Wanhe Testing Completes Upgrade of Water‑Gas Linkage Valve Testing Equipment, Enhancing Inspection Accuracy for Water Heater Components

In May 2026, Zhongshan Wanhe Testing Equipment Development Co., Ltd. completed the upgrade of its WH-RS01‑215 Water‑Gas Linkage Valve Testing Equipment. The upgraded system now serves as a comprehensive testing platform for key water heater components, capable of performing full performance and aging tests on burners, heat exchangers, water‑gas linkage valves, water flow sensors, and circulating pumps.

The technical enhancements include the integration of a gas‑driven automatic booster pump, enabling step‑wise pressure holding and stepless adjustment of output pressure, with a test pressure range of 0–3MPa. During testing, the system automatically compensates for pressure variations, ensuring stable test pressure and high measurement accuracy. Additional features include automatic data saving upon power failure, safe pressure‑relief protection, and automatic shutdown with alarm on completion or fault. All media‑contact parts are made of stainless steel for long service life. Even before the upgrade, the WH-RS01‑215 already offered multi‑stage water pressure testing (0.1MPa, 0.3MPa, 0.4MPa) for flow and start‑up water pressure detection, controlled via a touchscreen and PLC with independent start/stop switches for each test station. The new upgrade further refines pressure control precision and automation levels. This enhancement solidifies Wanhe Testing’s technological edge in water heater component inspection, offering manufacturers more accurate and reliable quality control solutions for their supply chain.
