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/UKCA Certified 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.
