What is an Instrument Root Valve?

An instrument root valve is used for isolation of pressure gauges,orifice plates, flush rings, and various measurement instruments. The instrument valve normally “lives” in the open position and is closed
only to isolate the instrument for service or replacement - thus the valve sees very few cycles over its life. The instrument root valve is made from wrought or cast material and is welded to prevent separation of the body and end, thus the valve is non-repairable and is replaced when required.The valve is available in ? and ? inch sizes, with male NPT by female NPT end connections common. Most IM valves are in higher pressure
applications (2000 - 5000 psi) and are rated at Class #2500. The stainless steel valve is API 607 Ed. 5 qualified. Multiple seat materials are available based on application - TFM (standard) Carbon filled PTFE,PEEK, and Ceramic). Materials of construction range from a base of 316L stainless, and extend based on application to include Monel,Hastelloy, and duplex stainless steels. PBM also provides a “double block and bleed” configuration.
