Control valves solve corrosion problems

Amot 25000 Series solenoid-operated pneumatic control valves, of all stainless steel construction, have provided a rapid solution to vibration and corrosion problems for a manufacturer of diesel engine generator sets being used to power hydraulic power packs for controlling offshore wellhead control panels, sub-sea actuators and two hydraulic lifting winches. High vibration was previously being transmitted to the engine’s emergency shut-down instrument panel, generating premature tripping of the existing solenoid valves. Harsh offshore conditions were also causing excessive internal and external corrosion, and frequent product failure caused by the high discharge velocity of exhausting process air. The 25000 Series is an EExd flameproof control valve off all stainless steel construction, with an epoxy coating on the solenoid coil housing giving additional corrosion protection.
