about this innovation in our blog.

Gate valves: how to redefine an industry standard

"What we discovered was that the easiest way to save space was to take off the hydraulic cylinder – from the top of the valve – and put it in front, thereby lowering the height (by approximately 30%)."

Two types of dredge valves

Rubber ring gate valves
Rubber ring gate dredge valves have been designed for operation in either fully open or fully closed position. The reinforced rubber ring seal set provides perfect sealing under even the most adverse dredging conditions. The rubber rings are pre-tensioned to prevent siltation and to provide a smooth and free passage of material in the pipeline.
Regulating valve
The regulating valve is used to regulate the flow of the dredge mixture. It positions the wear resistant slide so as to control the passage of the mixture. The underside of the passage is flush and limits wear. The installation assures a fully watertight pipeline.
