Nu-Con Release Next Generation Rotary Valves
Nu-Con has now officially released the next generation of the Rotor Detection System (RDS2) for Rotary Valves. Nu-Con’s ‘Rotor Detection System’ is already extensively used by both food and infant formula manufactures when rotor scrapping must be immediately detected to prevent the contamination and downgrading of the product.
A rotor may come in contact with a valve housing, if a valve is incorrectly assembled, or if process conditions change and product temperature increase substantially causing expansion within the Valve. When fitted with Nu-Con RDS, a warning signal is sent to the operators via the plant SCADA System, allowing the valve to be automatically shut down, or even prevented from starting up, if a faulty condition exists after reassembly.
The ‘Rotor Detection System’ uses a modified valve design, in which the rotor is electrically isolated from the housing. The next generation RDS2 has incorporated improvements in performance, construction and durability. The design changes have been made to allow more flexibility in the operation of the RDS, reduce servicing, provide a simpler rotor design and a more robust probe arrangement.
All the new design components have be thoroughly tested during the past year.
The new electronics package is a much more powerful and versatile arrangement. Specifically it is designed to have adjustable sensitivity depending on process and products. Primarily this has been intended for in-line CIP applications with conductive CIP solution now able to be run though the Valve, however it has also been found to give improved performance for standard applications with various products.
The setpoint and diagnostic functions incorporated into the new electronics package can be easily linked into the plant SCADA system. ATEX versions of this RDS system are also available.
This new design will now become the standard for any RDS equipped valve in the future.
