Sanitary Safety Relief Valves

Our sanitary pressure safety relief valves protect pressure vessels and process equipment by automatically opening at a preset pressure. This prevents overpressure conditions that could compromise system integrity. These hygienic pressure relief valves are widely used in industries such as food and beverage, pharmaceutical, cosmetics, and personal care.

Why Choose Steriflow’s Sanitary Safety Relief Valves?

A key advantage of our sanitary safety relief valves is their reusability. Unlike rupture discs that require replacement after activation, these valves automatically reset after relieving excess pressure, ensuring long-term cost efficiency. Manufactured in the USA, they meet ASME Section VIII and CE/PED certification standards for reliable performance and compliance.

Our sanitary safety valves meet strict sanitary standards, featuring:

• High cleanability (L/D < 1.5) for superior hygiene
• Smooth, electropolished surfaces (20 Ra µin / 0.5 Ra µm)
• FDA & USP Class VI wetted parts for compliance with pharmaceutical and food safety regulations
• Manual or pneumatic lift options for Clean-in-Place (CIP) compatibility
• Bellows-sealed models to isolate the process medium from valve internals

Designed for Hygienic & Aseptic Applications

Our sanitary pressure relief valves are ideal for:

• Bioreactors & fermenters
• Pharmaceutical formulation vessels
• Clean air & gas distribution systems
• Clean steam systems
• WFI (Water for Injection) & USP Purified Water (PW) vessels
• Any aseptic or hygienic process requiring overpressure protection

We offer a range of sanitary safety relief valves, including:

• SSRV-81 Series – Relief pressures from 232 psi to 500 psi
• SSRV-81V Series – Relief pressures from 13 psi to 232 psi
• SSRV-83X Series – Relief pressures from 12 psi to 232 psi

Note: Valves with set points below 15 psi do not require an ASME UV stamp.
