5600 Series Control Valve

The 5600 series control valve has enjoyed years of continuous

service in the water treatment industry. It is one of the longest
running valve series on the market today. We use a metered
initiated regeneration so that your system regenerates only
when necessary with an accurately measured amount of sodi­um to conserve water and salt. The valve combines simplicity
and durability all in one.

Resin Tank

Features a non-corrosive fiberglass tank with a thermoplastic
inner liner. The tanks are approved by NSF, UL, DA, and meet
WQA standard S-100.

Brine Tank/Cabinet

The brine tank is a combination brine maker and salt storage
vessel that is made of tough corrosion free polyethylene and
comes with a safety float to guard against brine tank overflow
issues.
