Pilots
There are mainly used to command pilot operated regulator valves, whether they are Fail to Open (VD277), or Fail to Close (RG97, RG107 and RG2050 series). The pilots have a wide adjustable range depending of the output pressure to be controlled. Their set up is made by turning an adjustment screw only.
Recommended Use: They are mainly used with clean, non viscous gaseous fluids.
Mounting: in any position.
Accessories: Hand wheel for board mounting.
