Improving Pressure Reducing Valve Safety and Stability Through Standardized Testing
2026-04-22
Pressure reducing valves are essential fluid control components widely used in petrochemical, municipal water supply, heating, firefighting, and long‑distance pipelines. Their pressure regulation stability, sealing reliability, and durability directly affect safety, energy efficiency, and service life. With industrial systems upgrading, higher requirements are placed on valve performance verification and quality control. The release of GB/T 12245‑2025 Methods of performance test for pressure reducing valves establishes a unified, standardized, and operable testing system, marking a new stage in the standardized development of pressure reducing valves in China.
As a drafting participant, Gaote Holding Group Co., Ltd. contributed to the formulation and verification of technical indicators, combining years of R&D and engineering experience in valve manufacturing. The company’s product range includes pressure reducing valves, butterfly valves, gate valves, and control valves, supported by mature technical and quality management systems in design, materials, sealing, and performance testing.
GB/T 12245‑2025 replaces the 2006 version, improving test systems, measuring conditions, items, and procedures. The standard specifies test device composition, pipeline layout, pressure tap specifications, and instrument precision, ensuring comparability and repeatability. It covers air, water, and steam, meeting different application scenarios.
The standard includes shell, sealing, pressure regulation, flow, flow characteristic, pressure characteristic, continuous operation, and outlet pressure static‑dynamic pressure rise tests. The new outlet pressure test addresses transient pressure changes, supporting overpressure protection assessment. Sealing tests provide multiple methods such as bubble counting for gas, liquid collection for water, and pressure rise testing, ensuring reliability. Continuous operation tests differentiate cycle times by sealing structure and diameter to expose weaknesses and verify long-term durability.
Instrument accuracy is improved, requiring pressure measurement within 0.5% of range, temperature resolution ±1°C, and flow instrument class ≥1.0, providing reliable data for design optimization, factory inspection, and certification.
Gaote Holding Group applies the standard to its R&D and production, with optimized flow channels and reliable sealing structures. Their valves pass strict tests, showing high regulation accuracy and stability. With a professional R&D team and full testing equipment, the company translates standardized requirements into product advantages.
GB/T 12245‑2025 promotes overall technical and product quality improvements. For manufacturers, it ensures standardized design and control; for users, it reduces operational risks; for testing institutions, it provides a unified benchmark. Standardization drives industrial upgrading by turning abstract requirements into measurable, repeatable procedures, supporting innovation and safe, efficient valve operation.
Future applications will move testing toward intelligent, digital, and integrated methods, combining standardized procedures with advanced sensing and data analysis to improve efficiency and accuracy, supporting lifecycle management and predictive maintenance. Standardized performance testing remains essential for ensuring quality and industry development.
