Marine Valves

Commercial Marine Valves and Automation

Marine valves are essential for fluid control and handling on your vessels and it’s vitally important your ship is installed with the correct valves.

Tailored to your specifications

At the Lloyds approved foundry, we can provide you access to bespoke production, as well as immediate dispatch of a wide range of valves to your exact location.

Specific valve details:

  • Valves from 15mm to 600mm
  • Unmachined castings from 0.1kg to 500kg
  • Materials: bronzes, alu-bronzes, non-ferrous materials
  • Made to British, DIN, ISO and JIS Standards
  • ISO 9001 approved

All valves can be produced to your own specification.

We understand that valve replacements and repairs work to keep your ship operating and making a profit, which is why we’re the perfect agents to manage your project.

Marine Valve Types and Purposes

It’s essential the right marine valve is manufactured, purchased and installed on your vessel for proper fluid control.
Here is a breakdown of the main valves and their functions:

Ball Valves

Suitable for liquid control within the ship’s hull, ball valves have more functionality than gate valves and offer rapid action. Normally designed with NPT (tapered) threads.

Butterfly Valves

Butterfly valves are quarter turn valves with rotating metal discs mounted inside a pipe. They regulate water flow and can also be used to prevent it entirely.

Check and Non-Return Valves

Check valves are designed to allow flow in one direction, whilst prevent flow in another direction. This is known as ‘back flow’ or ‘reverse flow’, and are also self-automated. Typically manufactured using stainless steel.

Storm Valves

Similar to check valves, storm valves allow flow in one direction and prevent it in another, with the ability to function perfectly in heavy seas as they have a closed position. The ability to close the valve is usually operated by a hand wheel.

Gate Valves

Gate valves allow you to control flow by adjusting the pressure; when required you can maximise or minimise water flow through pipes and valves.

Custom Valves

From size, shape, material and functionality, we can manage the design and manufacture of custom or bespoke marine valves for your vessels.

Additional valves available: Wedge Gate Valves, Plug Valves, Diverter Valves, Strainers, Glove Valves & Hydrant Valves.

Once you have ordered your marine valves through Calvey Marine, we ensure the manufacture, delivery, installation and maintenance is carried out quickly and with minimum disruption to your vessel.
