Argus Pressure Isolation Valves - Ultimate Safety and Control

Argus pressure isolation valves allow you to calibrate your safety equipment or perform maintenance without shutting in the line. When the isolation valve is open, you have pressure gauge indication and process control. When closed, you can safely and easily calibrate your Argus pressure switch or pressure pilot. Then simply reopen the valve.

Specifications & Features of Argus Pressure Isolation Valves

The one-piece A350-LF2 body construction and NACE trim of Argus pressure isolation valves will handle the full spectrum of service conditions and temperature ranges. This smart design reduces the risk of freezing off and minimizes potential leak paths, while the self-adjusting stem packing means minimal maintenance. Safety is also enhanced through the blow-out proof and back-seated stem.
