Marine Cast Steel Angle Globe Valve

Angle Globe Valve – Marine Cast Steel Globe Valve

The body of the angle globe valve is made of cast steel, providing robustness and strength to withstand the demanding conditions often encountered in marine operations. The cast steel construction enhances the valve’s resistance to corrosion and mechanical stress.

The seat, disc, and stem of the angle globe valve are all made of stainless steel. Stainless steel is known for its excellent corrosion resistance, making it ideal for marine applications where exposure to seawater and other corrosive elements is common. The stainless steel components also offer durability and longevity, ensuring long-term reliability of the valve.

The cast steel globe valve design features an angle globe configuration, which allows for effective flow control and regulation. It provides a precise throttling capability, enabling operators to achieve accurate and efficient control of fluid flow in marine systems.

The cast steel angle globe valve conforms to the flange dimensions specified by JIS B2220 for steel pipes. This ensures proper alignment and compatibility when connecting the valve to the piping system, facilitating easy installation and maintenance.

Distinction Between Angle Valve And Angle Globe Valve

An angle valve is a type of valve with an angled body design, typically at a 90-degree angle. It features an inlet and an outlet that are perpendicular to each other. The valve is used to control the flow of fluids in a pipeline by opening or closing the passageway.

The key characteristics of an angle valve include:

• Compact Design:These valves have a compact design, making them suitable for installations where space is limited.
• Quick On/Off Operation: Primarily used for on/off applications, allowing for quick and easy shut-off of the fluid flow.
• Straight-Through Flow: The fluid flow path in an angle valve is typically straight through, which minimizes pressure drop and provides efficient flow.
• Simplified Construction: Angle valves have a simpler construction compared to globe valves, with fewer internal components.

An angle globe valve, on the other hand, combines the features of an angle valve with those of a globe valve. It is designed with an angled body and a globe-style disc and seat arrangement. The disc moves perpendicular to the flow direction to control the flow rate.

The key characteristics of the valve include:

• Throttling Capability: Angle globe valves are primarily used for flow control applications, allowing for precise adjustment of the flow rate by regulating the opening of the valve.
• Excellent Flow Characteristics: The globe-style disc and seat arrangement in an angle globe valve provide excellent flow characteristics, making it suitable for applications where a linear flow characteristic is desired.
• Higher Pressure Drop: Due to the disc and seat design, angle globe valves tend to have a higher pressure drop compared to angle valves. This can impact the system’s energy efficiency and may require consideration in certain applications.
• Greater Resistance to Flow: The internal design of an angle globe valve introduces more resistance to fluid flow compared to angle valves, which can be advantageous in certain applications where flow needs to be controlled precisely.
