Description

Laminar’s bronze globe valves have been designed with efficient seat and disc designs, making them durable and practical for shutoff and regulating services.

Marine globe valves serve as a means of preventing leakage and controlling surplus seawater on ships.

We offer a variety of screw-down non-return (SDNR) and screw-down Screw Lift (SDSL) globe valves that are well-suited for marine use. These valves have type approvals by ABS, Lloyds, and GL, and we can provide 3.1 and 3.2 certifications upon request.

Our products include a variety of manual, pneumatic, electric, and hydraulic actuators, all of which come with open or close indicators.

The SDNR has two features – one that functions as a basic Stop Valve and another feature that acts as a Check Valve to prevent back-flow.

Laminar globe valves are available for the marine industry as stop valves, screw-down stop and check valves, and check valves in straight and angle types with flanges acc. to DIN, ANSI or JIS.

Laminar offers globe valve with the following designs:

  • with regulate disc
  • with balanced disc
  • with indicator
  • with drain plug
  • with limit switches
  • with electrical, pneumatic or hydraulic actuators

FAQ's

Valves are an essential component in the shipbuilding industry as they regulate and control the flow of various substances within a ship’s systems, such as the flow of water, gasses, vapours, slurries or semi-liquid mixtures.

This regulation is necessary for ensuring the proper performance of onboard operations.

Marine valves offer accurate pressure and flow control within the system and faster installation by reducing the number of pipes and connections needed, resulting in cost and time savings during construction.

Globe valves are commonly used on ships, particularly in bilge suction lines, because they effectively handle varying pressure.

The valve regulates fluid flow and features a globe-shaped body containing the valve seat and disc.

A perpendicular to the valve axis disc and a valve seat make up a globe valve. The valve opens when the disc is pulled away from the valve seat, and a space develops between the disc and the disc ring.

The globe valve’s ability to regulate fluid flow through throttling is advantageous. Globe valves can operate as non-return valves to prevent reverse flow.

For example, the JIS globe valve is used in a variety of marine applications – from controlling the flow of cooling and ventilation systems to ensuring proper operation of ballast systems and oil cargo pumping systems.

These valves are also suitable for shipside duties such as thruster retraction, sewage treatment units, bilge system pumps, and firefighting systems.

Globe valves used in ships are made from materials that can withstand the corrosion caused by regular contact with seawater.

The following are key features of globe valves commonly used in marine settings.

  • There are multiple variations available, each with unique benefits.
  • Globe valves possess superior shutdown capabilities.
  • When comparing ball and globe valves, it has been found that globe valves have a better throttling capacity.

Engineers should conduct regular inspections when dealing with marine globe valves, even though their maintenance requirements are lower. Here are some essential factors to consider.

  • The gland area of a globe valve may experience wear and tear from frequent use, requiring parts replacement for optimal sealing.
  • If the valve is not frequently operated, it may experience temporary cycling.
  • It is crucial to consider the potential damage to the valve seat if it is frequently opened and closed.
