How to add lubricating oil for several wire system of electric hydraulic butterfly valve power supply? 2、 Installation of pneumatic ball valve
Any section of the pneumatic ball valve can be installed at the upstream end, and the handle ball valve can be installed at any position of the pipeline. If the ball valve is equipped with an actuator (such as a gearbox, an electro pneumatic actuator), it must be installed vertically, and the inlet and outlet of the valve are in a horizontal position.
The sealing gasket shall be installed between the pneumatic ball valve flange and the pipeline flange according to the pipeline design requirements.
The bolts on the flange shall be tightened symmetrically, step by step and evenly.
If the ball valve adopts pneumatic, electric and other actuators, complete the installation of air source and power supply according to the instructions.
、 (2) The electric switch butterfly valve belongs to the field instrument, and the suitable working temperature should be in the range of - 25-60 degrees, and the relative humidity should not exceed 95%. If it is installed at high temperature or in the open air, cooling and waterproof measures should be taken. If there is a source, shockproof measures should be taken, or it can be far away from the source.
