KF-AIV Threaded &Flanged Isolator Valves

For Testing or Isolation of Safety Relief Valves, Pressure Transmitters,Gauges & Control Valves Without Removal or Shutdown of System.

KF has combined their field proven Series B/BH threaded end ballvalves to create this high pressure Isolator Valve. Up to 5000 psi tobe exact. Utilizing a second Series B/BH ball valve for side valvecontrol of testing media. Available in 1" or 2" sizes andmay be trimmed with optionally availableStainless Steel Ball and Stemfor NACE conformance.

KFs Standard Series threaded end Isolator Valve offersdependable isolation performance at an economical price.The Standard KF-AIV seal-welded Body and SideValve virtually eliminates all atmosphericleaks thru the Body. Male x FemaleNPT threaded ends allow forquick installation.

When the safety relief valve is tested, the KF-AIV is locked inthe closed position enabling the test media to be connected tothe port below the safety relief valve. Pressure is then applied to

the safety relief valve through the test port until relieving setpressure is verified. After set pressure is verified test port islocked closed and the Isolator Valve is locked in open position.
