Installing the Three-Way Valve
When threading any pipe into the ports of the three-way
valve, a backing wrench MUST be employed. You must
capture the valve body with a secondary wrench to avoid
damaging the internal seals. Valve bodies leaking from
improper installation are non-warrantable.
High Pressure Tab
Located between the valve body and the actuator mounting
bracket, is a yellow tab labeled “High Pressure” see Figure
17. This is for maintenance of the valve only.
If the valve stem begins leaking beneath the yellow tab
the internal packing material must be replaced. The “High
Pressure” tab is held on with two screws located under the
mounting bracket.
To replace the packing material, all water pressure must
be removed from the valve assembly and the assembly
must be isolated from the system water. Then remove the
actuator and bracket, then remove the two screws holding
the “High Pressure” tab in place.
At this point the packing material can be removed and
replaced just like any other valve assembly. The packing
material is not available from Raypak.
