Alfa Laval Unique Tank Outlet Mixproof Valve

The Unique tank outlet mixproof valve features the same advantages as the Unique mixproof valve, but is specially designed for mounting directly on the tank wall at tank inlets and outlets. For tank inlet and outlet applications, the Unique tank outlet (TO) mixproof valve offers full drainability and provides cleanability all the way up to the tank without any risk of cross-contamination.

Concept

Unmatched flexibility is the concept of this simple mixproof valve. Its modular design provides the perfect solution for all mixproof tank outlet applications involving non-compatible fluids within the pipeline and tank. The body and outlet can be easily positioned by the loosening of a single clamp. The body is connected to a flange that is welded directly to the tank.

The tank flange maintains TÜV approval AD 2000 and comes with an EN10204 (3.1) inspection certificate 3.1. The Unique TO is available in two inch to four inch outlet (ISO tube) sizes. The design of the valve allows it to be installed in a horizontal configuration.

Working Principle

The Unique TO is remotely controlled by means of compressed air. The valve is supplied in a normally-closed (NC) configuration. The valve maintains two independent plug seals, forming a leakage chamber which is open to the atmosphere at all times. In the unlikely event of a leak, product will enter into the leakage chamber and be discharged through a leakage chamber outlet. As the valve opens, the leakage chamber closes allowing product to flow from the tank to the pipeline. The valve is protected from any pipeline water hammer thanks to a balanced plug design that limits the speed of the seating of valve plug when closing with the direction of the product flow. The valve has multiple cleaning options, configurable to the needs of the specific application. There is practically no spillage of product when operating the valve.

APPLICATION

Unique TO meets the typical demands of a process valve in the sanitary industry. It is also suitable for products with solids. Cleaning of the plugs and seats are performed by means of seat lift during normal cleaning procedure. This valve also includes a balanced plug in the pipeline that protect against pressure shock in the pipeline when closing in the direction of product flow. Features include an actuator with balanced seat lift integrated and standard balanced plug in pipeline. Unique TO is the choice for standard solutions.

  1. Unique TO
  2. Unique TO long stroke (size 2.5 inch to 3 inch ISO63.5-ISO76.1 and DN65-DN80)
  3. Unique TO with external cleaning

Unique TO with external cleaning meets the highest demands for hygienic processing. During the cleaning process, the plugs can be lifted independently to ensure cleaning of plugs and seats together with their corresponding pipe. At the same time or separately the leakage chamber and balanced plugs can be cleaned with our SpiralClean system. It has few product wetted seals and allows no product spillage during operation. This valve is the choice for solutions requiring the highest level of hygiene and is suitable for applications with sticky products, products with high content of solids or applications where "close to aseptic conditions" are wanted. Its features include an actuator with seat lift integrated and SpiralClean of leakage chamber and balanced plug. Unique TO with external cleaning is the choice for highest hygienic cleaning.

SpiralClean

The Unique TO offers the Alfa Laval SpiralClean system to clean the balanced plug and leakage chamber, helping to meet the high hygienic standards of the sanitary industry. All external clean-in-place (CIP) systems for Unique include the SpiralClean design as standard. Another benefit of the SpiralClean system is that it allows the Unique TO to operate under near-aseptic conditions by applying steam to the CIP pipes, thereby forming a steam barrier to the atmosphere.

Options

The Unique TO is designed with user flexibility in mind. The user can choose additional options as warranted by the application (i.e. stricter hygienic requirements, challenging downstream flow characteristics). The modular design of Unique TO uses common components from the Unique valve family, reducing the requirement for spare parts inventory while providing an extremely serviceable valve. The valve design consists of a single valve body, connected to either a tank flange or a stub flange via a clamp.

The drawings below give an overview of all options when choosing the valve to fit your process, thus demonstrating the actual flexibility of the Unique Mixproof tank outlet valve. The Unique TO concept offers balanced plug in pipe line, seat lift, CIP for the plugs and leakage chambers and any combination in between.
