Unique SSV Aseptic

Concept

The Unique Single Seat Aseptic Manual Valve meets the highest demands of your process in terms of hygiene and safety. Built on the well-proven Unique SSV platform it features a one-piece diaphragm to ensure hermetic sealing towards the atmosphere. The valve is designed for aseptic processing and it is available in a one or two body configuration as well as an tank outlet valve configuration.

Working principle

The valve is a manual operated seat valve in an aseptic and modular design for a wide field of duties, e.q. as a shut-off valve, as a change–over valve, as a tank outlet valve or as regulating valve. The Regulating Valve is used for control of pressure and flow and the plug can be fixed in the adjusted position with a lock screw.

Standard Design

The Unique SSV Aseptic Manual Valve comes in a one or two body configuration. With its module built structure it is designed for flexibility and easy customization through the electronic configurator (CAS). The Unique SSV Aseptic Manual Tank Outlet Valve comes in a one body configuration, which can be delivered with or without a tank flange. The valve body is clamped to the tank flange and can be turned in any position if the clamps are slightly loosened. The tank flange is welded directly into the tank.

How it works

Operating principle

The Alfa Laval Unique SSV is an air-operated seat valve that is remotely operated by means of compressed air. The valve generally has two working ports for air supply in and for process air supply; for changeover valves, a third port is required.

Unique SSV Aseptic

Fully modular with the proven design of the Unique SSV the aseptic single seat valve is equipped with a hermetic sealing diaphragm that ensures true aseptic conditions during operation. It hermetically seals against intrusion from the atmosphere and ensures full protection against the effects of microorganisms.

With a “sandwich construction” of PTFE on the product side, EPDM and an enforcing mesh, the aseptic diaphragm is optimized to guarantee reliable performance and long lifetime. In open position the one-piece diaphragm is mechanically supported by the valve to reduce wear and increase endurance.

The Unique SSV Aseptic valve is available in both pneumatic and manual configurations.
