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	Good wear resistance and corrosion resistance, longer durability than ordinary steel; easy plastic processing; simple and convenient maintenance; good welding performance
Valve Seat	Bronze	Good castability, wear and corrosion resistance and stable chemical properties
Valve Seat	Stainless Steel	Stainless steel will not produce corrosion, pitting, rust or wear, with corrosion resistance, enhanced strength, steel deformation is not easy to break and environmental protection performance, not easy to rust.
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
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.
Valve Stem	Stainless Steel	Stainless steel has the characteristics of corrosion resistance, high temperature oxidation resistance, high strength, and stable steel plate quality.
Valve Stem	Bronze	Low melting point, high hardness, easy to cast
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
Jerry-build, the wall thickness of the valve body is not processed according to the standard	Uneven thickness, the valve body is easy to be damaged, and the service life is short.	Strictly in accordance with the standard processing, uniform thickness	Use with confidence, meet user needs, and the product has a long service life
In order to reduce cost, bronze valve core is replaced with cast iron valve core,	Cast iron valve core is easy to corrode and break	Strictly select materials according to user requirements	High safety factor and reasonable structure
Manufacturers save costs and purchase unqualified standard bolts	The valve leaves a safety hazard, which is easy to cause an accident	According to customer requirements, use standard bolts.	Use it with confidence, reduce safety hazards and reduce the accident rate.
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.	High safety factor, reasonable structure, long product life
Use iron, carbon steel to make valves and repair scrap valves as brand new ones.	Such products generally have large errors in hardness and accuracy, which are prone to accidents.	Manufacture brand new valves in strict accordance with customer material requirements, never shoddy.	Meet the hardness and precision requirements of standard valves,
