A 1-inch gas shut-off valve relies on optimized fluid dynamics and electromagnetic trigger response. Operating at millisecond speeds, our solenoids use precision-wound copper coils (Class H insulation, rated up to 180°C) that instantly generate the magnetic force required to release the valve's mechanical lock pin when triggered by an external controller.
In natural gas distribution and petrochemical processing, exposure to sour gas (containing hydrogen sulfide) and high humidity causes rapid galvanic corrosion. As an OEM manufacturer, we construct our valve bodies from cast aluminum alloy, hot-forged brass, or cast 316 stainless steel.
Modern facilities connect shut-off valves directly into integrated industrial safety networks. The 1-inch valve functions as the final control element in a Safety Instrumented Function (SIF). It accepts shutdown signals from gas controllers (such as the JB-TB-AT2020SE) to isolate fuel lines instantly.
Establishing reliable safety infrastructure requires balancing strict compliance with commercial feasibility. Our state-of-the-art Chinese manufacturing facilities offer unique cost structures, material sourcing advantages, and vertically integrated engineering teams. By combining domestic raw material supply chains with advanced CNC machining, we offer fast delivery times without compromising safety margins.
From rapid casting prototyping to specialized surface treatments, we control the entire process in-house. Our automated testing labs subject every 1-inch gas shut-off valve to high-pressure pneumatic tests, bubble leak detection, and solenoid response profiling before delivery. This thorough approach makes us the preferred OEM partner for gas safety equipment worldwide.

A 1-inch gas shut-off valve is an electro-mechanical safety device installed in fuel gas pipelines. When connected to control panels or leak detectors, it instantly cuts off the gas flow (usually in under 0.3 seconds) using a solenoid mechanism, preventing fires, explosions, or carbon monoxide accumulation.
Unlike standard motorized or manual valves, emergency solenoid valves feature a latching mechanism. They are designed to trip closed instantaneously when receiving an electrical pulse from a controller. They remain locked closed until manual intervention resets the valve, ensuring operations do not resume while a leak is still present.
For volatile, hazardous atmospheres, valves must have explosion-proof coils with Ex d or Ex mb certifications under ATEX, IECEx, or local standards. For high-reliability safety systems, look for valves with SIL 2 (Safety Integrity Level) certification.
Yes. As a manufacturer established in 2003, Xinhaosi provides complete OEM customization. This includes custom thread types (NPT, BSPT, G-threads), body materials (anodized aluminum, brass, stainless steel), custom coil voltages (12VDC, 24VDC, 110VAC, 220VAC), and custom co-branding packaging.
Manual reset is a fundamental safety standard (EN 161). It ensures that the pipeline system is manually inspected and repairs are completed before fuel gas flow is restored. This prevents gas from flowing back into rooms where appliances may have been left open.
Our high-performance 1-inch solenoid valves are designed for over 100,000 switching cycles and an operational lifespan of 10 to 15 years, depending on the environment, gas composition, and regular testing schedules.
