Marine Fire Hydrant Valve
Introduction:
A marine fire hydrant valve is a type of valve commonly used on ships and boats for fire protection purposes. It is designed to provide a source of water for firefighters to use in the event of a fire on board.
The marine fire hydrant valve typically consists of a valve body, a valve stem, and a handwheel for operation. The valve body is usually made of bronze or other corrosion-resistant materials and is connected to a pipeline or water supply source. The valve stem is connected to the handwheel and operates the valve, controlling the flow of water through the valve.

Features of our products |
Achieve results |
|
1. Insufficient raw materials; |
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; |
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; |
1. Made of stainless steel; |
The product has reasonable structure, high safety factor and long service life |
