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. The price is higher than brass |
|
Brass |
Brass has low pressure resistance and is easy to rust. The price is lower than bronze. |
|
|
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. |
|
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 |
|
|
Handle |
Bronze |
It has good high temperature corrosion resistance and oxidation resistance. It has good corrosion resistance in the atmosphere, fresh water and sea water, and the machinability is acceptable. It can be welded and not easy to braze. |
|
Cast Iron |
Cost less than bronze |

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, |
|
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 |
Specifications:
Features:
Non-sticky: Almost all substances do not adhere to the Teflon film. Very thin films also show good non-stick properties.
Heat resistance: Teflon coating film has excellent heat resistance and low temperature resistance.It can withstand high temperature to 300°C in a short time
Sliding property: Teflon coating has a low coefficient of friction.The friction coefficient changes when the load is sliding, but the value is only between 0.05-0.15.
Moisture resistance: The surface of the Teflon film is free of water and oil, and it is not easy to be stained with solution during production operations.
Wear resistance: It has excellent wear resistance under high load.
