It has greater pressure drop capabilities than all other VALTORC bronze body valves. The equal percent plug provides excellent control characteristics and is more tolerant of oversizing than linear or quick-opening plugs. The standard hardened 17-4 stainless trim provides long life and is recommended for all applications over 50 PSI. The CV-500’s control close-off and wear characteristics are particularly well-suited to industrial applications.
