Valve Shaft Is An Important Part Of The Valve, Which Is Used For Transmission, Connecting The Actuator Or Handle, And Directly Driving The Valve Core To Move Or Rotate Below To Realize The Valve Switch Or Regulation.
Function: Realize Valve Switch Or Regulation
Material: Stainless Steel
Performance Requirements: Adequate Strength, Good Impact Toughness
In The Process Of Valve Opening And Closing, The Valve Shaft Is Not Only a Moving Part, a Stress Part, But Also a Sealing Part. At The Same Time, It Is Impacted And Corroded By The Medium, And It Also Rubs Against The Filler.
Therefore, When Choosing The Material Of The Valve Shaft, We Must Ensure That It Has Sufficient Strength, Good Impact Toughness, Abrasion Resistance And Corrosion Resistance At The Specified Temperature. The Valve Shaft Is a Fragile Part, And The Mechanical And Heat Treatment Properties Of The Material Should Be Paid Attention To When Selecting The Valve Shaft.
The Main Features Of This CNC Machining Stainless Steel Valve Shaft Are As Follows:
1, CNC Machining Centers Are Needed For Centralized Processing, High Precision, Fast Production, High Efficiency, And Mass Production. Compared With The Simple Cast Valve Shaft, The Performance Is Greatly Improved.
2, Stainless Steel Material Is Its Raw Material, Corrosion Resistance, Acid Resistance, Alkali Resistance, Seawater Resistance.
Generally, 2Cr13, 3Cr13, 1Cr17Ni2, 1Cr18Ni12Mo2Ti And Other Materials Are Selected.
2Cr13 And 3Cr13 Stainless Steels Are Suitable For Water, Steam And Weak Corrosive Media With Nominal Pressure Less Than Or Equal To 32MPa And Temperature Less Than Or Equal To 450 Degrees. They Can Be Strengthened By Chromium Plating And High Frequency Quenching.
1Cr17Ni2 Stainless Steel Valve, Low Temperature Valve, Corrosion Resistant Medium.
1Cr18Ni9Ti And 1Cr18Ni12Mo2Ti Stainless Steel Are Used In High Temperature Valves With Nominal Pressure Less Than 6.4mpa And Temperature Less Than 600 Degrees, Stainless Steel Valves With Temperature Less Than – 100 Degrees And Low Temperature Valves.
1Cr18Ni9Ti Can Resist Corrosive Medium Such As Nitric Acid.
1Cr18Ni12Mo2Ti Can Resist Corrosive Media Such As Acetic Acid.
When 1Cr18Ni9Ti And 1Cr18Ni12Mo2Ti Are Used In High Temperature Valves, Nitrogen Treatment Can Be Used To Improve The Scratch Resistance.
