Marine Valve

Marine Valve

1. Marine Valve Introduction:
Marine valve is a ship part used to control the pressure, flow rate and flow direction of fluid in ship pipeline to meet the ship's environmental conditions. It is the control device of fluid pipeline. Its basic function is to connect or cut off the flow of pipeline medium, change the flow of medium, change the flow direction of medium, adjust the pressure and flow of medium, and protect the normal operation of pipeline equipment.

Marine valves are an essential component of ships and boats, as they are used to control the flow of fluids such as water, fuel, and oil through the various systems on board. Marine valves can be found in a wide variety of marine applications, including seawater cooling systems, ballast systems, fuel systems, and fire-fighting systems, among others.

The nominal diameter range is from 6 mm to 1500 mm. The working pressure range is from 0.25 Mpa to 25 Mpa. The materials are bronze, brass, cast steel, stainless steel, ductile iron, cast iron, aluminum alloy, titanium alloy, ABS plastic, PVC plastic, a wide range can also be customized. It is suitable for sea water, cold fresh water, hot fresh water, air, steam, gas, lubricating oil and fuel oil piping system.

8.Specific Difference Between Us and Other Suppliers:

Comparison
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 accounts for 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, uniform material.	Use it with confidence, meet the needs of users, and the product has a long service life.
The valve cover is of poor manufacturing quality, uneven thickness, and uneven material.	The valve cover is prone to breakage, blisters, corrosion or aging problems.	Strictly in accordance with the standard processing, uniform thickness, uniform material.	The quality of the valve cover is good, it is not easy to generate air holes, and the product has a long service life.
Use iron, carbon steel to manufacture valves and repair scrap valves as shoddy valve products.	Such products generally have large errors in hardness and accuracy. It is easy to cause the shell to crack, and the phenomenon of running, running, dripping and leaking occurs, and in severe cases, the oil and gas pipelines will explode.	Manufacture new valves in strict accordance with customer material requirements.	Meet the hardness and precision requirements of standard valves,
The quality of flange manufacturing is poor, and there are problems such as cracks, pores, and insufficient thickness.	As a result, the valve is wear-resistant, the pressure bearing is poor, the valve is prone to quality problems, and the service life is short.	Materials are selected in strict accordance with national standards.	Ensure the quality of the valve and ensure the normal operation of the equipment.
Use ordinary round steel stem instead of stainless steel stem.	The performance of the substitute material is unstable, the ordinary round steel is processed, the valve stem is thin and there is no heat treatment, which leads to the deterioration of the valve quality.	Made of stainless steel, the diameter of the valve stem meets the design requirements, and it has undergone high temperature quenching and tempering heat treatment.	The valve is wear-resistant, has good pressure-bearing performance, and is not easy to be damaged.
The packing quality is poor, and there are defects such as loose packing, burrs, dryness, impurities, etc.	Lead to packing failure, easy to produce medium leakage, valve easy to malfunction.	High-quality fillers are selected, and there is no loose, impurity and other phenomena.	High safety factor, reasonable structure and long service life.
The hardness of the valve stem is too low, there are cracks, the valve stem is not round, and the valve stem is not bent straight.	The stem sealing surface is easily damaged and the valve service life is short.	Materials are selected according to standards and customer requirements.	The valve has good sealing and wear resistance, and it is not easy to cause leakage of the medium, and the valve has a longer service life.
To reduce cost, bronze spool is replaced with cast iron spool.	Cast iron valve core is easy to corrode and break.	The material is selected strictly according to the user's requirements.	The valve stem has high hardness, no cracks, good sealing performance, and long service life of the valve.
The manufacturer considers the cost and purchases unqualified standard bolts.	Leaving hidden dangers on the valve results in an accident.	According to customer requirements, use standard bolts.	High safety factor and reasonable structure.
Replace the copper stem with an iron-copper-plated stem.	The performance of the substitute material is unstable, resulting in a decrease in the quality of the valve.	The material is selected strictly according to the user's requirements.	Use it with confidence, reduce safety hazards and reduce the accident rate.
