This 5-valve configuration includes two isolate valves, two equalize valves, and one vent valve, enabling full transmitter calibration and testing without removing the instrument. The 5030 version is suited for high-pressure systems with its metal-to-metal hard seat, while the 5130 version uses soft tips for bubble-tight sealing, especially in gas applications. Designed for natural gas systems, it supports safe depressurization and simplified maintenance.
