Marine Storm Valve

Introduction

A marine storm valve is a type of valve designed for use on ships and other marine vessels. It is used to prevent seawater from entering a vessel's interior through openings such as sea chests, intakes, and discharge outlets during rough weather or heavy seas.

The valve is typically installed on the outside of the hull and is designed to automatically close in response to water pressure. The valve's closing mechanism is typically activated by a float or other mechanism that senses the rising water level and triggers the valve to shut.

Marine storm valves are an important safety feature for ships and can help prevent flooding and damage to the vessel during severe weather conditions. They are also required by many maritime safety regulations.

Advantage

1. High-Quality Material: Marine storm valves are made of high-quality materials, such as bronze or stainless steel, which makes them resistant to corrosion and rust. This ensures durability and long-lasting performance.

2. Superior Design: The valve design ensures maximum efficiency in water flow control, even in the harshest marine environments. The valve can operate in any position, allowing for easy installation.

3. Reliable Operation: Marine storm valves have a proven track record of reliability and trouble-free operation. They are designed to handle the demands of the marine industry, where safety and reliability are paramount.

4. Versatility: Marine storm valves can be used for various applications, including ballast systems, bilge systems, and firefighting systems.

5. Easy Maintenance: The design of marine storm valves allows for easy maintenance and repair, minimizing downtime and reducing maintenance costs.

6. Safety: The design of the valve ensures safety in marine environments by preventing water from entering the vessel in case of a breach. This feature is critical in preventing flooding and potential sinking of the vessel.

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
