Alfa Laval Tank Accessories
Enhance hygienic processing with reliable and effective tank accessories
Boost process performance with Alfa Laval tank accessories. These enhance process control, safeguard equipment and uptime, and improve process efficiency and product quality.
Key Benefits of Alfa Laval Tank Accessories

- Safeguard processes by controlling or limiting tank pressure with a relief valve
How Do Tank Accessories Work?
Each one of the Alfa Laval tank accessories enhances the hygienic processes in your tank. This includes enabling visual inspection without opening the tank, stabilizing tank contents with adjustable legs and base plate, or maintaining design pressure in pressurized tanks by relieving pressure, when required.
Alfa Laval Relief Valve
Protect tanks and processes with hygienic overpressure relief
Alfa Laval relief valves prevent vacuum or pressure build-up inside tanks or vessels used in the brewery, food and beverage, personal care and biopharm industries.
To protect against overpressure and vacuum conditions while filling or emptying the tank of liquid, Alfa Laval two-way relief valves are mounted on top of an atmospheric tank in hygienic process lines.
Key Benefits
- Overpressure and vacuum protection for hygienic process lines
- Designed for product flows up to 1000 hl/h
- Available in polyethylene or stainless steel variants
How It Works
Operating principle:
- Air flows out to avoid overpressure during filling
- Air flows in to prevent vacuum during emptying
Polyethylene relief valves: Contain two chambers with balls that rise to let air in or out.
Stainless steel relief valves: Use an oil bath to filter incoming air and protect hygiene.
Product Range
The Alfa Laval range of relief valves (RV) includes:
- Polyethylene models: RV130, RV400, RV400A, RV800 (up to 800 hl/h)
- Stainless steel models: RV600, RV1000 (up to 1000 hl/h)
Sight Glasses and Light Fitting
Reliably clear viewing quality for hygienic tank operations
Alfa Laval sight glasses are accurate gage glasses that permit direct distortion-free visual inspection of process conditions, products, liquid levels and cleaning inside vessels used in the dairy, food and beverage, personal care and biopharm industries.
Alfa Laval sight glasses provide clear, continuous and unobstructed visibility of processes or products in tanks or vessels. Quick and easy to install, Alfa Laval sight glasses provide reliable operation, low maintenance requirements and the means for early detection and response that can help prevent costly downtime.
The Alfa Laval sight glass range consists of seven different models that are mounted or welded onto or into pressurized, non-pressurized and high-temperature tanks or vessels, or pipe systems.
Made with borosilicate glass according to DIN 7080 and long-lasting, specially formulated gaskets, these sight glasses are resistant to different pressures, temperatures and can be used in various applications.
For more information on the different types of sight glasses, please refer to How it works and Documentation.

How it works
Construction:
The construction of the Alfa Laval range of sight glasses varies, depending on the type of sight glass. For more information, please refer to the specific type below.
Sight glass DIN 11851: Typically used in tanks with high pressures and temperatures, this bolted sight glass consists of a base flange, which is welded onto or into the tank wall, a cover flange, gaskets, a glass disc, nuts and studs. Provided that the flange is welded correctly onto/into the tank, the flange thickness guarantees a distortion-free location for the glass disc. The sight glass can be fitted with an optional miniVision light fitting.
Sight glass DIN 28120: The sight glass is engineered with a welding nozzle that is welded onto the tank wall, a grooved collar nut, a glass disc and two gaskets. The sight glass comes in sizes from DN50 (with a free view of 50 mm) to DN150 (with a free view of 150 mm). The sight glass can be fitted with an optional miniVision light fitting.
Sight glass types LKS 78, 105 and 120: Sight glass type LKS is available in three types. Sight glass type LKS 105 (free view: 105 mm) is designed for installation above the liquid level in pressure-less storage tanks. Sight glass types LKS 78 (free view: 78 mm) and LKS 120 (free view: 120 mm) are designed for pressure tanks. All LKS sight glasses consist of a threaded flange, which is welded onto the tank, gaskets, a glass disc and a retaining ring.
Sight glass Elongated: The elongated sight glass is used for the observation of the liquid level or reaction within the tank or vessel. It consists of a base flange that is welded into or onto the tank wall, a cover flange, a glass disc and gaskets. Two versions of the Alfa Laval elongated sight glass are available:
- DB version has a base flange with bolt tappings drilled through
- SL version has a base flange with blind tappings
Sight glass Metal-fused: Suitable for food processing and sterile applications, the Alfa Laval metal-fused sight glass is mounted on clamp fittings in accordance with DIN 32676.
Sight glass LKFL in-line: The LKFL in-line sight glass is used in processes that require observation of a product in a pipeline. It consists of a tube with two screw connections for the glass. The connections are placed opposite each other to enable positioning of the glass very close to the internal wall of the tube. An optional halogen light source, which is fitted onto one of the sockets, is available. The halogen light source consists of two stainless steel tubes assembled with a clamp. The standard LKFL connections are welding ends. Upon request, the LKFL is also available with male part connections.
Sight glass LKG in-line: The Alfa Laval LKG in-line sight glass is used in pipe systems where a visual observation of the product flow is necessary. Two types are available: the LKGG-1 and the LKGL-1.
The LKGG-1 consists of a perforated stainless steel shield tube fitted with a welding union at each end. A special glass tube is fixed in the shield tube so that it is unaffected by potential stresses in the pipelines.
The LKGL-1 is similar to LKGG-1, but has a stainless steel light fitting welded onto the shield tube so that the product can be illuminated.
Alfa Laval LKTC Tank Leg and Base Plate
Fully adjustable stainless steel support for freestanding tanks or vessels
The Alfa Laval LKTC Tank Leg is a fully adjustable stainless steel support for freestanding tanks or vessels. Sturdy and compact, it can stand either directly on the floor or, to ensure stability on uneven floor surfaces, on an optional steel base plate. The LKTC Tank Leg is capable of supporting maximum static loads of up to 160,000 N within an area of 7,800 mm2. Designed to stand on a base plate, the sphere-shaped tank feet are capable of supporting a maximum load of up to 19 tons.

Adjustable Support
Made of durable AISI 304 stainless steel, the Alfa Laval range of tank feet provides adjustable support for tanks or vessels. The LKTC tank feet can stand either directly on the floor or, to ensure stability on uneven floor surfaces, on an optional stainless steel base plate. The Sphere Shaped tank feet are designed to stand on a base plate.
Sturdy, Compact Design
LKTC tank feet are available in three sizes (3/4”, 1” and 1-1/2”), and are capable of supporting maximum static loads of up to 160,000 N within an area of 7,800 mm2. The Sphere Shaped tank feet are available in five sizes (½”, ¾”, 1”, 1-1/4” and 1-1/2”) and are capable of supporting a maximum load of up to 19 tons.
How It Works
Construction
The LKTC tank feet and Sphere Shaped tank feet consist of a cylindrical stainless steel piece that is welded onto the tank. The cylindrical piece houses an internal thread that fits onto and engages an adjustable cylinder-shaped spindle.
To adjust the tank feet to the optimal height, simply shorten or lengthen the spindle.
LKTC tank feet are designed to stand either directly on an even floor or on a stainless steel base plate where floor surfaces are uneven.
Sphere shaped tank feet can only stand on a steel base plate.
