Product Overview
The Safe Gate Valve Ductile Iron Industrial Gate Valve DIN Standard (Model 1002) is a DIN 3352 compliant, ductile iron gate valve designed and manufactured by Shandong Huaze Valve Co., Ltd. — an ISO 9001 certified manufacturer with over 25 years of specialized valve production. Constructed from GGG50 ductile iron (EN-GJS-500-7) with stainless steel stem, bronze stem nut, stainless steel fasteners, and 100% fusion bonded epoxy coating on all internal and external surfaces, the Model 1002 delivers reliable isolation performance for water, wastewater, fire protection, and general industrial fluid systems from DN40 to DN600. Every valve is individually hydrostatically tested to EN 1074-1/-2 at 24 bar shell and 18 bar seat.
The Model 1002 represents proven, no-surprises engineering: materials and design choices that have been validated across thousands of installations, backed by individual test certification, and supported by a manufacturer with a quarter-century track record. It is a valve you specify with confidence — whether for a single replacement, a new pumping station, or a multi-million-dollar water infrastructure project.
Key Features
GGG50 Ductile Iron Body & Bonnet
Ductile iron EN-GJS-500-7 provides 500 MPa tensile strength, 320 MPa yield, and minimum 7% elongation — approximately double the strength and seven times the ductility of gray cast iron (GG25). This material absorbs water hammer transients, pipe stress, and accidental impact through deformation rather than fracture, providing a fundamental safety margin that gray iron cannot offer.
Stainless Steel Stem & Fasteners
SS420/SS431 stem with precision-rolled trapezoidal threads and A2-70 stainless steel fasteners throughout — no carbon steel components in contact with the service environment. This ensures long-term operability and serviceability: the valve that is closed today will still open when needed in 15 years.
100% Fusion Bonded Epoxy Coating
Electrostatically applied, oven-cured FBE at minimum 250 um DFT on all internal and external surfaces. Every valve is individually spark-tested at 3 kV for pinhole detection. This thermosetting polymer barrier protects the ductile iron substrate from corrosion in buried service, treated water, and aggressive atmospheric conditions.
Bronze Stem Nut — Self-Lubricating Operation
The high-strength bronze stem nut provides inherently low-friction, self-lubricating performance without external grease. Combined with the roll-finished stainless steel stem threads, this ensures smooth, consistent handwheel torque over thousands of operating cycles.
100% Individual Testing — Every Valve Verified
Shell hydrostatic test at 24 bar (1.5x PN), seat tightness test at 18 bar (1.1x PN), FBE coating spark test at 3 kV, dimensional verification, and operational torque test — performed on every single valve. No statistical sampling. The valve you receive has been individually proven.
DIN Standard — Guaranteed Interchangeability
EN 558-1 face-to-face dimensions and EN 1092-2 PN10/PN16 dual-rated flange drilling ensure the Model 1002 fits directly into any DIN-standard installation — no adaptors, no modifications. Available from DN40 to DN600 across 15 standard sizes with identical specifications.
