Sanitary check valve

The safe operation of every pipeline system in food and beverage production lines, pharmaceutical clean rooms, and cosmetics production lines is crucial to the quality of the final product. As the core device for ensuring one-way fluid flow, sanitary check valves are building a solid defense line for the entire production process with reliable performance.
The sanitary check valve produced by Zhejiang Santai Vacuum Valve Co., Ltd. strictly selects 304 and 316L stainless steel as the valve body material. This material is not only corrosion-resistant in complex acidic and alkaline environments, but also has a smooth and even inner wall after special polishing treatment, which can effectively prevent the growth of bacteria due to residual media and fully comply with strict hygiene certification standards such as GMP and FDA. For different working conditions, we offer two types of valve core structures: rotary opening and lifting. The rotary opening design allows the valve to have less pressure loss when transporting high flow media; The lifting valve core adopts a dual sealing structure to ensure that the medium will not flow back and leak during frequent opening and closing.
The working principle of valves originates from the clever application of fluid mechanics. When the medium flows in the specified direction, the fluid pressure will push the valve core to open smoothly, ensuring smooth transportation; Once a reverse flow trend occurs, the valve core will quickly and automatically close, nip the risk of reverse flow in the bud. This rapid response mechanism has helped cooperating dairy companies avoid raw material contamination accidents caused by pipeline reflux.
From fresh milk delivery pipelines in dairy companies, to sterile water circulation systems in pharmaceutical factories, and to raw material blending in cosmetics companies, Santai’s sanitary grade check valves have become a trusted choice for many leading companies in the industry. After adopting our lift check valve, a well-known pharmaceutical group effectively controlled cross contamination during drug production and significantly improved production stability.
Faced with increasingly strict hygiene requirements in the industry, Zhejiang Santai Vacuum Valve Co., Ltd. has always been at the forefront of technological innovation. We have established a comprehensive quality control system covering the entire process from raw material procurement to finished product testing. We have also collaborated with multiple research institutions to develop a new generation of sanitary grade check valves with self-cleaning capabilities. In the future, we will continue to deepen our expertise in the field of fluid control, providing higher quality products and services to continuously empower the safe operation of sanitary pipeline systems in various industries.
