1. Product Overview
To further optimize the product portfolio of municipal and industrial fluid control solutions and meet diverse engineering working conditions at home and abroad, TianyiSuns launches the core Sluice Gate Valve series. Adopting mature casting technology and precision manufacturing standards, the product delivers stable, reliable performance with a focus on pipeline cut-off control. Featuring zero leakage, low pressure loss, superior corrosion resistance, and easy maintenance, our sluice gate valves provide high-quality and trustworthy valve solutions for municipal water supply and drainage, sewage treatment, industrial pipelines, and other fields.
2. Structural Design and Working Condition Adaptability
As a core cut-off valve for pipeline systems, the TianyiSuns sluice gate valve adopts a full-bore straight-through structure. The flexible lifting gate eliminates flow obstruction when fully open, effectively reducing pipeline head loss and lowering energy consumption of pump stations. Designed for stable long-term on-off control rather than flow regulation, it is highly suitable for reliable opening and closing of various pipeline systems. The product covers two mainstream structures: non-rising stem (NRS) and outside screw & yoke (OS&Y). It supports multiple driving modes including handwheel, gearbox, electric and pneumatic actuation, enabling flexible adaptation to above-ground installation and underground buried pipeline scenarios with strong universality and compatibility.
3. Core Performance and Quality Advantages
TianyiSuns consistently adheres to high-standard manufacturing principles in the performance and quality control of sluice gate valves. The valve body is made of high-strength ductile iron with excellent mechanical properties, impact resistance, and deformation resistance, and is well-suited to harsh outdoor and industrial working environments. Both internal and external surfaces are coated with fusion-bonded epoxy powder with standard thickness, providing outstanding anti-corrosion performance against sewage and humid conditions to extend the service life of equipment. The stainless steel valve stem features wear resistance, rust resistance, and low operating torque, ensuring flexible operation and stable long-term performance. Equipped with high-quality EPDM/NBR flexible sealing components, the valve achieves bidirectional bubble-tight shut-off, reaching Class A sealing standard, effectively solving common problems such as poor sealing and medium leakage of traditional gate valves and ensuring long-term safe and stable pipeline operation.
4. Specification Parameters and Quality Control
The sluice gate valve series covers a size range from DN40 to DN600 with pressure ratings of PN10, PN16 and PN25. Manufactured in strict accordance with international standards including DIN3202, BS5163 and AWWA C509, the product features high interchangeability and compatibility with mainstream global engineering supporting systems. Every valve undergoes 100% hydrostatic strength and tightness tests before delivery to ensure consistent and reliable quality. Customized OEM and ODM services are available to adjust dimensions, coatings, and actuator configurations according to customers' special working conditions.
5. Brand Strength and Product Value
Equipped with integrated production lines covering casting, machining, coating and testing, TianyiSuns specializes in the R&D and manufacturing of professional valve products. All valve series have obtained authoritative ISO and CE certifications. With stable product quality, standardized production systems and comprehensive service support, our products are exported to numerous countries and regions worldwide. The standardized and high-performance sluice gate valve series further improves the company's fluid control product layout and consolidates our core competitiveness in municipal engineering, environmental water treatment and industrial fluid industries.
6. Future Development Plan
In the future, TianyiSuns will continue to deepen its layout in the field of valves and pipeline accessories. Based on actual industry working condition demands, we will strictly adhere to precision manufacturing standards, continuously optimize product performance and process details. With reliable quality, professional technology, and customized services, we will provide more efficient, safer, and more economical integrated fluid system solutions for global customers.
