Clack WS 1 User Manual

Clack WS 1 water softener valve – parts and operational manual
Bypass Valve
The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure
in order to perform control valve repairs or maintenance. The WS 1 bypass valve is particularly unique in
the water treatment industry due to its versatility and state of the art design features. The 1″ full flow
bypass valve incorporates four positions including a diagnostic position that allows service personal to
work on a pressurized system while still providing untreated bypass water to the facility or residence.
It’s completely non-metallic, all plastic design allows for easy access and serviceability without the need
for tools.
The bypass body and rotors are glass filled Noryl and the nuts and caps are glass filled polypropylene. All
seals are self-lubricating EPDM to help prevent valve seizing after long periods of non-use. Internal 0-
rings can easily be replaced if service is required.
The bypass consists of two interchangeable plug valves that are operated independently by red arrow
shaped handles. The handles identity the flow direction of the water. The plug valves enable the bypass
valve to operate in four positions.
Normal Operation Position: The inlet and outlet handles point in the direction of flow indicated by the
engraved arrows on the control valve. Water flows through the control valve during normal operation
and this position also allows the control valve to isolate the media bed during the regeneration cycle.
