The Difference Between Pneumatic Sanitary Valves And Manual Sanitary Valves

There are significant differences between Sanitary Valve and manual sanitary valves in multiple aspects.

Firstly, from the perspective of driving mode, pneumatic sanitary valves are driven to open and close by pneumatic actuators, which are usually powered by compressed air or other gases to achieve automatic control of the valve. However, manual sanitary valves rely on manual operation, such as handles or handwheels, and their adjustment accuracy is affected by the operator's technical level and experience.

Secondly, in terms of control methods and applicable scenarios, pneumatic sanitary valves can achieve automatic monitoring and adjustment in central control rooms or computers, greatly improving production efficiency and control accuracy. They are suitable for scenarios with medium to large flow rates, high pressures, and frequent control and adjustment needs, such as large-scale industrial fields such as chemical, petroleum, and natural gas. Manual sanitary valves are more suitable for scenarios with low flow, low pressure, and no need for frequent adjustment, such as laboratories or small production lines.

In addition, the maintenance and upkeep requirements of the two are also different. Due to the lack of complex pneumatic actuators and other components, manual sanitary valves are relatively easy to maintain, generally only requiring cleanliness and lubrication. The maintenance of pneumatic sanitary valves may involve more complex equipment and procedures.

Finally, from the perspective of hygiene standards, sanitary valves refer to valves that meet hygiene standards such as medicine or food. The valve body should meet the hygiene standards of stainless steel, and all parts in contact with the medium should be mirror polished, with polishing and cleanliness in accordance with relevant hygiene standards. Both pneumatic and manual sanitary valves need to meet these basic hygiene requirements.

There are significant differences between pneumatic sanitary valves and manual sanitary valves in terms of driving mode, control mode, applicable scenarios, maintenance and upkeep requirements. The choice of valve mainly depends on the specific application scenario and requirements.
