Performance Curves for 2" Plastic Two Position Slide Valve,
Models 14935-0100 and 14935-0300
NOTE: Curves represent total loss of both halves of valve (double pass thru valve).
Winterizing For Freezing Climates:

CONNECTING SLIDE V ALVE
TO FILTER SYSTEM
NOTICE: Filter ports and valve ports are furnished with union connections,
matching the connections of the filter ports. DO NOT use pipe sealants on
union collar (nut).
Use care before assembly not to damage union sealing surfaces or O-Ring.
Install union O-Rings in groove; tighten union collar hand tight.
FOR SLIP FITTINGS: Use correct solvent/cement when fitting piping or adapters
to slide valve. The valve body is ABS plastic, thus any good quality ABS to PVC
solvent can be used, such as Weld-On #793 or #710. Use P-70 (purple) primer
on PVC components only. Allow a minimum of four hours drying time prior to
pressure testing or operation. If ABS adapters are glued into valve ports in lieu
of PVC fittings, use Weld-On Solvent #771, #1707 or #773.
To avoid serious personal injury or property damage, follow
cement manufacturer's instructions exactly.
FOR THREADED FITTINGS: Use Plasto-Joint Stik
may degrade plastic and create poor joints and leaks.
NOTICE: Do not overtighten.
