Features and production process of sanitary tank bottom diaphragm valve.

Features and production process of sanitary tank bottom diaphragm valve

1 No retention: the unique diaphragm design ensures that the material is completely emptied when the valve is closed, avoiding material residue and cross-contamination.
2 Highly clean: the surface of the valve has been specially treated, smooth without dead space, easy to clean and disinfect.
3 A variety of actuator selection: pneumatic, electric and other actuators can be selected according to actual needs to meet the requirements of different pressure levels.
4 Polishing treatment: the surface of the valve body can be mechanically polished or electropolished according to customers' requirements to improve the aesthetics and corrosion resistance of the valve.
5 sanitary design: in line with the hygiene standards of the biopharmaceutical and food processing industries, to ensure that the product is pure and pollution-free
6 In short, sanitary stainless steel tank bottom diaphragm valve is a kind of sanitary valve suitable for bio-pharmaceutical and food processing industries, etc. It has the features of no stagnation, high degree of cleanliness, a variety of actuator choices and polished treatment.

Precision diaphragm manufacturing and assembly process. This part of the process is directly related to the sealing, corrosion resistance and service life of the valve, and is the most important part of the process.

First of all, the choice of diaphragm material is extremely critical, need to meet the food-grade or pharmaceutical-grade standards of polymer materials, such as reinforced PTFE (polytetrafluoroethylene) or EPDM (EPDM), these materials not only have a good chemical stability, resistance to a variety of media, but also has excellent elasticity and abrasion resistance, to ensure that the sealing effect of the long-term use.

The next step is the diaphragm moulding process, which mostly adopts moulding or injection moulding technology. Through precisely controlled temperature and pressure, the material is uniformly distributed in the mould to form shapes and sizes that meet the design requirements. After moulding, the diaphragm is subject to strict dimensional inspection and surface treatment to ensure that it is free of defects and air holes and to improve the overall quality.

During the assembly stage, the diaphragm is carefully placed inside the valve body, where it is closely fitted to the valve seat and drive mechanism. This process requires extremely high assembly precision, and any slight deviation may affect the sealing performance of the valve. Therefore, with the help of advanced jigs and fixtures and testing equipment, workers need to carry out several debugging and calibration until the optimal assembly state is reached.

Finally, the whole valve also needs to go through a series of performance tests, including pressure test, sealing test, corrosion resistance test, etc., to ensure that it can work stably and reliably under various working conditions. Only products that pass these strict tests can be recognised as qualified sanitary tank bottom diaphragm valves, and ultimately be used in food, pharmaceutical and other industries that require very high sanitary conditions.
