Geared motors power rotary valves

UK rotary valve manufacturer, Rotolok, has selected Flender Motox geared motors from Siemens Automation and Drives, for their strength and reliability.

Dan McCauley, Rotolok's founder and managing director, said: 'Our valves are widely used in processing industries like sugar, cement, polymers and pharmaceuticals, and we needed strong and reliable geared motors to complement them.

'The Flender Motox series has everything we need.' Rotolok specifies smaller Motox geared motors (size Z38 and Z48) - in Imperial sizes for its US customers - in its ranges of rotary valves.

The Rotolok valves come in sizes from 915mm upwards, rated at up to 3hp.

Standard valves have pressure differentials to 20psi and temperatures to 400C, although the company makes specials to handle temperatures up to 1,200C and pressures up to 350psi.

McCauley also praised efficient deliveries to Rotolok's base in Tiverton, Devon, as Rotolok buys a significant number of geared motors every year.
