How to ensure production safety with sanitary pressure reducing valve

In industries with high hygiene standards such as food and pharmaceuticals, the use of sanitary pressure reducing valves to accurately control pipeline pressure, achieve rapid cleaning and sterilization, and provide intelligent monitoring and early warning can effectively prevent equipment overload, pollution, and safety accidents. With its all-stainless steel, no-dead-angle design, ±1% voltage stabilization accuracy, and Internet of Things functions, this equipment has become the core solution for enterprises to build a solid production safety line of defense.

Industry pain points force technology upgrades

Sanitary pressure reducing valves are widely used in liquid food, vaccine production, bioreactors and other scenarios. The global market size is expected to reach US$1.2 billion in 2025, with a compound annual growth rate of 8.7%. As a major producer, China's relevant national standards (GB/T 21384-2023) have strengthened the testing requirements for valve hygiene performance this year.

In industries with strict hygiene requirements such as food, beverages, pharmaceuticals, and cosmetics, sanitary pressure reducing valves ensure production safety through the following key mechanisms:

1. Accurate pressure control

Through the spring and diaphragm linkage, the pressure changes are sensed in real time, and the valve core opening is automatically adjusted to control the downstream pressure within ±5% (some precision types can reach ±2%), so that the outlet pressure is automatically kept stable.

2. Prevent overpressure

If the pressure exceeds the set value, the valve opens, allowing the fluid to enter the processing equipment and reduce the pressure.

3. Prevent vacuum

If the pressure is lower than the set value, the valve closes to prevent further vacuum and potential damage.

4. Safe operation

By maintaining a consistent pressure of 0.2-1.0Mpa and reducing the water hammer effect, the valve ensures safe and reliable operation of the processing equipment, preventing equipment damage and product loss.

5. Materials and sanitary design

The use of 316L stainless steel meets FDA/EHEDG standards, high-grade materials, smooth surface, structure without dead angle design, internal polishing Ra≤0.8um, etc. to avoid residue accumulation, prevent pollution, minimize dead angles and gaps, and reduce the risk of bacterial growth and contamination, which is crucial for food, beverage and pharmaceutical processing.

6. Sealing protection

The use of food-grade seals such as EPDM/FKM that meet FDA standards achieves zero leakage (leakage <0.01%) and prevents external contaminants from infiltrating.

7. Support online CIP and SIP

The pressure reducing valve supports online CIP cleaning and SIP sterilization to ensure that no microorganisms are generated inside the valve body and prevent product contamination.

8. Installation and maintenance

No professional tools are required. DONJOY sanitary preddure reducing valve body can be quickly disassembled and assembled through the clamp and the internal sealing ring can be checked for leakage to ensure safe operation of the product.

Safety in production is no small matter, and equipment selection must come first. "With stricter industry supervision and technological iteration, sanitary pressure reducing valves have evolved from "optional accessories" to "safety rigid needs". Enterprises need to combine their own processes to choose compliant and intelligent pressure reducing solutions to build the last line of defense for production safety.
