Available in CPVC and PVDF materials for higher-temperature or high-purity applications, NVA Series has integrated stem with PTFE seat. Sizes range from ¼–½ in., and FPM seals are standard. While all valves carry 150 psi rating (non-shock at 70°F), respective max service temperatures are 190 and 280°F for CPVC and PVDF valves. Suited for fine regulation of flow required in instrumentation and laboratory work, valves also feature fine pitch stem threads for precise adjustment.
