Dubbing it a subterranean solution, Sipos has introduced variable speed actuators for valve control. According to Sipos, the new design uses concrete rings as an alternative to shafts and tunnels.

Sipos points out that built-in shafts and tunnels, traditionally below ground systems are costly to construct, and extending the network or providing ongoing maintenance is expensive and preventing ingress of water, soil and other particulates is challenging. Sipos says that the ‘concrete ring’ solution has, therefore, been introduced, making it ideally suited for the application.

The manufacturer lists the following product features and advantages:

The actuators can be mounted on a below-ground valve, with the electronics unit installed in a separate, readily accessible, above ground cabinet.

An integrated frequency converter protects motor controls, making the product a ‘fit-and-forget’ solution, ideally suited for below-earth application.

The underground application comes with an eight-year servicing cycle and IP68 protection class, which confirms the product’s high corrosion resistance.
