List

JIS F7480 Lug Type Butterfly Valve

Configuration Options:

Name of Parts	Material	Advantages/Disadvantages
Valve Body	Bronze	Bronze has the characteristics of low melting point, high hardness, strong plasticity, wear resistance, corrosion resistance, bright color, etc.
	Cast iron	The tensile strength, ductility and toughness of cast iron are lower than those of carbon steel. Lower price than bronze and stainless steel
	Carbon Steel	Low strength, low hardness, good plasticity and good weldability.
	Stainless Steel	High corrosion resistance makes it usable in harsh environments. It is fire and heat resistant, resists scaling and maintains strength at high temperatures.
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.
	Aluminum Bronze	It has high strength and good wear resistance. It is used for high-strength screws, nuts, copper sleeves, sealing rings, etc., and wear-resistant parts. The most prominent feature is its good wear resistance.
Valve Seat	NBR	Applicable medium 0-80℃ oil class
	EPDM	Suitable medium -20-120℃ water, steam, etc
	PTFE	Applicable to corrosive media below 200℃
	Hard alloy	Suitable for high temperature and high pressure environment
Valve Stem	Stainless Steel	Key advantages include its high corrosion resistance, making it usable in harsh environments. It is fire and heat resistant, resists scaling and maintains strength at high temperatures.
Handle	Cast Iron	Cost less than bronze

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-built, the valve body wall thickness does not follow the standard processing	Uneven thickness and material, it’s easy to damage the valve body.	Strictly in accordance with the standard processing	Customer use rest assured, to meet user needs, the product has long service life.
Use recovered waste valves as good valves.	It is easy to cause the shell to crack, and in severe cases, the oil and gas pipelines will explode.	Strictly in accordance with customer material requirements to manufacture new valves.	Meet the hardness and precision requirements of standard valves, Ensure the valve quality, ensure the normal operation of 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
Bronze valve disc was replaced with cast iron valve disc in order to reduce costs.	Cast iron valve disc is prone to corrosion and damage	Material selection in strict accordance with national standards	High safety factor, reasonable structure
