Gaote Holding Group Leads Valve Industry Standardization with National Standards Drafting
2026-05-22
Gaote Holding Group Co., Ltd. has played a leading role as an official drafting unit in advancing the standardization of China’s fluid control industry. The company has participated in the formulation of multiple key national standards, including:
- GB/T 12232 2025 — Flanged Iron Gate Valves
- GB/T 12233 2025 — Casting Iron Globe Valves and Lift Check Valves
- GB/T 12245 2025 — Methods of Performance Test for Pressure Reducing Valves
- GB/T 21385 2025 — Metal Sealed Ball Valves
These standards replace previous versions and establish unified, standardized, and operable frameworks for valve design, manufacturing, inspection, and performance verification. They cover critical aspects such as structural design, material selection, sealing performance, safety requirements, and testing procedures, ensuring higher reliability, efficiency, and service life of valves used in municipal water supply, petrochemical, heating, firefighting, water treatment, and long-distance pipelines.
Key technical improvements include:
- Definition of rising and non-rising stem designs, wedge gates, and support structures.
- Optimized materials for wear resistance and smooth operation.
- Enhanced safety requirements, including lifting lugs, support bases, and operation indicators.
- Strict leakage and pressure test standards, including health-related requirements for drinking water.
- Comprehensive performance tests for flow, pressure regulation, continuous operation, and outlet pressure stability, covering transient conditions.
- Standardized instruments and procedures ensuring repeatability, comparability, and high accuracy.
Relying on decades of R&D, manufacturing, and engineering experience, Gaote provided numerous practical proposals and engineering cases incorporated into these standards. The company applies these standards to its full range of products, which include gate valves, globe valves, check valves, butterfly valves, pressure reducing valves, and control valves, supported by ISO three-system certification, SIL 3 functional safety certification, and national high-tech enterprise recognition.
Gaote’s products are recognized for reliable sealing, reasonable structure, operational stability, and long service life, widely applied in municipal engineering, water supply, petrochemical, and firefighting projects.
The adoption of these standards has not only unified design and production practices across the industry, but also reduced operational risks, improved system reliability, and provided a benchmark for testing institutions. Gaote Holding Group continues to uphold standards-led, quality-centered, innovation-driven principles, turning national standards into practical product advantages and contributing to the high-quality development of China’s valve industry. Future trends include intelligent, digital, and integrated testing and monitoring, supporting predictive maintenance and lifecycle management.
