1.Pneumatic ball valve Matters needing attention
This operation manual is used to help users install and maintain correctly, and ensure the
safe and trouble-free operation of the valve.
Before installation, please do not remove the valve from the package.
The valve must be stored in a dry and dust-free environment and protected from light.
If the valve can be stored correctly, no additional preservation measures are required.
The installation, disassembly and maintenance of the valve must be performed by trained
Before disassembling the valve, you must first stop the valve from running and isolate it
from the system, and make sure that there is no pressure in the valve.
Valves designed according to the special requirements of users can only be used under
the conditions specified in the design.
2. Pneumatic ball valve Application areas
The ball valve can serve as the isolation and adjustment function of the key parts of the
system. It is widely used in pipelines in almost all industrial fields. The applicable media
include liquids, gases and granular materials.
The main application areas are:
-chemical and petrochemical industry
– Marine Engineering
– gas supply system
– food industry
– Wastewater treatment and water supply and drainage engineering
– Cold storage and HVAC system
– power plants and heating plants
3.Pneumatic ball valve Installation
The pipeline before and after the ball valve is ready. The front and rear pipes should be
coaxial, and the sealing surfaces of the two flanges should be parallel. The pipe should be
able to bear the weight of the ball valve, otherwise the pipe must be equipped with proper
support. Clean the pipelines before and after the valve to remove the oil, welding slag and
all other impurities in the pipeline. Check the mark of the ball valve to find out that the ball
valve is intact. Fully open and close the valve several times to verify that it is working
properly. Remove the protective parts on the connecting flanges at both ends of the ball
valve. Check the valve hole to remove possible dirt, and then clean the valve hole. Even
small foreign matter between the valve seat and the ball may damage the seat sealing
surface. Install the valve in the pipeline. Either end of the valve can be installed at the
upstream end. The valve driven by the handle can be installed at any position on the
pipeline. But the ball valve with gear box or pneumatic driver should be installed upright,
that is, installed on the horizontal pipeline, and the driving device is above the pipeline.
Install a gasket between the valve flange and the pipeline flange according to the pipeline
4.Pneumatic ball valve Operation
Before starting, check whether the valve is installed correctly (installation position, flange
hole), and check whether the valve core and valve seat sealing ring are suitable for the
medium used. POV valve can adjust the control medium arbitrarily between 15° and 70°.
Please be careful not to operate the valve in cavitation conditions.
