Founded by Dan McCauley in the United Kingdom 1973, Rotolok designed and subcontracted work from an office facility in South East England. The company quickly expanded and relocated to Devon in the South West building their own factory giving the ability to manufacture all key equipment.

With continued growth the millennium year saw Rotolok commence their move to new headquarters. The newly constructed premises, of 50,000 sq. ft., initially contained the group sales and administration departments, while also providing additional and much needed new factory production space.

Our Vision and Values

Rotolok Founder Dan McCauley

In 2007 the move was complete. The modern site allowed Rotolok to centralise its fabrication workshops along with the sales and administration departments for the entire Rotolok Holdings Group. To meet ever increasing market demand, Rotolok re-equipped its Machining and Fabrication facility with the addition of high technology horizontal CNC machining centres with both six and twelve pallet pre-loading stations. The latter having replaced 3 CNC dual pallet machines

This £2 million upgrade enabled production to substantially increase, without any impairment to quality as well as giving the company greater flexibility as the machines can be programmed to work several hours unmanned, keeping their production up and the costs down.

A further benefit comes with the machining and drilling of large end covers, taper bore valves and large valve bodies. The company now has the facility of covering the entire range of products in house, from Rotary Valves through to Conveying Diverters and Slide Valves.

This upgrade ensures accuracy, interchangeability and cost control giving our customers a high precision valve at a competitive price.

Rotolok opened its North American facility in 1982, and moved into its current 12,000 square foot facility in Monroe, NC in 1993, and continually keeps an inventory of over $2 million of its range of Airlocks, Diverters and Slide Gate Valves and can ship any standard product within 24 hours from order placement.

More recently owing to the increasing global demands of our products, Rotolok has invested in over 500,000 square feet of freehold accommodation Worldwide which now includes operations in Australia, Europe, India, Singapore, South Africa and the USA that houses administration, manufacturing and test facilities.
