DN15~DN100 Socket Threaded 3 Way UPVC Pneumatic Ball Valve
DN15~DN100 Socket Threaded UPVC Pneumatic Ball Valve
| Valve type | Recommend install condition |
| Clip on butterfly valve | actuator rate torgue ≥ 2 times valve max torque |
| Flange butterfly | actuator rate torque ≥1.7 times valve max torque |
| Metal ball valve | actuator rate torque ≥1.7 times valve max torque |
| Plastic ball valve | actuator rate torque ≥1.7 times valve max torque |
1.lf the ball valve ls out of operation for a long time, and the torque value of first on or off ls the max torque.
2. When installing direct mount model valve, the hole deep < 15mm. it requires cutting if the output shaft is longer than 15mm.
3. Pls pay attention to the following items if you install the bracket and coupling by yourself.
A) The intensity of bracket should meet the using requiremerts: the bracket twisting extent<0.2mm in the process of on or off.
B) The parallelism of bracket <0.5mm
3) When processing the shaft hole at both end of the coupling, it is necessary to ensure the accuracy and concentricity. The purpose is to make sure the mechanical hysteresis < 10*, otherwise it will cause the actuator unable to work.
4. Screw should be installed spring washer, flat washer, and we suggest you daub some glue cement around the screw in
case of screw loosening.
5. After installation, user should switch the valve on and off one time with handle device first.Modifying the valve after make sure it works well.
