ARCUS Syphons are used to protect pressure gauges, transmitters, and switches from high-temperature steam or fluid. By allowing the process medium to cool before reaching the instrument, syphons prevent damage and improve accuracy and service life. Available in Pigtail, Q-Type, and U-Type configurations to suit various mounting and process needs.

Set Pressure Range | Factory preset or adjustable from 0 to 600 bar |
Connection Size | ¼”, ½” BSP/NPT (Male x Female / Male x Male) |
Accuracy | ±1% of set pressure (typical) |
Max Pressure Rating | Up to 700 bar (model-specific) |
Temperature Range | -20°C to +200°C |
Thread Standard | BSP / NPT |
Installation | Direct mounting between pressure gauge and process line |
ARCUS Gauge Cocks are shut-off valves used to isolate pressure gauges from the process line. They enable safe removal, inspection, or replacement of pressure instruments without interrupting the system. Designed for durability and ease of operation, Gauge Cocks are essential for protecting gauges and ensuring operator safety.
Type | 1-Way, 2-Way, and 3-Way |
Material | SS304, SS316, Brass, Forged Steel |
