BYPASS VALVE
The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure in order to per-form
control valve repairs or maintenance. The W100SM 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 personnel 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 nonuse .Internal o-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 identify 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. (See figure 17)
Bypass Position: The inlet and outlet handles point to the center of the bypass, the control valve is isolated from the water
pressure contained in the plumbing system. Untreated water is supplied to the plumbing system. (See figure 18)
Diagnostic Position: The inlet handle points in the direction of flow and the outlet handle points to the center of bypass
valve, system water pressure is allowed to the control valve and the plumbing system while not allowing water to exit from
the exiting current constant and moving a permanent magnet near the semiconductor produces a voltage output proportional
to the movement of the magnet. Hall-effect devices provide a high-speed response, excellent temperature stability and no
physical contact.** Has not been tested for compliance with California Proposition 65 so this control valve to the plumbing.
(See figure 19)
Shut-Off Position: The inlet handle points to the center off the bypass valve and the outlet handle points in the direction of
flow; the water is shut off to the plumbing systems. If water is available on the outlet side of the softener it is an indication of
water bypass around the system (i.e. a plumbing connection somewhere in the building bypasses the system). (See figure
