The German LESER 4834 series safety valve is a high-performance safety valve designed specifically for hygiene industries such as food, beverage, pharmaceutical, and chemical. It hasThe structural design, strict material selection, and extensive certification support can meet the application scenarios of high cleanliness and high safety requirements.

1、 Product Features

1. Sanitary grade design：

• Using sterile flange or sleeve connections, as well as sterile threaded connections, to ensure the hygiene and safety of valves and piping systems.

• All elastic sealing components are exposed, easy to clean and disinfect, and prevent microbial growth.

• Springs have a very wide adjustment range to adapt to pressure requirements under different working conditions.

• Single stem, dual guide, center positioning ball design ensures excellent sealing and service life of the safety valve.

2. No dead zone design：

• The safety valve body adopts a dead zone free design, which avoids the possibility of residual medium during the discharge of the safety valve, thereby preventing the risk of cross contamination.

• Few components, strong interchangeability, compact exterior structure, simple and convenient disassembly and assembly, easy to clean and maintain. The set pressure of the safety valve after cleaning does not need to be recalibrated, saving time and cost.

3. high-performance materials：

• The valve body is made of 316 and 316L stainless steel, which has good corrosion resistance and high temperature resistance.

• The surface of the valve body and upper cover is subjected to electric polishing treatment, resulting in low surface roughness and difficulty in adhering to media, further improving hygiene performance.

• The nozzle and valve core are made of stainless steel materials such as 316 and 316L, and the sealing surface adopts non-metallic soft sealing to ensure reliable sealing performance.

4. safety protection：

• Adopting a closed valve cover design to prevent medium leakage and external pollution.

• The use of EPDM bellows for sealing the upper cover and valve stem improves the reliability and durability of the seal.
