Solution To The Problem Of Pneumatic Sanitary Diaphragm Valve Not Working

The solution to the failure of Sanitary Diaphragm Valve ventilation is as follows:

There are 8 pneumatic sanitary diaphragm valves of the same specification, with the same working conditions. After installation, the air source was connected, and the pressure was 4.5 kg. One of the pneumatic sanitary diaphragm valves did not move. Later, the air source pressure was increased to 8 kg, but the valve still did not move. The on-site technicians were puzzled.

The customer called the manufacturer for consultation. The manufacturer promptly dispatched technicians to the site to understand the situation and conduct tests. It was found that when the air source was input, no gas was discharged from the exhaust hole. The preliminary analysis was that the exhaust hole was blocked. Later, the cylinder head was opened and it was found that there was foreign matter in the cylinder of the sanitary diaphragm. It turned out that the on-site personnel accidentally pushed the dust cover into the cylinder piston cavity during installation, sealing the exhaust hole, resulting in the inability to discharge gas, the piston was blocked, and the valve did not move.

Finally, the foreign matter was removed and the sanitary diaphragm valve worked normally. Therefore, when installing a pneumatic sanitary diaphragm valve, it is necessary to strictly follow the requirements of the instruction manual to avoid unnecessary failures.
