Water Treatment and Injection

Water, whether a by-product of process separation or lifted direct from the sea, requires treatment before disposal or injection.


Produced water, SRU and water injection applications present challenging service conditions for installed equipment. Valves are specified to resist abrasive wear from suspended solids, or corrosion by saline water. PJ Valves’ proven designs and high-quality duplex materials make us a reliable partner for water treatment providers.
