Propane pressure regulator FHR 250

for compressed airfor gasheated gas

The precision pressure regulator FHR 250 serves the pressure reduction of air and neutral ases down to pressures within the mbar range. This is reached by a very thin diaphragm from strengthened synthetic rubber, as well as a Cantilever transmission for the actuation of the valve piston. The diaphragm housing can be rotated steplessly against the tubing ports. Thus a horizontal adjustment of the diaphragm is possible in all installation positions. An optionally installed blow-off valve is in the position to regulate excessive pressure on the outlet pressure side. The particular area of application of these pressure control valves are where high requirements are required in accuracy, stable regulation, as well as durable building quality. Through different valve seat diameters, as well as various adjusting springs, these pressure control valves can be individually adjusted to the requirements needed e.g. as tank ventilation regulators and burning and heating gas regulation.
