Nguyên lý làm việc của van single seat SRC và SSV của Alfalaval
Actuators
- Stainless steel actuators with caged spring
- 3 diameter sizes : 89 mm, 133 mm, 199 mm
- Field reversible with no additional parts (NC - NO)
SRC - Single Seat Valve Features and Benefits
- Few moving parts ensures high reliability
- Double rubber lip seal wipes the stem clean during both upward and downward travel No O-rings
- Flat seat design for longer seat life
- High safety because of "caged" spring
- Field reversible actuator (NO - NC)
- Field rebuild from manual to remote
- Field rebuild from sanitary to aseptic
- Easy to service
New Unique SSV will replace present SRC valve

Unique SSV Features
Process safety with peace of mind:
- Built on a well-proven platform from an installed base of more than one million Valves.
- The one piece body means strength, ensuring reliable safe production
- Traceability in compliance with the EU Food Regulation 1935/2004.
- The upgraded sealing concept, with defined compression of sealing with metal-to-metal contact, ensures safe production.
- Actuator gives higher performance, ensuring reliable safe production.
Unique SSV Features
Optimum hygiene:
- The body of the Unique SSV has no welds
- Surface finish, Ra ≤ 0,8μm, meeting the highest standards of hygiene
- Superior cleanability by the ball-shaped body with no dead zones
- Valve plug with enhanced cleaning-in-place capabilities
- A double working lip seal minimizes risk of contamination
- The valve meets all hygenic design standards and is EHEDG certified.
- Authorized to carry the 3A symbol
Great Saving of ownership:
- Traceability (EU Food Regulation 1935/2004) is simple as one piece of steel generates one piece of documentation.
- Superior cleanability saves time and cuts cleaning fluid costs
- Actuator gives higher performance
- Upgraded sealing concept ensures longer seal life.
- Aseptic one piece design - Less spare parts and less stock costs
