Complete Guide to Globe Valves for Naval Use

You’re on a cruise ship and the toilet suddenly overflows with sewage water. The smell of stinking wastewater fills your room. You and the wife exit your quarters after feeling ill. Over the speaker, the captain assures passengers that the crew is fixing the problem.

You begin to worry. You’re not sure if the ship suffered structural damage. You begin to wonder if the ship will sink. 

Should you panic?

Panic is unnecessary, but the problem started with a faulty globe valve. What is a globe valve? It’s a valve that regulates the flow of a liquid. Globe valves have a disc that allows operators to regulate flowing liquid.

On a ship, you can normally find a globe valve near bilge suction lines. Faulty valves can cause pressure and fluid control issues. Such instability can cause backflooding. 

Globe valves for naval use come in different forms. For instance, there are also different types of globe valves: angular valves, Z-type valves, and Y-type valves. This article will show you how globe valves help ships operate efficiently. Keep reading if you want to learn more. 

Globe Valve Types

Certain globe valves serve different purposes that can mitigate safety hazards on a ship or within pipeline infrastructure. For example, certain valve types are more suitable for high-pressure flow lines. Others address pressure drops.

  • Angular Valves: This valve has inlet outputs and outlet outputs fixed at right angles. The fluid flows through the valve in a right-angled manner. Then, it’s dispelled downward symmetrically. An angle globe valve is ideal for high-pressure situations. Without the high pressure, angular valves function in the same way as Z valves.
  • Z Valves: Z-type valves are the most common valves. Operators typically use it to manage water flow. A globe valve diagram will show a Z-shaped partition in the bulbous component of the valve. The stem and the disc shift to the valve body at right angles.
  • Y Valves: The Y-type valves address pressure dips. Engineers fixed the stem and seat at 45-degree angles relative to the axis. This allows a straighter fluid path, mitigating the valve pressure.  

More importantly, each valve plays an integral in preventing accidents that can prevent property damage and personal injury.

Safety Preservation

For emergency suction lines, globe valves regulate fluid pressure and manage excess water. To prevent backflooding, operators use globe valves in a non-return capacity. This means that the disc isn’t affixed to the spindle. 

The non-return valve fosters the pumping of bilge water into the sea. Further, non-return valves prevent seawater from entering the ship. Also, the suction non-valves stop backflooding from the sea to the bilge. Further, it stops backflooding between watertight compartments. 

Globe Valves for Naval Use and Beyond

Globe valves keep excess water from entering a ship. They also dispel wastewater and maintain quality hygiene on ships. When determining the number of valves needed, the ship size and application are two important factors to consider. Overall, globe valves for naval use enhance waste treatment, plumbing, and water management. 

Regardless of the valve, choose from a reputable provider that offers high-quality valves. There’s more to consider when assessing any type of shutoff valve. Contact us today to learn more about commercial shutoff valves.
