Bronze Ball Valve

Bronze Ball Valve

Application

JIS Ball Valve is used for all kinds of ships and used for preventing refluence in liquid medium piping.

Configuration Options

Name of Parts	Material	Advantages/Disadvantages
Valve Body	Bronze	Pressure resistance, wear resistance, and toughness are higher than those of brass. Bronze has a certain delay in the rusting time of the valve. more expensive than brass
	Brass	Brass has strong wear resistance. It has high strength, high hardness and strong chemical resistance. The mechanical properties of cutting are also outstanding
Valve Bonnet	Bronze	Seawater corrosion resistance, a little more expensive than cast steel and cast iron
	Brass	Brass has low pressure resistance and is easy to rust. The price is lower than bronze.
Valve Sphere	Bronze	Bronze has excellent low temperature resistance, the price is a little more expensive than stainless steel, and the seawater resistance of bronze is better than that of stainless steel
	Brass	Brass has good mechanical properties and wear resistance
Valve Stem	Bronze	Bronze has excellent low temperature resistance, good corrosion resistance, wear resistance, casting and excellent mechanical properties
	Brass	The price is cheap, the strength and hardness are high and the plasticity is poor, but it can still withstand pressure processing well in the hot state, and the corrosion resistance is average.
Valve Seat	PTFE	It has the characteristics of acid and alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is extremely low

Specific Difference 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 omit raw materials and reduce costs, it is expensive, resulting in thinning of the valve body	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	To meet the needs of users, long service life of products
Poor manufacturing quality of valve cover, uneven thickness, uneven material	Bonnets are 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.
Refurbished valve old valve masquerading as new valve	Refurbished valves are 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.	Select materials in strict accordance with national standards	Ensure the quality of the valve and ensure the normal operation of the equipment.
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.	Strictly select materials according to user requirements	The valve is wear-resistant, has good pressure-bearing performance, and is not easy to be damaged.
The valve stem hardness is too low, there are cracks, the valve stem is not round, and the valve stem is not bent and straight.	The stem sealing surface is easily damaged and the valve service life is short.	Materials are selected according to standards and customer requirements.	High safety factor, reasonable structure, long product life
