We can also supply water level cocks, water level gauges for low and high pressure along with pressure gauge repair, re-calibration, and replacement. Our services can be carried out on or off-site, and our expertise in valve overhaul and industrial valve repair will help you to keep your industrial boiler running efficiently and safely as possible for many years.

Our comprehensive and thorough service includes everything from start to finish, from the on-site removal of the valves and cleaning of the boiler or vessel flange, the full examination and machining of parts right down to the pressure testing (pressure test certificate provided) and reports for future requirements.

Our initial assessment will include diagnostics or testing as required plus a full strip down, inspection and reassembly of all components. Where it is necessary to replace any parts, this will be done at the time, and the valve will then be fully tested to ensure correct and efficient working order.

Every part of the process is carried out in strict accordance to all relevant regulations and accreditations.

With our extensive expertise in valve overhaul and industrial valve repair plus in-house stock of spare parts, we can manage the entire process from beginning to end and at a very competitive price.
