Explosion-proof Electric Globe Valve DN80 Price, Explosion-proof Grade CT6
Factors Affecting the Price of Explosion-proof Electric Globe Valve DN80
Currently, the price of an explosion-proof electric globe valve DN80 with grade CT6 generally ranges from RMB 4,800 to RMB 12,000. The specific price is influenced by the following factors:
Valve Body Material: Cast steel (WCB) costs approximately RMB 4,800-7,500; stainless steel (304/316) costs RMB 7,000-12,000.
Explosion-proof Grade: CT6 is higher than BT4 and is suitable for IIC gas environments (hydrogen, acetylene, etc.). It is 20%-30% more expensive than BT4.
Electric Actuator Configuration: Standard on/off type costs RMB 4,800-6,500; modulating type (4-20mA signal control) requires a positioner, costing RMB 6,500-9,000; intelligent type with fail-safe function costs RMB 9,000-12,000.The main stop valve product names of China Stop Valve Network include:ANSI Flange Straight-through Bellows Globe Valve,High Temperature and Pressure Power Station Electric Globe Valve,Vacuum Isolated Straight-through Globe Valve,Y-type Jacket Insulation Globe Valve,Forged Steel Straight-through Globe Valve,Flange Straight-through Low Temperature Globe Valve,Oxygen-specific Globe Valve,GB Bellows Globe Valve.
Protection Grade: IP68 outdoor type is 10%-15% higher than standard IP67.
Core Requirements of CT6 Explosion-proof Grade
CT6 is an extremely high gas explosion-proof grade under the GB/T 3836 standard. "C" indicates that the equipment is suitable for IIC gases (the most dangerous gases such as hydrogen and acetylene), and "T6" indicates that the maximum surface temperature does not exceed 85°C (significantly lower than T4's 135°C). This grade ensures that the valve can operate safely in extremely hazardous environments without becoming an ignition source.
Purchasing Suggestions
It is recommended that users request the supplier to provide the explosion-proof certificate and CCC certification, confirming that both the actuator and the valve body are integrally designed for explosion protection rather than assembled from non-rated components. When purchasing, provide the medium type, pressure rating (Class 150/300 or PN16/40), opening/closing frequency, and control mode (on/off or modulating). It is advisable to choose a professional manufacturer with explosion-proof production qualifications and request quotes from at least three suppliers for comparison.
