Q671FPm10-pn16 pneumatic ultra-thin ball valve pm10-pn16 is one of the pneumatic ball valves. It is a new generation of ultra short flange distance ball valve. The ball core channel shapes are rectangular, V-shaped and O-shaped. Pneumatic valve has the characteristics of compact structure, small volume, light weight and convenient installation. Valve can be widely used in petroleum, chemical industry, metallurgy, power station, light industry and other fields to automatically adjust or cut off oil, water, gas, pulp or fibrous fluid. The pneumatic ball valve is composed of pneumatic double piston rack and pinion actuator and ultra short flange distance ball valve. The valve body is the same as that of 1 electric ball valve. Pneumatic piston actuator is divided into spring type and non spring type. When the valve is fully open or closed under fault, it is required to be equipped with spring type (relying on the recovery tension reset of spring), and when it is required to maintain the position under fault, it is equipped with non spring type. It is mainly composed of cylinder block, spring, piston, piston rod, front and rear cylinder head, rack, output shaft and other parts. For two position on-off valve, solenoid valve and travel switch are required; for comparison, positioner is required.

Preparation before installation of pneumatic ball valve:
1. Ensure that the installation position of the pneumatic pipeline ball valve is in the coaxial position, and the two flanges on the pipeline shall be kept parallel to confirm that the pipeline can bear the weight of the pneumatic pipeline ball valve. If it is found that the pipeline can not bear the weight of the pneumatic pipeline ball valve, the corresponding support shall be provided for the pipeline before installation.
2. To confirm whether there are impurities and welding slag in the pipeline, the pipeline must be blown clean.
3. Check the name plate of the pneumatic pipeline ball valve, and operate the pneumatic pipeline ball valve fully open and closed for several times to confirm that the valve can work normally, and then check all details of the valve once again to ensure that the valve is intact.
4. Remove the protective covers at both ends of the valve, check whether the valve body is clean, and clean the inner cavity of the valve body. Since the sealing surface of the ball valve in the pneumatic pipeline is ball shaped, even small impurities may cause damage to the sealing surface.
Installation of pneumatic pipeline ball valve:
1. Any section of the pneumatic pipeline ball valve can be installed at the upstream end, and the handle pneumatic pipeline ball valve can be installed at any position of the pipeline. If the pneumatic pipeline ball valve with actuator (such as gearbox and electro pneumatic actuator) is equipped, it must be vertically installed, and the inlet and outlet of the valve shall be in horizontal position.
2. The sealing gasket shall be installed between the flange of the ball valve and the flange of the pipeline according to the design requirements of the pipeline.
3. The bolts on the flange shall be tightened symmetrically, successively and evenly.
4. If pneumatic and electric actuators are adopted for pneumatic pipeline ball valve, the installation of air source and power supply shall be completed according to the manual.
Inspection after installation of pneumatic pipeline ball valve:
1. After the installation, start the pneumatic pipeline ball valve to open and close several times. The action should be flexible and the force should be uniform. The pneumatic pipeline ball valve should work normally.
2. According to the design requirements of the pipeline pressure, the sealing performance of the joint surface between the pneumatic pipeline ball valve and the pipe flange is tested after pressurization.
