HERZ CAST IRON GATE VALVE
Flanged cast iron gate valve for shut-off applications in HVAC and water distribution systems
The HERZ STRÖMAX-AGF Globe Valve (4218 Series) from HERZ Armaturen is a flanged shut-off and commissioning valve for heating and cooling systems. Made from cast iron (GJL 250) with a brass upper part and EPDM seals, it provides long-term reliability and tight sealing.
The non-rising spindle ensures compact design and easy operation in all mounting positions. Available in DN25–DN80, the valve operates up to PN16 and 110°C, making it ideal for large hydronic installations. Its epoxy coating (RAL5000) protects against corrosion and mechanical wear.
