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.

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
