Sanitary Safety Relief Valves
ASME Section VIII compliant, Created and Designed in US
The SSRV Sanitary Safety Relief Valve is designed to relieve over-pressure upset in hygienic and aseptic process and clean utility systems. The SSRV is designed to be manually set to open at a predetermined pressure to protect pressure vessels and other equipment from being subjected to pressures that exceed their design limits.
Applications:
- Bioreactor - Fermenter vessel and vessel jackets
- Formulation and other Pharma process vessels
- Clean Air I Gas distribution systems for point of use distribution
- Clean steam systems
- WFI and USP PW vessels
- Any hygienic or aseptic process vessel or system
- National Board certified to ASME VIII
- High cleanability: L/D < 1.5
- Standard surface finish ASME BPE SF1, 20 Ra μin (0,5 Ra μm) is standard. ASME BPE SF5 and SF4 15 Ra μin (0,4 Ra μm) optional. Electropolished optional
- FDA and USP Class VI seats, o-rings and bellows seal
- Bellows seal isolates process from valve internals when valve is open or closed on 83 and 83X Series
- ASME BPE Tri-Clamp and Tube weld end connections are standard. NPT connections available on SSRV-81 Series
- ASME SA479 316L, AL6XN, Hastelloy C-276 are standard
- Steriflow Premium Cleaning Available – consult factory for details
