A Rota Val product story
Edited by the Engineeringtalk editorial team Mar 6, 2006

Diverter valves used by food manufacturer in Brazil to handle various products including MSK, maltodextrin, starch, lactose and sucrose.

Rota Val has won an order for seven PS Diverter Valves from a international food manufacturer to be installed in a production plant in Brazil.

Consisting of five PS90 and one each PS65 and PS100, the valves will be handling various food products including MSK, maltodextrin, starch, lactose and sucrose.

The valves are made in 316 stainless steel and include FDA-approved seals, double-acting pneumatic torque actuators, solenoid valves, position switches, pressure gauges and pressure switches to warn of inflatable seal failure.

All valves and associated ancillaries are constructed to comply with the Atex Zone 22 dust explosion prevention regulations, and have a bead blast finish and smooth contact surfaces to reduce product flow disturbance.

Designed to operate within a lean phase conveying system working at 0.8barg, the valves are used in diverging mode to manage the flow of powders from storage to process plant under PLC control.

Solenoid valves, pressure gauges, connections and related fittings are installed and prewired on the PS valve housings by Rota Val to provide fast, simple installation and commissioning.

The valves were designed to be easily stripped down and cleaned in place with little downtime and operator effort.

Suitable for vacuum, lean and dense phase conveying, versions are available in a choice of surface finishes.

Couplings may be pipe, flanged, plain pipe or quick-clamp FDA-approved.

Versions can be supplied for inert or reactive gas conveying applications where the outer casing may be sealed and pressurised to eliminate any possibility of gas or dust emissions.

Standard PS valves with internal pipe diameters from 20 to 200mm are available, but custom versions can also be made.
