RotaSafe Detection System

Instant contact detection to protect your process

The rotor protection system RotaSafe is designed to instantly detect any contact between the rotor and valve housing while at the same time sending a signal to the panel to isolate power to the drive motor. It will primarily be of interest to customers where product contamination due to metal to metal contact is a significant issue.

RotaVal RotaSafe

RotaSafe – Rotation contact monitor

RotaSafe has been designed to protect your process and your products from contamination. As with any rotating parts, such contamination can occur for a number of reasons:

Ingress of ‘tramp’ material in the working clearances
Excessive load on the Rotor causing deflection
Product build-up (glazing) causing rotor shift
Bearing failure
Excessive temperature
Incorrect assembly / maintenance
Lack of maintenance

Your advantages with RotaSafe

Prevents valve material shedding into and therefore contaminating the product being handled
Protects valve components from serious damage
Prevents valve start-up if assembled incorrectly
Prevents damage to ATEX Autonomous Protection System Valves which can lead to invalidation of ATEX certification
Validated as ‘Simple Apparatus’ by our notified body (Baseefa) by complying with clause 5.7 of EN60079-11.2012
The control panel is programmed to eliminate ‘nuisance tripping’
Control Module is available for panel mounting or in stand-alone panels for one or multiple valve installations
Signals indicate: Contact Detection – Power On/Off – Detection Circuit Failure
Can be retrofitted to existing rotary valves
