Wafer LT type butterfly valves with pneumatic actuator description

Wafer LT type butterfly valves with pneumatic actuator is the unversal type valve in the industrial valves wafer type butterfly valves with pneumatic actuator have a good characteristic in sealing and fixed in pipeline .due to the hole in the butterfly valves with pneumatic actuator ,wafer type butterfly valves with pneumatic actuator provide a esay method in installation and connection pipeline .so the pipeline can be very nice connection ,to control the water flow according to your requirements .

wafer type butterfly valves with pneumatic actuator features and advantages

1. Small in size and light in weight. Easy installation and mintenance. And it can be mounted wherever needed.

2. Simple and compact construction, 90 degrees on-off operation.

3. Mininzed operating torque, energy saving.

4. Flow curve tending to straight line. Excellent regulation performance.

5. Long service life. Standing the test of tens of thousands opening/closing operations.

6. Bubble-tight sealing with no leakage under the pressure test.

7. Wide selection of materials, applicable for various medium.

 Overall & Connection Dimensions & Weight of butterfly valves with pneumatic actuator

Note: DN50(2'')~600(24'') type pneumatic valve are suitable for the pressure grade of  PN1.0MPa and PN1.6Mpa separately. Two dimensions in one column have two connection dimnensions of PN1.0/PN1.6MPa pressure grade. For the connection dimensions of pipe flanges mounted to the gas valve. The upper flanges of  the pneumatic valves accomodates all types of  operaters: manual, womgear,electric and pneunatic actuators.

Installation & Maintenance of wafer type butterfly valves with pneumatic actuator

Installation Note

1. Prior to installation should check the valve specifications, pressure, temperature, corrosion resistance and meet the requirements. Should check the valve's part is damaged or loose.

2. This kind of  valve can be installed in any angle of pipe, and should be closed to install appropriate: welding pipe flanges should be blocking the valve seals, the plate to prevent particles and debris contusion close remove the valve cover, after welding, cleaning the valve sealing surface and pipe cavity, and then install the fixed valve.

3. Please note the valve direction.

4. The valve should be installed before the sealing surface (both ends of the sealing surface, the disc sealing surface, the seatsealing surface) thoroughly clean to remove dust and dirt.

5. Prior to installation should be empty test the valve, opening and closing should be flexible, opening and closing position is consitent with the pointer position.

6. Manual valve operation clockwise is off, counter-clockwise to open, the pointer indicates not allowed coupled with the power to open and close valve in place.

7. The valve to do the pressure test, not allowed to use the single flange installation pressure test, must be double flanged-mounted pressure test.

8. The fastening bolts should be symmetric alternating tightening are not allowed to turn separate fastening the valve.

9. Before imit screw leave the factory, has a good tune, not allowed to be easily adjusted. Configure the drive for electric, gas. Please read the supporting drive manual.

10. Before electric valve leave factory, opening and closing of the control mechanism has been fine, to prevent wrong direction when the power is turned on ,the user must first manually before the first powered open to semi open position, and then to move the switch, check indicates disk direction and the valve opening direction can be the same.

11. The valve opening and closing disorders should be identified and the reasons for repair and to exclude, prevent the switch valve after burner method, resulting in valve damage.

12. The valve failure really can not be ruled out, please let us know how will you do the product installation using the after-sale service.

Failures that Can Occur and Methods to Eliminate

Failure Phenomenon

Sealing Surface Leakage

Reason:         

1. Ring folder with debris.

2. Valve's sealed closed position consistent errors.

3. Export equipped with flange bolts are uneven force or compression.

4. The pressure test of the valve is incorrect.

Elimination: 

1. Elimination of impurities, cleaning the  valve cavity.

2. Adjust the worm gear or  electric actuator, such as implementing agencies limit screw is reached the pressure reducing valve closed position is correct.

3. Check mating flange plane and bolt champing force should be evenly pressed.

4. Put pressure on the direction of the arrow.

Valve at Both Ends of the Surface Leak

Reason:      

1. On both sides of gasket failure. 

2. Uneven cargo pipe flange clamping force is not pressed.

Elimination:   

1. Replace the gasket.

2. The compression flange bolts (evenly).

Method of Operation

1. Manual valves: handle out of the pipe into a parallel position, the valve in the open position,     90 centigrade angle, the valve in the closed position. Clockwise rotation of the handle is off the valves, and counterclockwise rotation of the handle to open the valve.

2. The valve of the worm gear: according to the part of the valve is installed indicating device identification, clockwise rotation of the handwheel off valve counterclockwise rotation of the handwheel to open the pressure reducing valve.

3. Pneumatic, electric, electro-hydraulic  valve linkage operation, in accordance with the drive manual.
