Marine Butterfly Valve

Marine Butterfly Valve

Introduction

A marine butterfly valve is a type of valve commonly used in marine applications to regulate or control the flow of fluids, such as water, oil, or gas. It is named after its shape, which resembles a butterfly, with a circular disc that rotates to allow or restrict the flow of fluid through the valve.

One of the advantages of the marine butterfly valve is its compact size and low weight, which makes it suitable for use in marine applications where space is limited. It also has a lower pressure drop compared to other types of valves, which means that it can handle higher flow rates with less resistance.

Overall, the marine butterfly valve is a commonly used valve in marine applications due to its compact size, low weight, and low pressure drop. However, its use should be carefully considered based on the specific application and operating conditions.

Feature

1. Corrosion-resistant: Marine butterfly valves are made from materials that are resistant to corrosion caused by seawater and other marine elements.

2. High-strength: The valves are designed to withstand high pressures and extreme temperatures, making them ideal for use in harsh marine environments.

3. Low maintenance: Marine butterfly valves require minimal maintenance, thanks to their simple design and high-quality materials.

4. Easy to operate: The valves are designed for easy operation, with a simple lever or gear mechanism that can be easily turned by hand.

5. Wide range of applications: Marine butterfly valves can be used for a variety of applications, including controlling the flow of water, fuel, and other fluids in marine vessels.

6. Durable: These valves are built to last, with rugged construction that can withstand the rigors of marine environments.

7. High flow capacity: The valves are designed for high flow capacity, allowing for the quick and efficient transfer of fluids.

8. Cost-effective: Marine butterfly valves are a cost-effective solution for controlling fluid flow in marine vessels, with a low initial cost and minimal maintenance requirements.

Configuration Options

Name of Parts	Material	Advantages/Disadvantages
Valve Body	Grey cast iron	The most common material in butterfly valves, mainly used in water systems, is easily corroded, has a short service life and is cheap.
	Ductile cast iron	The performance of the butterfly valve is comparable to that of carbon steel. It is generally used in water system pipes, and it is also a very widely used material in water systems at present.
	Carbon steel	It can also be used in water systems, but it is not used much. Carbon steel butterfly valves have high temperature and pressure resistance. Generally, hard-sealed butterfly valves are mostly made of carbon steel.
	Stainless Steel	It has good anti-corrosion and anti-corrosion properties, and is also mostly used in pipelines that need anti-corrosion and anti-rust, and the cost is relatively high.
Valve Disc	Stainless Steel	Stainless steel has a strong ability to resist tension, wear and corrosion. Stainless steel is much stronger than copper in material. Stainless steel will not produce corrosion, pitting, rust or wear and high temperature resistance.
	Bronze	Bronze has excellent low temperature resistance, good corrosion resistance, wear resistance, casting and excellent mechanical properties
Valve Seat	EPDM	Suitable medium -20-120℃ water, steam, etc
	NBR	Applicable medium 0-80℃ oil class
	PTFE	Applicable to corrosive media below 200℃
	Hard alloy	Suitable for high temperature and high pressure environment
Hand Wheel	Cast Iron	Cost less than bronze and cast steel

Specific Differences Between us and Other Suppliers

Comparison
Product Picture of other low quality supplier		Product Picture of our factory
Other low quality supplier	Consequence	Our Factory	Result
In order to reduce costs, omit raw materials and reduce internal quality, resulting in the thin wall of the valve body that occupies the main body of the valve.	Leaving a safety hazard, the thin wall is easy to break or leak the valve at high temperature and high pressure or during operation.	Strictly in accordance with the standard processing, uniform thickness, and material	Use with confidence, meet user needs, and the product has a long service life
Rubber valve seat is made of waste rubber	Not durable and waste of resources, once the valve seat is worn and damaged, the entire valve is considered waste	The rubber valve seat is made of a new type of super wear-resistant rubber, and can be reused	The rubber material is super wear-resistant and can be reused, and the valve can be used for a longer time
The valve seat, valve stem, and valve disc are all fixed configurations, which cannot be disassembled and assembled individually, and cannot be replaced with individual parts.	If a part is damaged, it can only be replaced as a whole, wasting resources and increasing costs	Seat, stem and disc are standard parts	Replacing accessories is simple and easy, saving time and effort. Not only reduce costs, but also save resources for the country
