Cast Iron Butterfly Valve

Cast Iron Butterfly Valve

Introduction:

The valve is mainly used to cut off the fluid it also can be designed to have the function of adjusting and cutting off the fluid. Users can choose pin or without pin type according to different requirements

Configuration Options:

Name of Parts	Material	Advantages/Disadvantages
Valve Body	Grey cast iron	The most common material in butterfly valves, mainly used in water systems, is easily corroded, has a short service life and is cheap.
	Ductile cast iron	The performance of the butterfly valve is comparable to that of carbon steel. It is generally used in water system pipes, and it is also a very widely used material in water systems at present.
	Carbon steel	It can also be used in water systems, but it is not used much. Carbon steel butterfly valves have high temperature and pressure resistance. Generally, hard-sealed butterfly valves are mostly made of carbon steel.
	Stainless Steel	It has good anti-corrosion and anti-corrosion properties, and is also mostly used in pipelines that need anti-corrosion and anti-rust, and the cost is relatively high.
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 Disc	Bronze	Bronze has excellent low temperature resistance, good corrosion resistance, wear resistance, casting and excellent mechanical properties
Valve Seat	EPDM	Suitable medium -20-120℃ water, steam, etc
	NBR	Applicable medium 0-80℃ oil class
	PTFE	Applicable to corrosive media below 200℃
	Hard alloy	Suitable for high temperature and high pressure environment
Hand Wheel	Cast Iron	Cost less than bronze and cast steel

Specific differences 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	Consequence
Jerry-build, the wall thickness of the valve body is not processed according to the standard	Uneven thickness, and material, the valve body is easy to be damaged, and the service life is short.	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
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.
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.
