Product Description

Ggg40 Ductile Iron Body Flange  Exhaust Valve  Air vent Valve PN16 ductile Cast Iron Automatic Double Orifice Air Release Valve  

Material: ductile iron (complying with DIN standards), ensuring durability and cost-effectiveness.
Dual-orifice Design: Features large and small orifices for hierarchical air release (rapid exhaust during system startup and  air release during normal operation).
Float-Operated Mechanism: Self-actuating via buoyancy, triggering valve opening/closing without external power.
DIN-standard Flange Connection: Compatible with European pipeline systems, ensuring easy installation and sealing.PN16 ductile Cast Iron Automatic Double Orifice Air Release Valve PN16 ductile Cast Iron Automatic Double Orifice Air Release Valve PN16 ductile Cast Iron Automatic Double Orifice Air Release Valve PN16 ductile Cast Iron Automatic Double Orifice Air Release Valve PN16 ductile Cast Iron Automatic Double Orifice Air Release Valve
