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 low pressure resistance and is easy to rust. The price is lower than bronze.
Valve Bonnet	Bronze	Good castability, wear and corrosion resistance and stable chemical properties
	Brass	Brass is the cheapest, with high strength, hardness and poor plasticity, but it can still withstand pressure processing well in hot state, and its corrosion resistance is average.
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
	Brass	Good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy fiber welding and welding, corrosion resistance, but easy to produce corrosion cracking, and cheap
Gasket	Non-asbestos	It has very good water tightness, air tightness, and fuel tightness, good mechanical properties, oil resistance, temperature resistance, and pressure resistance.

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
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.
In order to reduce cost, bronze valve disc is replaced with cast iron valve core,	Cast iron valve disc is easy to corrode and break	Strictly select materials according to user requirements	High safety factor and reasonable structure
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
Jerry-built, 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
