Tempress - Specific Performance and Safety Advantages

• The cartridge is injection molded NORYL plastic. Neither Time nor water quality (hardness, chemical treatment) affect the NORYL material.
• Back - to- Back installations are easily accomplished by rotating the cartridge 180 degrees, thus eliminating costly reversed piping.
• All moving parts are self-contained within the cartridge. Service is, but not limited to, simply exchanging a cartridge. The user now has a brand-new valve, not a repaired one.
• The EPDM rubber diaphragm allows for a greater surface impact of the hot or Cold water forces and will not bind or lock-up. This allows for higher control accuracy of the mixed water temperature, or, "Safety Mix".
• Sustained operating pressures as low as 20 psi is acceptable.
• The diaphragm is designed so that it will not blow out or puncture and has passed test pressures of up to 500 psi.
• The pressure balancing assembly is ultrasonically welded onto the diaphragm.
• The Tempress II and EF (Enhanced Flow) cartridge models meet or exceed a performance tolerance of + 2 degrees F controllability with pressure drops of 50%.
• Automatic flow shut-off in event of total pressure failure in either Hot or Cold supply.
• An escutcheon, which corrects any misalignment up to 7 � degrees between the valve and the wall surface. **
• Extension kits are available for either a 1/2" or 3/4" adjustment to the valve body rough-in.
• Full 270 degree Mixer rotation which opens and closes through Cold.

** Not available in all models.

TEMPRESS II EF

TEMPRESS II

NORYL Phenylene Oxide Based Resin

Developed by General Electric Corporation, phenylene oxide based resins carry Underwriters Laboratories (UL) continuous use temperature ratings from 50-100 degrees C. The resins offer good impact resistance even at -40 degrees F, have a very low water absorption rate and are completely resistant to hydrolysis. Boiling water, detergents, acidic or base solutions, create negligible dimensional change. The ability of NORYL resins to maintain specification even under constant strain conditions lends the material for use in moulded parts subject to prolonged or applied stress.

TEMPRESS II RPB VALVE

EPDM Ethylene-Propylene Elastomer

A tough-service elastomers material, EPDM has an extensive sealing life at high temperatures in Hot water; resistance to heat degradation; low compression set; low temperature flexibility; high abrasion resistance, and resistance to ozone and other severe atmospheric conditions. In all applicable services it has negligible compression set, distortion, hardness change or swelling through its temperature range of -65 to +350 degrees F.
