â… ï¼ŽProduct Introduction
The explosion-proof solenoid valve is a special control component designed for flammable, explosive, and corrosive working environments. It integrates electromagnetic control and mechanical switching functions, realizing precise on-off control of fluids and gases while effectively preventing internal electrical components from igniting external flammable and explosive media, thus ensuring operational safety in hazardous areas. Widely used in petroleum, chemical, pharmaceutical, coal mining, oil and gas transportation, and other industries, this valve plays a crucial role in optimizing process control, improving production efficiency, and eliminating potential safety hazards. It is an indispensable core component in automated control systems of hazardous industrial sites.
Ⅱ．Product Features
-
Excellent Explosion-Proof Performance: Adopts advanced explosion-proof structure design and high-quality sealing materials, which can effectively isolate the electric spark generated by the internal coil from the external flammable and explosive environment, complying with international explosion-proof standards and ensuring safe operation in hazardous areas.
-
Wide Adaptability: Suitable for a variety of working conditions, capable of circulating flammable, explosive, and corrosive fluids and gases. The fluid temperature, pressure, and diameter ranges are comprehensive, meeting different process requirements of industrial sites.
-
Diverse Control Modes: Supports normally open, normally closed, and self-maintaining control modes, matching different automated control logic. The international standard voltage options are rich, compatible with most industrial power supply systems, facilitating system integration.
-
High Reliability & Durability: The valve body is made of stainless steel (304, 316, 316L) and cast steel, featuring strong corrosion resistance, high pressure resistance, and wear resistance. The coil operates at a stable temperature, ensuring a long service life of the product.
-
Flexible Installation & Zero Leakage: Multiple connection methods such as threaded, flange, welding, clamp, and union are available, adapting to different installation scenarios. The product achieves zero leakage, avoiding medium leakage and environmental pollution, and ensuring process stability.
