Product Overview
The BS5163 Metallic Seat Gate Valve PN16 NRS (Model 1110) is a high-performance ductile iron gate valve engineered to British Standard BS 5163 for waterworks applications. With a gunmetal/metallic seat ring configuration and non-rising stem (NRS) design, this valve delivers exceptional sealing performance, compact installation footprint, and energy-efficient operation across municipal water networks, industrial fluid systems, and irrigation infrastructure. Manufactured by Shandong Huaze Valve Co., Ltd. — a specialized valve producer with over 25 years of experience since 1998 — every valve is tested to EN 1074-1/-2 standards for guaranteed reliability.
The NRS (Non-Rising Stem) configuration means the stem does not extend upward during operation — the gate travels along the threaded stem internally. This makes the valve ideal for installations with vertical space constraints, such as buried valve chambers, basements, and compact pump rooms. With sizes ranging from DN50 up to DN800, the Model 1110 covers the full spectrum from small-bore branch isolation to large-diameter trunk main duty.
The metallic seat design — featuring a machined gunmetal (bronze) seat ring integrally cast into the body and a corresponding gunmetal facing on the wedge — provides excellent resistance to wire-drawing erosion, maintains sealing integrity under high differential pressure, and eliminates the temperature limitations of elastomeric seats. This makes the metallic seat gate valve particularly well-suited for high-cycle operation and applications where long-term seat durability is critical.
Key Features
BS 5163 Compliance — Built for Waterworks
Fully designed and manufactured to BS 5163 — the definitive British Standard for resilient-seated and metallic-seated gate valves for water supply. Face-to-face dimensions, flange drilling, material specifications, and test procedures all conform to the standard, ensuring seamless interchangeability with existing BS 5163 installations across the UK, Commonwealth, Middle East, and Southeast Asian markets.
Gunmetal Metallic Seat — Proven Durability
The body seat ring and wedge face are machined from high-grade gunmetal (bronze alloy), delivering a smooth, corrosion-resistant sealing surface that withstands repeated operation without degradation. Unlike soft-seated valves, the metallic seat is immune to scoring from suspended solids, unaffected by chemical disinfectants, and maintains dimensional stability over decades of service — a proven design trusted in water utilities worldwide.
NRS Design — Compact & Protected
The Non-Rising Stem mechanism keeps the stem threads permanently inside the valve body, lubricated by the line fluid and protected from external contamination, dust, and corrosion. This means no exposed stem to clean or grease, no risk of thread damage during backfilling, and a significantly reduced installation height — making the valve the preferred choice for buried chambers, meter pits, and low-headroom plant rooms.
Energy-Saving Low-Torque Operation
Precision-machined stem threads paired with a bronze stem nut deliver smooth, low-friction operation with reduced handwheel torque. Less physical effort means faster operation by field crews, lower actuator sizing requirements for motorized installations, and reduced wear on drivetrain components — translating directly into lower operational and maintenance costs over the valve's service life.
Ductile Iron Body — Strength You Can Count On
GGG50 ductile iron (EN-GJS-500-7) body and bonnet deliver roughly double the tensile strength of gray cast iron with far superior impact resistance. This makes the valve highly resistant to water hammer, ground settlement loads, transportation damage, and accidental impact during installation — critical for buried infrastructure where replacement costs far exceed the initial valve investment.
100% Fusion Bonded Epoxy Coating
Electrostatically applied and oven-cured FBE coating at minimum 250 um DFT on all internal and external surfaces. Spark-tested at 3 kV for complete pinhole-free coverage. This impermeable barrier protects the ductile iron substrate from corrosion in aggressive soils, treated water, and marine/coastal environments, ensuring a 30+ year service life even in the most demanding conditions.

Why Choose the Model 1110?
Metallic Seat = Long Service Life
The gunmetal-to-gunmetal sealing interface is immune to the aging, compression set, and chemical degradation that affect elastomeric seats. In water utility applications, metallic seat valves routinely achieve 50+ years of reliable service — a proven track record unmatched by any soft-seat design.
NRS = Lower Total Cost
No stem clearance means smaller valve chambers, less excavation, and reduced civil works costs. Internal stem threads stay permanently lubricated — eliminating the periodic maintenance that exposed rising stems require. Lower installation cost + lower maintenance cost = lower total cost of ownership.
BS 5163 = Proven Standard
BS 5163 has been the benchmark for waterworks gate valves since 1974. Specifying to this standard ensures compatibility with existing infrastructure, acceptance by water authorities, and compliance with the technical requirements familiar to consulting engineers across Commonwealth and Middle Eastern markets.
