Product Overview

The BS5163 Industrial Gate Valve is a high-performance, OS&Y (Outside Screw and Yoke) gate valve engineered for demanding water supply and industrial fluid control applications. Manufactured by Shandong Huaze Valve Co., Ltd. with over two decades of valve production expertise, this PN16-rated valve combines ductile iron construction with advanced fusion bonded epoxy coating technology to deliver exceptional durability and corrosion resistance in both underground and above-ground installations.

Designed in full compliance with BS5163 and EN1074 standards, the valve features a wide diameter range from DN50 to DN600, making it suitable for municipal water distribution networks, industrial process piping, fire protection systems, and irrigation projects. The OS&Y design provides clear visual indication of valve position — open or closed — enhancing operational safety and ease of maintenance.

Key Features

• Ductile Iron Body & Bonnet: Superior strength and impact resistance compared to traditional cast iron, ensuring long service life under high-pressure conditions up to PN16 (16 kg/cm²).
• 100% Fusion Bonded Epoxy Coating: Both internal and external surfaces receive a full fusion bonded epoxy (FBE) coating, providing outstanding corrosion protection and resistance to chemicals commonly found in water and neutral oil media. Minimum coating thickness meets international standards.
• OS&Y (Outside Screw and Yoke) Design: The rising stem with external thread mechanism allows operators to visually confirm valve status at a glance. The stem threads are isolated from the flow media, preventing corrosion and ensuring smooth operation over extended service cycles.
• Wide Diameter Range: Available from DN50 (2") to DN600 (24"), covering the full spectrum of municipal and industrial pipeline requirements. Custom sizes available upon request.
• Resilient Wedge Design: The fully encapsulated ductile iron wedge with EPDM/NBR rubber lining ensures zero-leakage sealing performance, meeting the stringent seat test pressure of 18 kg/cm².
• Flange Compatibility: Flange drilling conforms to EN1092 PN10 and PN16 standards, ensuring universal compatibility with standard European and international flange connections.
• Low Operating Torque: Precision-machined stem and internal components reduce operating effort, compatible with manual handwheel, gearbox, electric actuator, or pneumatic actuator operation.

Technical Specifications

Applications

This BS5163 gate valve is designed to perform reliably across a wide range of fluid control applications:

• Municipal Water Supply: Distribution mains, branch pipelines, and service connections in urban and rural water networks.
• Wastewater Treatment: Isolation and flow control in treatment plants, pumping stations, and sludge handling systems.
• Fire Protection Systems: Fire hydrant supply lines, sprinkler system isolation, and fire water storage tank outlets.
• Industrial Process Piping: Cooling water circuits, neutral oil transfer lines, and general industrial fluid isolation in factories and processing plants.
• Irrigation & Agriculture: Main line isolation for large-scale irrigation systems, reservoir outlet control, and canal gate applications.
• HVAC & Building Services: Chilled water and condenser water isolation in commercial building mechanical systems.

Quality Assurance & Compliance

Every valve undergoes rigorous testing in accordance with EN1074-1 and EN1074-2 standards before shipment:

• Shell Strength Test: 1.5× rated pressure (24 kg/cm²) — verifies structural integrity of body and bonnet
• Seat Leakage Test: 1.1× rated pressure (18 kg/cm²) — confirms zero-leakage sealing performance
• Coating Inspection: Holiday detection and thickness measurement ensure 100% coverage of fusion bonded epoxy
• Dimensional Check: Face-to-face dimensions and flange drilling verified against EN1092 and BS5163
• Operation Test: Full open-close cycle test confirms smooth operation and correct torque values

Shandong Huaze Valve Co., Ltd. is ISO certified and maintains a comprehensive quality management system covering raw material inspection, in-process quality control, and final product testing.
