Dungs Make Pressure Regulating Valve

The dungs fri pressure regulator is recommended for industrial and commercial heating applications and is suitable for natural gas, propane, butane, air and other inert gases. Manufacturing facility.
stand-alone pressure regulator and gas filter with threaded flanges
with mounting kit, fri pressure regulator with gas filter directly mounts upstream of the dmv (dual multi valve); no piping required. When fri regulator is mounted downstream of the dmv (dual multi valve), the gas filter is mounted to dmv inlet.
Regulator output pressure monitored by direct mounting an a2 type pressure switch to fri. Additional ports to sense inlet and outlet pressure are also located on the threaded flanges.
Precise and sensitive regulation
lock-up regulator (the outlet pressure shall not rise more than 15% or 3 in. W.c, whichever is greater, above the setpoint).
Limiting orifice; approved as a ventless regulator by some authorities having jurisdiction. (review applicable codes for vent line requirements)
high flow rate
easy-to-mount
compact
light weight
