        Air Locks

Rotary valves (Air locks) serve as crucial components in dry bulk handling systems, controlling material flow, maintaining system pressure, ensuring consistent feeding, and enables product metering.

AL/AXL

All-round rotary valve for metering and conveying powders and granules

The AL and AXL rotary valves, adept in metering and conveying powdersand granules, feature modular designs for various configurations. With its larger inlet, AXL excels in managing products with challenging

flow properties. These stainless-steel rotary valves are ideal for food and pharmaceutical

sectors, which meet USDA Dairy and EC1935/2004 standards, offering easy disassembly and high hygiene.

MZC models simplify rotor and end cover removal by adding rails, while the adaptable AML variant transitions between round and square interfaces, enhancing versatility in system design.

AML

All-round rotary valve with one round and one square flange

The AML rotary valves are suitable for many applications in the metering and pneumatic conveying of products in powder and granular form. These valves can also act as a transition piece from round to square and vice versa. The AML rotary valve range also includes USDA Dairy-accepted models and versions compliant with the EC1935/2004 directive for sanitary use in the food and pharmaceutical industry. These stainless-steel rotary valves are easily detachable and meet the highest hygienic standard

USAL

All-round rotary valve with two square flanges

The USAL rotary valves have been designed for many applications in the metering and pneumatic conveying of products in powder and granular form. The USAL has square inlet/outlet flanges. It has an enlarged inlet, Designed for applications where inlet size is more important than capacity, or for handling products that flow poorly.

SAL

Heavy-duty sanitary rotary valve

The SAL rotary valve is a low-capacity rotary valve with a highly polished surface inside and outside. The SAL is suitable for metering applications where very high hygienic standards, and ease of operation and cleaning are required. The complete rotary valve can be dismantled for inspection and cleaned in minutes, thus reducing eventual downtime and production loss.

GL

Granular rotary valve for gravity feed or pneumatic conveying

The GL rotary valves are specially designed for gravity feeding and pneumatically conveying granular products. The configuration of the body and rotor have been developed specifically to minimize product degradation while retaining the best possible pocket-filling efficiency.

NR347

Exact fit for replacing your Niro rotary valve

Thinking of replacing your existing Niro rotary valves? Our NR (Niro Replacement) rotary valve matches the outer dimensions of the existing Niro rotary valve in your system, Meaning they are exactly fit for most of the time. 

Our replacement rotary valves are based on the AL250 model, and made of stainless steel. 

They meet all hygiene and safety standards, ensuring their future-proof value.

BL/BXL/BXXL

Precision metering and pneumatically conveying with a modular design

Engineered for precision in metering and pneumatic conveying, Our BL, BXL, and BXXL rotary valves easily handle powder and granular products. Their modular design allows for diverse configurations. The BXL rotary valve, with its enlarged inlet, excels in applications demanding larger inlets or processing products that do not flow smoothly, With the BXXL offering an even greater inlet size. Crafted from cast iron, Stainless steel, or aluminum, these rotary valves are quickly detachable, maintaining the highest hygienic standards. The BL, BXL and BXXL models also come in MZC versions, featuring supportive rails for effortless end cover and rotor removal without damaging the housing.

MALD/MLD

Ideal for vacuum conveying, bulk bag unloading, cyclone applications, and general-purpose use

The MALD and MLD medium-duty rotary valves offer exceptional value and versatility for various applications.

Ideal for vacuum conveying, big bag unloading,

Cyclone applications, and general purposes, Both rotary valves are distinguished by their simple construction

and direct drive. Using the AL rotary valve body with two round flanges, The MALD rotary valve is optimal for powder handling. In contrast, The MLD rotary valve features an ML rotary valve body with larger round and square flanges, enhancing its efficiency with free-flowing products and facilitating transitions between different connections.

DL

Dust lock rotary valve designed for filter applications

The DL dust lock is a rotary valve with a dedicated design for filter applications. It can be used with dust filters, cyclones,

product separators, and dosing systems.

The universal flanges on both sides of the rotary valve are used for round or square connections. This application is much more sensitive to dust explosions; therefore, we have ATEX-certified this valve for equipment or protective systems (explosion barriers).
