MOI repairs and pressure tests all types of valves, including control valves, safety valves, ball valves and gate valves. Work can be carried out in the workshop, at site or offshore, and may include weld overlay, machining, reconditioning and reassembly.
Every valve is returned with documented test results so that operators can put it back into service with confidence. MOI also offers cryogenic valve testing and API-related valve services.
