Carbon Steel Spring Load Open Type Full Bore Safety Valve DN15-DN500 1.0-32.0 MPa Pressure Relief
Industrial-grade carbon steel safety valve with spring-loaded mechanism for pressure relief up to 32.0 MPa. Features full bore design, working temperature up to 300℃, and multiple material options including WCB, CF8, and CF8M. Provides reliable overpressure protection for chemical, oil & gas, and industrial applications with flange connections from DN15 to DN500.
This safety valve serves as a critical pressure reduction device designed to protect systems from overpressure conditions. It opens rapidly at predetermined pressure levels, gradually releasing excess pressure to prevent equipment damage, fire hazards, or explosions. The valve operates mechanically using system media, ensuring functionality during power outages when electronic safety devices may fail.
