The pneumatic handwheel tank bottom valve is a highly clean, hygienic and non-retention diaphragm valve, which is mainly used in industrial fields such as biopharmaceuticals or food processing. It is installed at the bottom of the container equipment to empty the material inside the container and ensure that it does not become trapped inside the valve chamber. When a cleaning or opening task is required, the stem can be driven upward by manually rotating the handwheel or driving the pneumatic control actuator, so that the valve forms a conduction state. In addition, the ZMQF/ZSQF series pneumatic kettle bottom valve adopts an integrated DC structure, and the valve body is a streamlined unobstructed flow channel, which ensures smooth wear resistance, small flow resistance, and no dead ends.
A pneumatic handwheel tank bottom valve is a specialized type of
valve primarily used in industrial sectors such as biopharmaceuticals or
food processing. This valve is installed at the bottom of the container
equipment and is responsible for draining the material inside the
container to ensure that the material does not remain inside the valve.
In terms of working principle, when cleaning or opening tasks are required, the valve stem can be driven upward by manually rotating the handwheel or driving the pneumatic control actuator, so that the valve forms a conduction state. This design can effectively eliminate the residue phenomenon of process media usually at the outlet of the container, and realize the function of emptying and draining.
It is worth mentioning that the bottom valves (including pneumatic handwheel tank bottom valves) are welded or flanged to the bottom of the reactor or storage tank and other vessels with the help of the bottom flange (flange) of the valve. Because its valve body is a streamlined unobstructed flow channel, it ensures smooth wear resistance, small flow resistance, and no dead ends.
The advantages of pneumatic handwheel tank bottom valves include:
It can realize proportional adjustment to meet the needs of various working conditions.
The 35-degree installation orientation is adopted, so that the material discharge has a self-cleaning function, and the space is more convenient for equipment maintenance.
The streamlined unobstructed flow channel design in the valve
ensures smooth wear resistance, small flow resistance, and no dead ends.
However, there are some disadvantages to this valve:
The cost is relatively high due to the need for pneumatic actuators and control systems.
Maintenance costs are also higher, as it requires regular maintenance and overhaul.
The pneumatic drive mode makes it highly dependent on the air source.
