In flammable and explosive environments such as petrochemical, chemical, and gas industries, pipeline pressure control requires not only precision and stability but also stringent explosion-proof performance of the equipment. The Explosion-Proof Electric Pressure Reducing Valve DN80, particularly with an explosion-proof level of CT6, has become an ideal choice for high-risk working conditions due to its excellent safety and control accuracy.The main pressure reducing valve product names of China Pressure Reducing Valve Network include:Proportional-Type Reducing Valve,Pilot-Type Oversized Diaphragm High Sensitivity Reducing Valve,Piston Adjustable Reducing And Stabilized Valve,Self-regulative ValveTunable Pressure-reducing-and-maintaining Valve

From a price perspective, the current market price for an electric pressure reducing valve DN80 with explosion-proof level CT6 typically ranges from 3,500 to 8,500 RMB per unit.Pressure relief valve Technology The specific price is influenced by several factors: first, the valve body material—cast steel or stainless steel is more expensive but offers stronger corrosion resistance; second, the brand of the electric actuator, with a significant price difference between domestic and imported brands; third, the explosion-proof certification level—CT6, as one of the highest gas explosion-proof levels (suitable for highly flammable gases such as hydrogen and acetylene), has manufacturing and testing costs far higher than those of ordinary explosion-proof products. For small to medium-sized projects, a single-unit purchase price between 4,500 and 6,000 RMB is common, while batch purchases or direct contact with manufacturers can bring some models down to around 3,800 RMB. Secondly, the explosion-proof level CT6 is critically important because it represents the equipment's safety capability in extremely hazardous environments. The CT6 rating means the valve's surface temperature does not exceed 85°C and it is fully applicable to environments containing hydrogen, acetylene, carbon disulfide, and other gases with very low ignition energy—scenarios that are especially critical in chemical reactors, natural gas pressure regulating stations, and gas station vapor recovery systems. This valve adopts a flameproof or intrinsically safe design, with an enclosure capable of withstanding internal explosions without damage and without igniting external explosive gases. In terms of performance, the Explosion-Proof Electric Pressure Reducing Valve DN80 precisely controls the valve core opening through an electric actuator, and with a PID adjustment module, achieves high-precision stable output of outlet pressure within ±1%. It also supports 4-20mA signal remote control, automatic pressure retention upon power failure, and overpressure protection, greatly enhancing system automation and safety. During installation, it is important to ensure that the explosion-proof cable entry device is well-sealed, properly grounded in strict accordance with the GB3836 standard, and installed on a horizontal section of pipeline with good ventilation and without strong vibration. In summary, although the Explosion-Proof Electric Pressure Reducing Valve DN80 (explosion-proof level CT6) has a higher unit cost than ordinary valves, its safety assurance capability in extremely hazardous environments is irreplaceable. About Pressure relief valveIt is recommended to verify the manufacturer's explosion-proof certificate and CNEX or NEPSI certification before purchase, prioritize brands with application cases in the petrochemical industry, and consult technical personnel for actuator torque and valve body material selection based on actual working pressure and flow requirements to achieve an optimal balance between safety and cost.
