Benefits of Plastic Valves and Flow Control Products
Since the introduction of PVC in the U.S. during the 1940's, thermoplastic valves,
pipe and fittings have gained wide acceptance. They are often the material of choice
for systems that were traditionally designed in metal. Unlike metal, however, plastic
valves and components have a high resistance to corrosion, will not scale or rust,
and will not contaminate sensitive fluids. Further, as non-conductors, they are
immune to electrolytic and galvanic corrosion. Equally important, they contain nothing
to leach out and contaminate sensitive fluids.
Non-Toxic
Hayward PVC and CPVC products are suitable for use with potable water and are consistent
with the National Sanitation Foundation and Canadian Standards Association standards.
Corrosion Resistance
Hayward plastic valves and flow control products are immune to corrosion. They are
dielectric - meaning they will not support a charge and will remain free from the
ionization and corrosion that occurs with metal valves.
Extended Service Life
Hayward plastic valves will outlast most metal valves, and are not affected by normal
weather conditions. They will provide years of maintenance-free service.
Low Thermal Conductivity
Hayward plastic valves have a high flow coefficient and, as compared to metal, will
absolutely not pit, rust or corrode. Their interior walls are molded with an ultra-smooth
finish that will remain smooth throughout the valves' service lives - resulting
in more consistent flow rates over time.
High Temperature
Hayward process control products are capable of handling corrosive chemicals at
elevated temperatures - up to 250°F with glass-fiber-reinforced PPL.
Easy Installation
Hayward plastic valves and flow control products are generally 1/3 to 1/2 the weight
of similar size and type metal valves. They are easy to install and result in reduced
handling, labor, freight, and installation costs.
Conservation
Hayward plastic valves are energy efficient. It takes about half the energy to produce
a Hayward plastic valve as a comparably-sized metal one.
Economics
When evaluating the economies of Hayward plastic valves over metal valves, consider
not only the initial cost savings of the product, but the reduced freight, lower
installation and maintenance costs and the extended service life of the valves.
