Shanghai pneumatic butterfly valve injects inert gas and generates elastic function through the piston. This product does not need external power supply, rises and falls steadily, expands freely, and is widely used (lockable balloon valve can be placed at will). However, attention should be paid to the following points during installation:
1。 Pneumatic butterfly valve is a kind of high-pressure product, which is strictly and randomly analyzed, baked and crushed.
2。 Turn the piston rod of the pneumatic butterfly valve to the left. If you need to adjust the direction of the joint, you can only turn to the right.
3。 Operating ambient temperature: - 35C+70C (specific manufacturing temperature is 80 ℃)
4。 The installation connection point shall rotate flexibly without jamming.
5。 The selected size is reasonable, the stress is appropriate, and the stroke size of the piston rod should be 8mm.
