Pneumatic butterfly valve installation requirements
read the instructions before installing must consult speaking correct installation, in order to ensure that its rigorous work accurately.
1, before installation check pneumatic butterfly valve no missing parts, model is correct, check the valve body without sundry, solenoid valve and the muffler internal nonblocking
2, the valve and cylinder are placed in the closed position.
3, will hit the valve cylinder, ( The installation direction parallel to the valve body or vertical) , see if the screw hole for again, won't have too big deviation, if you have a little deviation, cylinder block turning point, then tighten the screw.
4, after the installation of debugging pneumatic butterfly valve ( Under normal circumstances gas supply pressure is zero. 4 to 0. 6MPa） Debugging operation manual operation with solenoid valve opening and closing ( The solenoid valve coil manual operation shall be effective after losing electricity And observe the pneumatic butterfly valve opening and closing. If in the process of debugging operation found some difficulty in opening and closing process of the initial valve, after normal, you may need to dispatch cylinder stroke ( The ends of cylinder stroke adjusting screw to adjust a bit at the same time, adjust the need to run the valve in the open position, and then dispatch air off again) Until the valve opening and closing action smooth and closed without any leakage. Also it is important to note that the adjustable type silencer can adjust the valve opening and closing speed, but not too small, otherwise may cause the valve is not action.
5, have to send before installation should keep dry, not in open air
6, the butterfly valve to check the pipeline before installation, make sure that the pipe welding slag and other foreign body
7, manual type butterfly valve body resistance is moderate, butterfly valve torque matching with the selected actuator torque.
8, butterfly valve connected with the flange specifications correctly, pipe flanges are in conformity with standard butterfly valve flange to the clamp. It is recommended to use special butterfly valve flange, flat welding flange shall be used.
9, verify the flange welding, not welding flange butterfly valve after the installation, so as not to burn rubber parts.
10, the pipe flange are going to have to pack good, and with butterfly valve in the.
11 and install all flange bolts, with the hand tight, just, will confirm the butterfly valve with flange and with the opening and closing butterfly valve, to ensure that the opening and closing flexible.
12, open the valve fully, tighten bolts, using a wrench, in accordance with the diagonal order without washers, never will bolt screw tight, in order to prevent causing serious deformation, valve ring opening and closing torque is too big.
