Valve Maintenance (NZ) 2017 Ltd was originally established in 2013 as a Valve Maintenance, Overhaul and Repair Company and has since expanded to include mechanical engineering services. We are experienced in the overhaul and servicing of all types of valves across a broad spectrum of industries such as Power Generation, Petroleum, Dairy, Timber and Pulp & Paper Processing. VMNZ are IANZ Accredited for testing and certifying relief and safety valves, and hydrostatic testing of all types of valves. Valve services can be undertaken in either of our workshops located in New Plymouth and Taupo, or we can also offer two mobile testing options that save the customer both money and non-productive downtime.

Option 1: Mobile test bench capable of testing valves up to 200 barG on nitrogen. Option 2: Fully self-contained custom-made mobile test workshop.
