Advantages

Comprehensive Automatic Safety Protection

The Brass Gas Valve with Control Valve automatically shuts off the gas supply in case of abnormal pressure or excessive flow. Valve response time is ≤3 seconds, pressure sensing accuracy is ±0.005MPa, and closure is triggered by a minimum pressure change of 0.001MPa. Flow over-limit locking time is ≤0.5 seconds, ensuring the safety and reliability of gas networks in residential or commercial kitchens.

High-Precision Sensing and Customizable Thresholds

The valve employs a spring piston and negative pressure diaphragm sensing mechanism, allowing for precise setting of overpressure thresholds (adjustable from 0.1–0.3MPa) and long-term stability. The diaphragm deformation recovery rate is ≥99%, and the flow sensing accuracy is ±5%, meeting the safety requirements of various usage scenarios.

Durable and Long-Lasting

Key components are precision forged from brass, fluororubber/PTFE composite materials, and aerospace-grade aluminum alloy, with a hard anodized surface treatment. The spring fatigue life is ≥100,000 closure cycles, and it is corrosion-resistant and wear-resistant.
