CIP/SIP-Capable Valve for Hygienic Overpressure Protection in High-Purity Steam, Gas, and Liquid Applications

Aseptic Safety Relief Valve(model HSS) feature an angle-type connection design, specifically engineered for use with clean steam, air, water, and other gases or liquids compatible with high-purity construction materials. These valves provide critical overpressure protection for steam equipment, pressure vessels, and pipelines, making them an ideal solution for the food, beverage, and pharmaceutical industries.

New Product

Application of Aseptic Safety Relief Valve

• Overpressure protection for clean steam equipment, pressure vessels, and pipelines.
• Ideal for high-purity systems in the Food, Beverage, and Pharmaceutical industries.
• Suitable for handling clean steam, air, water, and other compatible gases and liquids.
• Designed for hygienic environments requiring self-draining and isolated product chambers.

Key Features and Benefits of Aseptic Safety Relief Valve

• Entirely machined from solid bar stock material (AISI 316L / 1.4404), providing superior structural integrity and a high-purity surface finish compared to cast components to minimize bacterial growth.
• Equipped with elastomer bellows that completely isolate the product chamber from the spring housing, ensuring the process media remains uncontaminated and protected from the internal spring mechanism.
• Features a specialized self-draining angle-type design that prevents fluid entrapment and "dead legs," making it ideal for systems requiring high-level cleanliness and frequent sterilization.
• Internal wetted parts are finished to ≤ 0.51 micron Ra (SF1) and undergo ultrasonic cleaning to meet stringent pharmaceutical and food industry standards for effective Clean-in-Place (CIP) and Steam-in-Place (SIP) processes.
• Offers an optional pneumatic lifting device for automated operation, allowing the valve to be forced open during CIP/SIP cycles to ensure thorough cleaning of the valve seat without manual intervention.
• Designed in full compliance with DIN EN ISO 4126-1 and the Pressure Equipment Directive (PED), ensuring certified overpressure protection for clean steam, gas, and liquid applications

Frequently Asked Questions(FAQ) about Aseptic Safety Relief Valve

Q1: Why is a self-draining design critical for sanitary safety valves?

It prevents bacterial growth by eliminating fluid entrapment and "dead legs". The HSS’s solid bar stock construction and self-draining body ensure maximum hygiene in pharmaceutical and clean steam applications

Q2: How does the pneumatic lifting device improve CIP/SIP efficiency?

It enables automated valve opening during cleaning cycles via a Ø6 air connection. This ensures thorough sterilization of the valve seat without manual intervention or disassembly, significantly reducing maintenance downtime.
