Hayward Thermoplastic Ball Check Valves
Since the introduction of PVC in the 1940's, thermoplastic valves have gained wide acceptance and tend to be the material of choice.
Benefits Include:
- Non-Toxic
- Corrosion Resistance
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
Plastic valves are not affected by normal environmental conditions, providing years of maintenance-free service.
Low Thermal Conductivity
Valves have a much lower thermal conductivity than metal valves. Thus, heat loss or gain is greatly reduced. Pipe insulation is rarely required.
Improved Flow Rates
Valves have a high flow coefficient and unlike metal valves they will not pit, rust or corrode. Their interior walls are molded with an ultra smooth finish that remains smooth throughout the valve's service life - resulting in consistent flow rates over time.
High Temperature
Process control products are capable of handling corrosive chemicals at elevated temperatures - up to 250?F - with glass fiber reinforced PPL.
