DUCTILE IRON GLOBE VALVE MANUFACTURERS IN INDIA

Speciality Valve as one of the finest Ductile Iron Globe Valve Manufacturers in India, providing tough throttling valves designed for increased pressure ratings and enhanced impact resistance. Infrastructure applications demand valves that offer the cost advantages of cast iron along with the durability of steel.

Meaning: Ductile Iron Globe Valve

A ductile-iron globe valve has a body made of spheroidal-graphite iron (GJS-500-7) that provides greater tensile strength and elongation than grey iron. Globe-type internals ensure accurate modulation of flow, whereas the material’s ductility fights shock and pipeline stresses.

Why Required?

Municipal water distribution systems, desalination facilities, and industrial cooling loops frequently have pressures greater than PN 16 or experience pressure transients. Ductile iron resists these stresses, offers superior corrosion allowance, and maintains procurement costs below carbon steel—making it the smart utility engineer’s choice.

Key Components of Ductile Iron Globe Valve

· Body & Bonnet: ductile iron with fusion-bonded epoxy lining

· Disc: rubber-faced resilient plug

· Seat Ring: stainless or bronze, field-replaceable

· Stem: rolled-thread stainless steel for long life

· Packing: low-friction graphite or PTFE

· Handwheel/Gearbox: bevel-gear, manual, or electric actuator

Working

Handwheel rotation is converted to linear movement of stem. The modulating disc adjusts orifice size, regulating flow with small hysteresis. Strength of ductile-iron body resists surge pressures, while epoxy interior coating resists corrosion and scaling.

Advantages of Ductile Iron Globe Valve

· Increased pressure rating over grey-iron equivalents

· Long corrosion-free life by epoxy coating
