Marine Globe valves and angle valves are found wide applications generally in flow regulation duties and also applicable to duties under high temperature pressure.
Product Description
Marine Bronze Valves are a type of valve designed specifically for use in boats and other marine vessels. Made from a combination of copper and tin, Marine Bronze Valves offer superior corrosion resistance, a wide range of temperature ratings, and high strength and durability. This makes them ideal for use in a variety of marine applications, such as fuel and water systems, outboard motors, cooling systems, and more.
Unlike several other types of valves, Marine Bronze Valves have a flat-face design that reduces the chances of leakage. They typically contain an O-ring for further sealing, and in extreme environments, a heat-treated Teflon body gasket may be used for added stability and protection from corrosion. However, because Bronze Valves have a flat face rather than a concave or convex shape, they cannot be effectively used in high-pressure applications.
In terms of installation, Marine Bronze Valves are relatively simple. Most valves are arranged in a straight line and held in place with threaded bolts and nuts. Additionally, most valves come pre-assembled, providing an easy installation process. As with traditional valves, Marine Bronze Valves are manually operated, so they can be opened and closed by hand.
One of the greatest advantages associated with using Marine Bronze Valves is the cost savings they offer. Because these valves are designed with corrosion resistance in mind, they tend to last longer than other valves, reducing the frequency with which they must be replaced. Additionally, the temperature ratings of Marine Bronze Valves can often be tailored to specific conditions, resulting in a more cost-effective solution than a traditional valve.
Marine bronze valves are a popular choice for marine applications because of their corrosion-resistant properties and high durability in harsh environments. Here are some key features of marine bronze valves:
Corrosion resistance: Marine bronze valves are highly resistant to corrosion in saltwater environments, making them ideal for marine applications.
Durability: Bronze is a strong and durable material that can withstand high levels of pressure and temperature.
Versatility: Marine bronze valves can be used in a variety of applications, including seawater intake, ballast control, and fuel transfer systems.
Low maintenance: Marine bronze valves require minimal maintenance and can last for many years with proper care.
Temperature resistance: Bronze has a high melting point and can withstand high temperatures, making it suitable for use in high-temperature applications.
Easy to install: Marine bronze valves are easy to install and can be fitted with a variety of connection types.
Cost-effective: Marine bronze valves are cost-effective and offer a long service life, making them a popular choice for marine applications.
Excellent flow control: Marine bronze valves offer excellent flow control and can be used to regulate the flow of fluids in a marine system.
High-quality construction: Marine bronze valves are constructed with high-quality materials and are designed to withstand the rigors of marine environments.
Marine bronze valves are commonly used in various marine applications, including:
Seawater intake: Marine bronze valves are used to control the flow of seawater into the ship's cooling system.
Ballast control: Marine bronze valves are used to control the ballast tanks that help keep the ship stable.
Fuel transfer systems: Marine bronze valves are used to regulate the flow of fuel in the ship's fuel transfer system.
Firefighting systems: Marine bronze valves are used in firefighting systems on ships to regulate the flow of water.
Waste management: Marine bronze valves are used in waste management systems on ships to control the flow of waste.
HVAC systems: Marine bronze valves are used in the heating, ventilation, and air conditioning systems on ships.
Bilge pumping systems: Marine bronze valves are used to control the bilge pumping system that removes water from the bottom of the ship.
Cargo systems: Marine bronze valves are used in cargo systems on ships to regulate the flow of liquids or gases.

They have a long service life.
They control the flow of the fluid passing through (although not much, and for finer control it is necessary to use control valves with special valve profiles).
They can be held at any level from fully open to fully closed.
The valve lift required to achieve full flow is very small (unlike gate valves).
In angle valves it is possible to change the direction of fluid flow (unlike gate valves).
In globe valves, the fluid being controlled always flows under the valve seat to avoid pressure on the stuffing box and gland packing. Shut-off valves are used for specific applications where strict shut-off requirements exist. They usually use a metal-to-metal sealing surface, but sometimes soft seals such as PTFE or other composite materials that form the sealing boundary are used.
Wheel nut: This is the nut on top of the wheel that helps to secure the wheel to the spindle or stem. It usually has a plain washer underneath.
Handwheel: This is used to open and close the valve. The larger the wheel, the less force is required to operate the valve, as the more torque is applied. This is the reason why wheel spanners are used on ships, because the longer the arm, the higher the torque.
Yoke nut: has a female thread and the stem or stem has a corresponding male thread. When the wheel handle turns the spindle, the stem rises or falls, thus opening or closing the valve.
Gland bolts: these are used to tighten the gland flange and gland bushings, thereby compressing the gland packing in turn and stopping leakage along the valve stem. On board, studs with nuts are usually used as they ar e easier to access and maintain.
Gland flanges and gland bushings: these are used to compress the gland packing and hold it in place. Sometimes they are combined together to form a single unit.
Gland packing: they are cut to the size of the stem and joined end to end, there should be no gap between the two ends otherwise fluid may leak. The packing is staggered so that the cut sections may not overlap each other and provide easy passage. A variety of packing materials can be used depending on the application such as PTFE, graphite tape etc.
