Type 582 is designed for maintaining constant outlet pressure while Type 586 is designed for maintaining constant inlet pressure. Suited for aggressive chemical processing applications, the PVC and CPVC valves have compact size, modular design and chemical-resistant plastic construction without exposed metal parts. A central housing nut eliminates re-torqueing, and injection-molded arrows indicate flow direction. Operational performance includes tightness resistant to temperature cycling with constant and low vibrating control behavior. The pressure-regulating valves are available in sizes from 0.375 to 2” (DN 10 to DN 50).
