The Robert H. Wager Company, founded in 1933, spans 79 years of service to the maritime industry. We offer our customers a full range of services, from design and manufacture to sales and service of vent check valves and deck equipment.
Inverted vent check valves
We stock a full line of rugged marine valves designed to withstand the harsh environments found at sea. Our inverted vent check valve mounts to a gooseneck pipe, allowing for ventilation in the open position, and our patented float design prevents contamination of the tank cargo by saltwater during heavy seas.
When in port during loading or unloading cargo, our vent valves provide the necessary protection from pressure build-up on bulkheads and tanks. We stock galvanized steel, stainless steel, bronze and aluminum valves. Our inverted vent checks are ABS approved.
Vertical vent check valves
Our vertical vent check valve mounts directly to the vent piping on the deck, and provides a tight seal to prevent water from entering the lower bulkheads. Our high-density polyethylene disc float seals tightly to prevent water from entering the tank. Additional options include manual closures and dual outlet covers. Available materials are galvanized steel, stainless steel and aluminum. All of Wager's vertical vent check are ABS approved.
In-line vent check valves
Our in-line vent check valves mount vertically or horizontally in areas that are not accessible to deck mounts, and are best used where venting is required and aesthetics are essential. Vertical in-line valves are available in galvanized steel, bronze and aluminum. Our horizontal vent checks have been designed to oil rig specifications and are available in stainless steel only.
Odor control vent valves
Wager's marine odor control vent valve is designed to allow for ventilation of black and grey water tanks while providing necessary odor control at the tank's location. The valve connects to a gooseneck pipe, or can also be vertically mounted on the ship's deck with a rain shield.
A media canister containing 12lbs of odor controlling media scrubs the air before it is expelled into the atmosphere. Media pellets are engineered to be highly effective in removing H2S gas, and are non-toxic and landfill disposable. The valve is available in 4in or 6in flanged connections, with the additional option of metric flanges.
Wager stocks three variations of deck drains: standard, stainless steel, and heavy-wall. Our standard version has a removable cast bronze strainer plate. Commercial vessels and yachts may order highly polished stainless-steel strainer plates for a more pleasing aesthetic.
Our heavy-wall deck drains are available in both straight and angled configurations. A cast bronze strainer with trap and baffle allows for drainage while preventing sewer gases from escaping into the atmosphere.
Stainless steel sounding tubes
Wager's stainless-steel sounding tubes are threaded with a bronze or stainless-steel plug, and secured with a neoprene gasket for a tight fit. Our standard plugs or venting plugs are available in all sizes, and allow for the release of stored gases without the need for plug removal.
