  • Product Info
  • Literature


The V5197A valve provides flow control of air, natural gas, liquid petroleum, & manufactured gases which require a high turn down ratio. The adjustment screw controls the maximum flow of gas, but keeps the linear modulating characteristics & stroke.


  • Used with air, natural, manufactured or liquefied petroleum (LP) gases.
  • For modulating applications that do not require final shutoff service of firing rate valve.
  • Two valve body types (small and large) applicable to seven pipe sizes: Small body type for 3/4 in. (19 mm), 1 in. (25 mm), 1-1/4 in. (32 mm), 1-1/2 in. (38 mm) and 2 in. (51 mm) pipes, NPT or ISO 7 threads. Large body type for 2 in. (51 mm), 2-1/2 in. (64 mm) and 3 in. (76 mm) pipes, NPT or ISO 7 threads.
  • Two downstream 1/4 in. NPT threaded pressure taps available.
  • Accepts C6097 Pressure Switch mounted directly to flange (downstream pressure tap only).
  • Unpainted cast aluminum body.
  • Suitable for electric or pneumatic operators with the appropriate linkage.
  • May be used with manufacturers own linkage and drive motor.
