HERZ DUCTILE IRON GATE VALVE
The HERZ Ductile Iron Gate Valve is a PN25-rated isolation valve engineered for reliability in demanding industrial and HVAC installations. Constructed from ductile iron (EN-JL 1050), it offers superior strength and pressure resistance compared to standard grey cast iron models.
Fitted with stainless-steel seat rings, wedge trim, and packing hardware, it delivers exceptional corrosion resistance and long operating life. The valve’s graphite-asbestos-free seals ensure leak-tight performance even under elevated temperatures.
