The German LESER 4884 series safety valve is a high-performance safety valve designed specifically for hygiene industries such as food, beverage, medicine, and chemical. With its structural design, strict material selection, and extensive certification support, it can meet the application scenarios of high cleanliness and high safety requirements. The characteristics of this series of products are as follows:

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.

2. CleanService

-Adopting a low dead space and seamless structure, the internal surface smoothness meets DIN 11866/ASME BPE standardsStandard, convenient for CIP (cleaning in place) andSIP (disinfection in place)Industries that meet hygiene requirements such as food, beverages, and pharmaceuticals.

3. Materials and Sealing

-The valve body is commonly made of 316L stainless steel (1.4404, 1.4435), with optional PTFE full lining or soft seal (FDA flexible elastomer), suitable for corrosive or high-temperature mediaMaintain excellent sealing performance in a high-quality environment.

4. Multiple connection methods

-ProvideFlanges (DIN EN, ASME), threads Multiple sterile connections such as clamps, compatible A piping system within the range of DN 15 to DN 100 (1 to 4 inches).

5. Low dead zone ratio &High surface quality

-Design to minimize dead space inside the valve, ensuring minimal loss of medium during pressure relief, and installing the valve cover flush with the valve body for easy on-site cleaning and maintenance.

6. Compliant with international certification

-Already approved by T Ü V，CE (PED Class IV), ASME Section VIII Div 1 and other certifications, meet the EU Pressure Equipment Directive (DGR 2014/68/EU) and US API 520 standards.

7. Widely applicable in various industries

-Mainly used in chemical, oil/gas, energy, pharmaceutical, food/beverage, brewing, dairy products, beverage canning, storage tanks, steam boilers, automated production lines and other process systems that require high flow and clean protection.

8. Optional attachments

-It can be equipped with bellows protection valve cover, soft sealing gasket, gas sealing gasket, manual/pneumatic opening device, etc., to meet the special needs of different working conditions.

Summary：The Leser 488 series is a full lift safety valve designed specifically for "large capacity, clean services". It combines high reliability, excellent hygiene performance, and diverse connection and material options, and is widely used in industrial fields that require safety and hygiene.
