Alfa Laval Single Seat Valves (SSVs)
Alfa Laval single seat valves (SSVs) are robust and reliable manual and pneumatic valves with a single plug design. Versatile and purpose-built, whether used for shutoff or changeover, these compact, modular valves are ideal for use wherever high standards of hygiene are required across the dairy, food, beverage, brewery, home-personal care and many other industries.
Key benefits of Alfa Laval SSVs
- Exceptional valve hygiene and durability
- Superior cleanability with smooth, no-crevice inner valve body
- Extended seal life due to defined seal compression
- Static seal leak detection for enhanced product safety
- Double lip seal protection against microbial contamination
- Full vacuum capability to ensure process integrity
- Wide range of flow rates and customizable options
- High reliability, low total cost of ownership, and easy maintenance
How does a single seat valve work?
Standard Alfa Laval single seat valves are operated by means of compressed air from a remote location. The actuator smooths operation and protects process lines, while directing or diverting fluids. The valve can be controlled using an Alfa Laval ThinkTop®.
Alfa Laval LKAP
The Alfa Laval LKAP is a pneumatic single seat valve with a single contact surface between the plug and the seat to minimize the risk of contamination. Compact and straightforward, it is designed for use as a remote-controlled shut-off valve for small flows and for dosing applications.
Key benefits of the LKAP valve
- Handles small product flows and dosing
- Straightforward, compact design
- Easy to maintain due to few moving parts
- Easy to clean with hygienic surface finish
Proven shut-off valve
The Alfa Laval LKAP seat valve is a quality pneumatic shut-off valve that is based on reliable, proven technology. It is ideal to handle small flow rates of up to 9 m³/h and purpose-built for specialty applications, such as a CIP supply valve to Unique mixproof valves or dosing valves in mixing applications.
Clean simplicity
Like all other hygienic Alfa Laval valves, the LKAP features a simple, straightforward design with the fewest possible components and minimal moving parts. Smooth surfaces and sanitary finishes contribute to good hygiene and cleanability.
Shut-off valve range
The standard Alfa Laval LKAP valve is a normally closed (NC) valve with a two- or three-port valve body (LKAP-V and LKAP-T, respectively). Upon request, the LKAP valve is also available as a normally open (NO) valve.
For more information, please refer to Documentation.
Compliance with most hygienic standards
Alfa Laval LKAP valves meet most standards requested in the dairy, food and beverage, and personal care industries. Please refer to Documentation for more information.
How does the LKAP work?
Construction
The LKAP valve consists of an actuator, double lip seal for stem, stem, EPDM sealing and valve body with welding connections. Visual indication of the valve position is provided.
For remote indication of the valve position, an optional reed switch position transmitter is available.
Operating principle
The Alfa Laval LKAP seat valve is a normally closed (NC) valve with a spring return that is controlled from a remote location by means of compressed air.
Options
- Fittings according to required standards
- Bracket with standard M12 sensors for indication of open and closed positions
- Product wetted seals of FPM or NBR
Alfa Laval SB Mini Flow Valve
The Alfa Laval SB Mini Flow Valve is a reliable single seat valve with a single contact surface between the plug and the seat to minimize the risk of contamination. Designed for working in a gas or liquid environment, it is used to close or divert small product flows when hygienic shut off and changeover are required.
Versatile shut-off or changeover valve
With its cost-effective modular design, the multi-application valve can easily be configured either as shut-off valves or change-over valves to meet virtually any requirement. Choose from a pneumatic angle valve, pneumatic two-way valve, drain valve with fittings or drain valve with fittings and clip-on.
Hygienic design
Made of 316L product wetted steel parts, the Alfa Laval SB Mini Flow Valve is designed for fast, easy cleaning, thereby minimizing the risk of contamination. The valves are supplied with threaded pipe couplings for 6/8-mm pipe.
Key benefits
- Versatile shut-off or changeover valve
- Handles small flows of liquid or gas with ease
- Compact and hygienic design
- Low maintenance
- Fast-acting
How it works
Construction
The valve comprises valve body, inlet and outlet. It can be used as an integral part of a SCANDI BREW® tank top system.
Operating principle
The valves are in pneumatic or manual execution.
