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
	Cast Steel	The price is higher than cast iron and lower than bronze.  It has high mechanical strength and toughness.  With heat resistance, corrosion resistance, wear resistance and other special properties.
	Cast Iron	The carbon content of cast iron is relatively high, and its performance is relatively brittle; the tensile performance is relatively poor; the casting performance is relatively good, and the casting method can be used to process parts with relatively complex shapes.
	Stainless Steel	Resistant to weak corrosive media such as air, steam, and water, and is rust-resistant
	Forged Steel	It has the advantages of good ductility and low cost
Valve Bonnet	Bronze	Seawater corrosion resistance, a little more expensive than cast steel and cast iron
	Cast Steel	The price is higher than cast iron and lower than bronze. Has high mechanical strength and toughness. It has special properties such as heat resistance, corrosion resistance and wear resistance.
	Cast Iron	Not resistant to corrosion and cost less than bronze and cast steel
Valve Disc	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
	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.
Valve Stem	Stainless Steel 304	SS 304 has good processing performance and high toughness
	Stainless Steel 316	SS 316 has better corrosion resistance and high temperature strength
Hand Wheel	Cast Iron	Cost less than bronze and cast steel

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
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, it will cause the explosion of the oil and gas pipelines.	According to customer requirements to manufacture new valves, never shoddy.	Meet the hardness and precision requirements of standard valves, Ensure the quality of the valve and ensure the normal operation of the equipment.
Flange manufacturing quality is poor, there are cracks, pores, thickness is not enough and other problems	Lead to poor wear resistance of the valve, the valve is prone to quality problems, short service life.	Material selection in strict accordance with national standards	Valve wear resistance, pressure performance is good, not easy to damage
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
The manufacturer considers the cost and purchases unqualified standard bolts	Leaving hidden dangers on the valve can easily lead to accidents.	According to customer requirements, use standard bolts.	Use it with confidence, reduce safety hazards and reduce the accident rate.
The quality of flange manufacturing is poor, and there are problems such as cracks, pores, and insufficient thickness	the valve is not 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	The valve is wear-resistant, has good pressure-bearing performance, and is not easy to be damaged.
