Specifications and Performance:
Spec.: 1 “$number”
Pressure level: lb~600 lb
Temperature: ~+427°c
Characteristics：
Three-way flow path design, one station installs two identical safety valve, one is on-line overpressure protection, while the other serves as maintenance spare. Low flow resistance ensures adequate discharge capacity of the safety valve. The operation of reversing system is safe, simple and fast. Rapid switching eliminates the need for device parking, provides continuous overpressure protection, and avoids costly cost losses from emergency parking repairs. Under each safety valve, a vent valve is installed to safely and effectively release the media before the safety valve is removed and into the discharge tube. The quick switching device is provided with a balance valve (high-pound ≥600lb) and thus operates lightly. The applicable temperature range is wide (low temperature to high temperature).
