Hayward Flow Control has expanded its NVA series needle valves to now include CPVC and PVDF materials, increasing the range of applications and services where the NVA series can be used, be it higher temperatures or high purity. The NVA series features an integrated stem with a PTFE seat for superior control, purity, and performance. Sizes range from 1/4” (DN8) to 1/2” (DN10). FPM seals are standard. All valves carry a pressure rating of 150 psi/10 bar non-shock at 70°F. Maximum service temperature for CPVC valves is 190°F (88°C) and 280°F (138°C) for PVDF valves.
