Deck access boxes and sounding tubes are used to take the measurement of fluid in the tanks. They are also used for reach rods to lower decks. They come in sizes from 1-1/2 inches to 2-1/2 inches and are available in steel body or stainless body and with bronze plug with square or rectangular holes. The wrenches used to open these boxes are also available, if needed. W&O’s experienced professionals can help assure that you get the precise products you need for your unique applications.
Scupper valves—also known as discharge-check or storm valves—are basically swing-check valves with a closing device. A closing device is usually a hand wheel, but it can also be actuated. Scupper valves are usually found on ships in sanitary piping systems that have a ship-side exit and prevent seawater from entering the system during a heavy sea. They are also used on overboard-discharge lines. W&O’s offers scupper valves in a variety of types and sizes to fit all of your applications.
Eductors are used to pump liquids from chain lockers, tanks, cargo holds, bilges, lockers or similar spaces. Pressure through an inlet creates pumping suction from one side and discharge out the other side. Suction/discharge can be a straight-through or angle arrangement. W&O’s large inventory includes eductors in bronze with flanged or threaded connections for portable use or permanent installation and in a wide range of styles and sizes.
Sight flow indicators, or drip tubes, are an economical way to provide quick and reliable evidence of flow with a systems line. If there are any flow problems in the line, the sight flow indicator will allow for visual monitoring of the systems line. W&O offers many types of sight flow indicators to meet various conditions of pressure, temperature, fluid types and mechanical dimensions.
A remote valve-operator system uses a mechanical connection to operate valves from a remote location. Rigid rod components are used when operating speed is slow or intermittent and rotates in either direction. W&O can help with design factors that are used to determine the specifications of suitable rigid-rod components in a remote valve-operator system.
Public-health valves, also known as backflow preventers, are installed in potable water systems to protect the water from potential hazards. Backflow devices are required by law and must be installed in accordance with public-health codes.
Quick-opening and self-closing valves are used in many shipboard applications. Quick opening valves operate with a sliding stem and open faster than traditional hand-wheel-operated valves. Many of these valves are available with spring handles or weighted levers to insure the valve will close when left unattended. Solenoid valves can also be included in this type of valve as they are electrically operated, quick-opening valves.
The spectacle blind provides positive, permanent shutoff in a piping system where there might be a potential leaky valve. When the blind end of the spectacle plate is clamped in position, media cannot leak to the downstream side. This allows workers to fix the leak and avoid any potential hazards from the upstream side.
Suction bellmouths are designed to maintain efficient suction during final stripping of liquid cargo tanks. Their unique design minimizes hydraulic loss and prevents vortex and gas formation when pumping liquids from the bottoms of the tanks.
