Hayward Flow Control has expanded its NVA Series Needles Valves and now includes CPVC and PVDF materials. With these additional materials to the line, the NVA Series increases the range of applications and services where they can used, be it higher temperatures or hi-purity.
The NVA Series features an integrated stem with a PTFE seat for superior control, purity and performance. The valve sizes range from 1⁄4” (DN8) to 1⁄2” (DN10). FPM Seals are standard. All valves carry a pressure rating of 150psi / 10 bar Non-Shock at 70°F. Maximum service temperature for CPVC valves is 190°F / 88°C and for PVDF valves, 280°F / 138°C.
The NVA Series is a patent pending design with all thermoplastic construction that stands up to the most demanding of applications. They are ideally suited for the fine regulation of flow that is required in instrumentation and laboratory work. Typical applications or installations include, but are not limited to, water and wastewater treatment, chemical processing, pharmaceutical, hi-purity systems, food & beverage, aquatic and animal life support systems.
