Some common symptoms of valves failure are leakages when closed and erratic operational behaviour. These indications if unattended can lead to performance loss and operational breakdown.

Internal corrosion/erosion, build-up of deposits, rusting stem threads, hardening of packing, damage to o-rings and seat materials are just some of the factors that can impair your flow control system.
