Colin Kirkland shares best practice when installing CSA’s ATHENA direct acting float valve. Used in filling control applications, its unique ability to regulate without minimum operating pressure sets the valve apart.
The ATHENA valve is a direct acting, self-cleaning control valve designed to fill reservoirs, tanks and channel applications. The ATHENA’s flexible design allows it to be installed and adapted for a diverse range of fill controlling applications.
The valve is designed to modulate inlet flow, to maintain a constant water level in a tank or reservoir. One of the benefits of the ATHENA valve is its ability to regulate the inflow, regardless of inlet pressure. The direct acting float mechanism is internally balanced, and does not require a minimum operating pressure to open and regulate.
The ATHENA valve is available from 25 to 300 mm in size, in both threaded and flanged configurations.
When installing the ATHENA direct acting control valve, it’s important to isolate the product. This can be achieved using an inlet isolation valve or butterfly valve during maintenance and inspection. There are many factors that contribute to effective pipeline design, some of these include:
During the installation process, the ATHENA valve can be mounted directly inside a tank. Alternatively, the valve can be mounted outside the tank, with the arm entering the vessel. This is made possible due to the flexibility of the valve design – the inlet valve can be rotated in 45 degree increments to suit a variety of tank assemblies.
When the flow rate exceeds the value of a single ATHENA valve, there is no problem with mounting several units in a single tank installation to achieve a higher flow rate.
