Alfa Laval is introducing an aseptic double-seat valve, Alfa Laval Aseptic Mixproof Valve, for sterile process applications is based on the same modular architecture as the aseptic version of the company’s Unique Single Seat Valve, SSV.
The new valve reduces the total cost of ownership for dairy, food, beverage and other manufacturers by up to 45% compared to the leading aseptic double-seat mixproof valves.
Estimated savings are based on a comparison of capital expenses and maintenance costs of an aseptic 2.5″ valve over a five-year period if service is done onsite.
If maintenance is done offsite by a third-party provider, competing technologies become even more expensive.
“Steel bellows and seal replacements are the most expensive maintenance costs for leading brands,” says Anders Mose Lyhne, product portfolio manager, Valves and automation.
“Instead of steel bellows, the Alfa Laval Aseptic Mixproof Valve uses the same diaphragm with a PTFE face and reinforced EPDM backing which, over the past eight years, has been well-proven in our Alfa Laval Unique SSV Aseptic Valve.”
“This drastically reduces the total cost of ownership of our double-seat valve, yet still ensures the hermetic seal required for sterile processing.”
The cleaning and sterilization flow characteristics have been proven by CFD flow simulations.
The valve ensures product safety through full protection against the intrusion of harmful microorganisms, even during unwanted pressure spikes.
Built on the same Alfa Laval Unique SSV platform, this aseptic double seat valve is easy to mount either in a horizontal or vertical position.
There are three seat-lift versions, five steam valve types and a range of options for steam temperature monitoring.
Initially, the Alfa Laval Aseptic Mixproof Valve range will include these valve sizes, which meet most manufacturer requirements: ISO 51 mm (2”), 63.5 mm (2.5”) and 76.1 mm (3“).
