Controlled Repair started as a control valve repair service company in 1972. At that time we were one of the first independent valve service companies in the UK, two people strong with a combined 30 years experience with Masoneilan and Crosby.

We continue to provide a top quality control valve service plus we have added Safety, Relief, Ball Control, Butterfly Control, Shutdown valves and associated instrumentation to our portfolio with customer satisfaction and quality as our primary concerns.

Over our 34 years of operation we have built up considerable experience, covering many manufacturer’s products and equipment, but in particular, Fisher, Masoneilan, Valtek, AHock and ASCO Numatics. Our extensive technical library of these manufacturers covers several decades.


Controlled Repair (Instruments) Ltd is a family run business and has been going for over 35 years. We are the only Fisher Approved Service Provider for the South and South East region, covering Fisher Controls and Fisher Regulator products. CRI has dealt closely with Fisher for 35 years and is an Official Fisher Approved Service Centre. We have had this accreditation for over 10 years.

CRI were approached by Flowserve to be come an Approved Service Centre for Valtek products in the South and South East of the UK which we were happy to become. Working with Flowserve has helped us provide a higher quality service for not only our customers, but to help support Flowserve’s customers and their requirements.

We are the only approved Distributor and Repair Centre in the UK for A.Hock products, who own the rights to Honeywell industrial product range and their own control valve and associated products. In 1999 the Honeywell factory closed and the rights to the Series 2000 valves among others was sold to Flowserve. Up until 2008 Flowserve sold these valves under the Valtek 2000 model. At the beginning of 2008 this was taken over by A.Hock, they took over the following Honeywell models, Series 2000, 600, 800, 9000, 2003-13, V5066 etc.
