Flange Gate Valves

Marine gate valves are opening and closing gates, the movement direction of the gate is perpendicular to the direction of fluid flow, and are used extensively throughout the ship.

Marine Gate valves are perhaps the first valve you think of in marine plumbing systems. They are used broadly throughout a ship. Marine Gate valves are prized for their simplicity of form and effectiveness of function. Marine Gate valves get their name from the wedge that lifts up and down inside the body of the valve to allow water or other media to pass, much like the gate in a castle. Gate valves are very good in on/off applications, but should not be used in throttling situations to partially limit the amount of flow because the wedge is not designed to handle that kind of horizontal stress without the valve’s seat to support it.

Marine Gate valves material is cast iron, cast steel and cast copper. It is suitable for occasions requiring low flow resistance and low medium pressure, as well as large-diameter pipelines such as seawater, fresh water, fuel oil, and lubricating oil.

Features : 

The structure is compact, the design is reasonable, the valve rigidity is good, the channel is smooth, and the flow coefficient is small.

The sealing surface is made of stainless steel and cemented carbide for long service life

Using flexible graphite packing, reliable sealing, light and flexible operation

The driving mode is manual, pneumatic, electric, gear transmission

Structural forms include elastic wedge single ram, rigid wedge single ram and double ram
