Gas Emergency Shut off Solenoid Valves
The Gas Emergency Shut-Off Solenoid Valve is a safety-critical device designed to automatically cut gas flow during emergencies, vibrations, or earthquakes. Compatible with natural gas, LPG, and artificial gas, it operates via a DC 9V–12V electric pulse, manual red-knob trigger, or built-in vibration sensor. Built with a durable brass alloy body and NBR rubber seal, it closes in under 1 second and supports manual reset, making it ideal for residential, commercial, and industrial gas safety systems.
صمام الإغلاق الكهرومغناطيسي للغاز في حالات الطوارئ هو جهاز أمان مصمم لقطع تدفق الغاز تلقائياً عند الطوارئ أو الاهتزازات أو الزلازل. يدعم الغاز الطبيعي والغاز المسال والغاز الصناعي، ويعمل عبر نبضة كهربائية 9-12 فولت أو يدوياً عبر الزر الأحمر أو حساس الاهتزاز المدمج. مصنوع من سبيكة نحاسية متينة مع مانع تسرب NBR، يُغلق في أقل من ثانية ويدعم إعادة التشغيل اليدوي، مثالي لأنظمة سلامة الغاز السكنية والتجارية والصناعية.
The Gas Emergency Shut-Off Solenoid Valve is a professional-grade safety component engineered to instantly stop gas flow under hazardous conditions. It provides three independent shut-off methods — an electrical pulse signal, a manual push-button (red knob), and an automatic mechanical trigger that activates when strong vibrations are detected (such as earthquakes or impacts). This multi-layered protection makes the valve a critical element in any modern gas safety system.
The valve is constructed from a robust brass alloy body with a NBR rubber seal, ensuring excellent corrosion resistance, long service life, and reliable sealing across a wide range of gas types including natural gas, LPG (liquefied petroleum gas), artificial gas, and other non-corrosive gases. It closes in less than one second upon receiving a DC 9V–12V pulse signal, making it suitable for integration with gas leak detectors, smart home safety controllers, and centralized building management systems.
After activation, the valve remains in the closed position until manually reset by pulling the red knob upward — but only after pressure on the inlet and outlet sides has been equalized, ensuring safe and controlled re-opening. The encapsulated explosion-proof design adds an extra layer of protection in demanding environments.
Important: This valve must be installed only by a qualified contractor, downstream of the indoor main gas valve, with the flow direction arrow strictly observed and correct wiring polarity (white = positive, black = negative).
