Product Overview
WJ-GP Gas Emergency Shut-off Valve is a high-efficiency and safe gas protection core equipment independently developed and manufactured by Zhejiang WEAJA. It belongs to the normally open type electromagnetic control shut-off device. It can be linked with combustible gas detectors and fire alarm systems, and can also be operated manually. In emergency situations such as gas leakage and pressure abnormalities, it quickly cuts off the gas supply to prevent the expansion of gas accidents such as explosions and poisoning from the source. It is an indispensable safety protection component in gas transmission and distribution systems. The product is compatible with various combustible gases such as natural gas and liquefied gas. It has a compact structure and convenient operation, taking into account both automatic and manual dual control modes. It is widely used in various gas usage scenarios such as households, catering, and industry, fully meeting the relevant safety requirements of the "Gas Engineering Project Specification" (GB55009-2021) and building a solid line of defense for gas safety.
Core Functions and Advantages
- Dual Control, Convenient for Emergencies: Equipped with an automatic and manual conversion clutch, supporting automatic linkage shut-off and manual emergency operation. In emergencies, there is no need to rely on power supply; manual operation can quickly cut off the gas source. It still ensures effective protection functions during power outages and network outages, achieving dual safety guarantees and handling various emergency scenarios more calmly.
- Strong Anti-interference and Stable Operation: Has excellent anti-radio interference performance, while insulation resistance >20MΩ and withstand voltage up to DC600V, effectively resisting electromagnetic interference, voltage fluctuations, and other external influences, avoiding false triggering or fault shutdown, ensuring long-term stable operation and reducing maintenance costs.
- Wide Adaptability and Complete Specifications: Covers multiple valve specifications such as 4-point, 6-point, 8-point, 1-inch, 1.25-inch, and 1.5-inch. The valve pressure reaches 1.6MPa, which can be adapted to gas pipelines of different calibers, meeting diversified installation needs in households, shops, small industrial sites, etc., with extremely strong versatility.
- Environmental Tolerance and Long-term Durability: Can work stably in a wide temperature range of -20℃~+85℃ and humidity <95%, suitable for complex working conditions such as high temperature and humidity. The structural design is solid and the material is excellent, not easy to damage during long-term use, and has a long service life.
- Energy Saving, Low Consumption, Safe and Reliable: Rated power is only 1.2W, working power range 0.24W~3.6W, extremely low energy consumption, no additional burden during long-term operation; Rated voltage DC12V, working voltage range DC8V~16V, strong voltage adaptability and safer operation.
Application Scenarios
WJ-GP Gas Emergency Shut-off Valve is compatible with various combustible gas pipelines such as natural gas and liquefied petroleum gas, and is widely used in the following scenarios to comprehensively ensure gas safety:
- Household Scenarios: Gas usage areas such as residential kitchens and balconies, paired with household gas detectors to achieve automatic gas leakage shut-off and protect home safety;
- Commercial Scenarios: Catering places such as restaurants, hotels, and canteens, as well as small commercial gas places such as convenience stores and gas stations, to meet the gas safety protection needs of densely populated scenarios;
- Industrial Scenarios: Small chemical workshops, gas boiler supporting, gas storage auxiliary areas, etc., suitable for safety protection in industrial light gas usage scenarios;
- Other Scenarios: Gas cylinder gas usage places (adapted to models with special cylinder valves), renovation of gas pipelines in old communities, gas safety supporting for new residential buildings, etc.
