Q41f Stainless SteelFlangethe Working Principle of Ball Valve Is to Rotate the Valve Stem to Make the Valve Unblocked Or Blocked. Ball Valve Switch Is Light, Small in Size, Can Be Made into a Large Diameter, Reliable Sealing, Simple Structure, Convenient Maintenance, Sealing Surface and Spherical Surface Are Often Closed, Not Easy to Be Eroded by Medium, it Is Widely Used in Various Industries.
Advantages:Folding
1. the Fluid Resistance Is Small, and Its Resistance Coefficient Is Equal to the Pipe Section of the Same Length.
2. Simple Structure, Small Volume and Light Weight.
3. Close and Reliable. at Present, Plastic Is Widely Used in the Sealing Surface Material of Ball Valve, Which Has Good Sealing Performance and Has Been Widely Used in Vacuum System.
4. Easy Operation, Quick Opening and Closing, fromFully OpenIt Only Needs to Rotate 90 ° to Fully Close, Which Is Convenient for Remote Control.
5. Easy Maintenance, Simple Structure of Ball Valve, Sealing Ring Is Generally Movable, Disassembly and Replacement Are More Convenient.
6. When Fully Open Or Fully Closed, the Sealing Surface of the Ball and Valve Seat Is Isolated from the Medium, and When the Medium Passes through, It Will Not Cause Erosion of the Sealing Surface of the Valve.
7. Wide Range of Application, Diameter from Small to a Few Millimeters, Large to a Few Meters, from High Vacuum to High Pressure Can Be Applied.
Ball Valve Has Been Widely Used in Petroleum, Chemical Industry,Power Generation, Papermaking, Atomic Energy, Aviation, Rockets and Other Departments, as Well as People's Daily Life.
ManualFolding
1. Scope: This Manual Is Applicable to the Electric (Or Pneumatic) Ball Valve at the Flange Connection End.
2. Composition: It Consists of Electric (Or Pneumatic) Actuator (20) and Valve Body Part of Ball Valve, Which Is Connected by Bracket (18) and Connecting Shaft (17).
3. Usage Restrictions
Temperature and Pressure LimitsFolding
1. the Nameplate Shows the Maximum Operating Pressure Allowed by the Ball Valve at the Maximum and Minimum Operating Temperatures.
2. Use Ptfe Or RtfeValve seatandSeal, the Operating Temperature Should Be between-290c and 2000c. the Operating Temperature of Other Types of Valve Seats and Seals Shall Be Checked by Ki Factory.
3. the Nominal Pressure Level (Pn) of the Valve Can Indicate the Maximum Working Pressure of the Valve under Normal Temperature. (for Example, Pn4.0 Indicates That the Maximum Working Pressure When the Operating Temperature Is-290c ~ 380c Is 40 Bar(4.0Mpa).).
4. for the Precautions of Electric Or Pneumatic Actuator, Please Refer to Its Corresponding Instructions.
Installation InstructionsFolding
1) Remove the Protective Cover on Both Sides of the Flange End and Rinse and Clean the Valve When It Is Completely Open.
2) before Installation, the Whole Machine Should Be Tested According to the Specified Signal (Electricity Or Gas) (to Prevent the Use Performance from Being Affected by Vibration Caused by Transportation), after Passing the Qualification, It Can Be Installed Online (the Wiring Is Based on the Circuit Diagram of the Electric Actuator).
3) before Preparing to Connect with the Pipeline, Wash and Remove the Remaining Impurities in the Pipeline (These Substances May Damage the Valve Seat and Ball).
4) during Installation, Please Do Not Use the Actuator Part of the Valve as the Lifting Point to Avoid Damaging the Actuator and Accessories..
5). This Type of Valve Should Be Installed in the Horizontal Or Vertical Direction of the Pipeline.
6), the Pipeline near the Installation Point Should Not Have the Phenomenon of Drooping Or Bearing External Force, and the Pipeline Bracket Or Support Can Be Used to Eliminate the Deviation of the Pipeline.
7). after Connecting with the Pipe, Please Cross-Lock the Flange Connecting Bolts with the Specified Torque.
Operation and UsageFolding
1) before Operation, Make Sure That the Pipeline and Valve Have Been Washed.
2) the Operation of the Valve Drives the Valve Stem to Rotate According to the Input Signal of the Actuator. When the Forward Rotation Is 1/4 Turn (900), the Valve Is Closed. When Rotating 1/4 Turns (900) in Reverse Direction, the Valve Opens.
3) When the Direction Indicating Arrow of the Actuator Is Parallel to the Pipeline, the Valve Is Open; When the Direction Indicating Arrow Is Perpendicular to the Pipeline, the Valve Is Closed.
MaintenanceFolding
Having a Long Service Life and Maintenance-Free Period Will Depend on the following Factors: Normal Working Conditions, Maintaining a Harmonious Temperature/Pressure Ratio, and Reasonable Corrosion Data
Note: ● When the Ball Valve Is Closed, Pressure Fluid Still Exists inside the Valve Body.
● before Maintenance, Relieve the Pipeline Pressure and Put the Valve in the Open Position.
● Disconnect the Power Supply Or Air Source before Maintenance
● before Maintenance, Separate the Actuator from the Bracket.
Classification and CharacteristicsFolding
Ball Valves Are Divided into O-Type Ball Valves and V-Type Ball Valves. O-Type Ball Valve Adopts Floating Structure, the Ball Core Is Precision Casting, the Surface Is Electroplating Hard Chrome Processed, the Valve Seat Is Made of Reinforced PTFE Material, the Flow Port Is the Same as the Pipe Diameter, the Circulation Capacity Is Great, the Flow Resistance Is Very Small, no Leakage When Closed, Generally Used for Switch Valve, Especially Suitable for High Viscosity, Fiber and Granular Media; V-Shaped Ball Valve Adopts Fixed Structure, with V-Shaped Incision on the Ball Core, Which Can Realize Proportional Adjustment, the Traffic Characteristic Is an Approximate Equal Percentage.
Pneumatic Or Electric Ball Valves Can Be Selected According to Different Process Equipment to Form Pneumatic Ball Valves and Electric Ball Valves Respectively. If Pneumatic Ball Valves Want to Realize Proportional Adjustment, They Must Be Equipped with Valve Locators, if the Electric Ball Valve Is to Realize Proportional Adjustment, the Electronic Electric Actuator Or Servo Amplifier Shall Be Selected.
From the Material, It Can Be Divided into: Carbon Steel Ball Valve, Stainless Steel 304 Ball Valve, 316 Ball Valve and Copper Ball Valve
Application, Can Be Divided into: High Pressure Ball Valve and Low Pressure Ball Valve
High Pressure Ball Valve: Mainly Used in Oil, Natural Gas, Hydraulic Oil, Construction Machinery and Other Industries
Low Pressure Ball Valve: Mainly Used in Corrosive Pipelines Such as Medium Water!
