Chemselect® Thermoplastic Valves are designed for trouble-free operation by utilizing Teflon rotors to eliminate the need for oiling or greasing the valve. Chemselect® Valves are manufactured from a variety of thermoplastics including:
PVC (Polyvinyl Chloride) PVC is often specified for its versatile characteristics. It has been used for over 30 years in chemical processing, plating, chilled water distribution, deionized water, chemical drainage, and many other applications. It has properties that lends itself to resisting chemical attacks by acids, alkalies, salt solutions, and a host of other chemicals. It is attacked by certain solvents, most chlorinated hydrocarbons and aromatics. Maximum temperature if 140°F. 125 PSI rated at 75°F water non-shock.
CPVC (Chlorinated Polyvinyl Chloride) CPVC has similar chemical resistance properties to that of PVC. It has a maximum temperature of 180°. 125 PSI rated at 75°F water non-shock.
PP (Polypropylene) PP is a member of the Polyolefin family. PP is not physically as strong as PVC or CPVC, however, it is chemically resistant to organic solvents as well as alkalies and acids. It does not hold up against strong oxidizing acids, chlorinated hydrocarbons, and aromatics. Ultraviolet radiation will degrade polyolefins over time. Maximum temperature is 180°F. 125 PSI rated at 75°F water non-shock.
PVDF (Polyvinylidene Fluoride) PVDF is tough, durable plastic with many unique properties. It has a very good resistance to most acids, bases, and organic solvents. Ultraviolet radiation does not significantly degrade material, however, the fluid in the system can be affected by U.V. Maximum temperature is 240°F. 125 PSI rated at 75°F water non-shock.
Teflon® Teflon® has superior resistance to most chemicals and solvents. It has self-lubricating properties and is a great choice in many applications. Maximum temperature is 400°F. 125 PSI rated at 75°F water non-shock.
