Marine Angle Globe Valve

Introduction

A marine angle globe valve is a type of valve that is commonly used in marine applications, such as on ships and offshore drilling rigs. It is designed to regulate the flow of fluids, such as water or oil, within a pipeline.

Marine angle globe valves are typically made from durable, corrosion-resistant materials such as bronze, brass, or stainless steel. They are often used in critical applications, such as on main propulsion systems or in firefighting systems, where reliability and safety are paramount.

Feature

Some common features of marine angle globe valves include:

1. Angle body design: The valve has an angled body that allows it to be mounted in tight spaces or where the piping is at an angle.

2. Bolted bonnet: The bonnet of the valve is bolted to the body, ensuring a tight seal and easy maintenance.

3. Renewable seats and disc: The valve has replaceable seats and disc, making it possible to repair or maintain the valve without replacing the entire unit.

4. Non-rising stem: The stem of the valve does not rise when the valve is opened or closed, making it suitable for use in limited space applications.

5. Flanged end connection: The valve has a flanged end connection that allows for easy installation and removal.

6. Corrosion-resistant material: The valve is made of materials that are resistant to corrosion, making it suitable for use in marine environments.

7. Pressure rating: The valve has a pressure rating that specifies the maximum pressure at which it can operate safely.

Advantages

1. Versatility: Marine angle globe valves can be used for a wide range of applications, including throttling and regulating flow.

2. Durability: These valves are designed to withstand harsh marine environments and can resist corrosion and erosion.

3. Easy to Operate: Marine angle globe valves are easy to operate, and their design makes them less prone to damage.

4. Good Flow Control: Globe valves are known for their precise flow control, allowing for easy adjustments.

5. Leak-proof: Marine angle globe valves have a tightly sealed construction, preventing leaks and fluid loss.

6. Low Maintenance: Globe valves require little maintenance and are easy to disassemble, clean, and repair.

7. Efficient: These valves have a minimal pressure drop, allowing for high flow rates, which can save energy and reduce costs.

8. Long-lasting: Due to their sturdy construction, marine angle globe valves have a long lifespan, reducing the need for frequent replacements.

Low quality product features

Consequence

Features of our products

Achieve results

1. Insufficient raw materials;
2. The processing method is not standard

The wall thickness is uneven, the material distribution is uneven, the valve body is easy to be damaged, and the service life is short

It is processed in strict accordance with the standard, with uniform wall thickness and material

The product has high safety factor and long service life

1. Made of iron and carbon steel;
2. Use the recovered scrap valve to repair and then sell it again;

The hardness and accuracy of the valve cannot meet the needs of use, and the shell is easy to crack, resulting in running, emitting, dripping and leakage, and even causing oil and gas pipeline explosion

Select high-quality materials according to customer needs, and make new products in strict accordance with standards

The hardness and accuracy of the valve meet the standard quality requirements to ensure the normal operation of the equipment

To improve profit margin, purchase cheap unqualified bolts

Unqualified valve bolts lead to safety hazards, which is easy to cause accidents

Make new valves in strict accordance with the material requirements of customers, and never substitute inferior products for good ones

Meet the hardness and accuracy requirements of standard valves, ensure the quality of valves and ensure the normal operation of equipment

Flange manufacturing quality is poor, with cracks, pores, insufficient thickness and other problems

It leads to wear resistance and poor pressure bearing of the valve, and the valve is prone to quality problems, which makes

short service life

Adopt standard bolts with quality assurance in strict accordance with customer requirements

Improve safety factor and prolong service life

In order to reduce the cost, cast iron valve core is used instead of bronze valve core

Cast iron valve core is easy to be corroded and damaged

Select standard materials in strict accordance with customer requirements

The product structure is reasonable and the safety factor is high

In order to reduce costs, ordinary round steel valves are used instead of stainless steel valves

1. The diameter of valve rod fails to meet the requirements;
2. The performance of alternative materials is unstable, without heat treatment, the quality can not meet the standard, and the service life is short

1. Made of stainless steel;
2. The diameter of valve rod meets the design requirements;
3. High temperature quenching and tempering heat treatment

The product has reasonable structure, high safety factor and long service life
