Type F for domestic use

 Mod. F the two stage self-driven pressure regulators series f are widely used both in civil end industrial installations using natural gas, lpg or not corrosive gases. These regulators have been conceived to be directly installed on user’s flow meter or assembled on riser shafts for civil uses. They can be installed in any position provided that they are protected against atmospheric agents. The internal relief valve vent can be convoyed outside in case of installation with closed rooms or for underground plants. Thanks to the concept of double regulation stage, it is possible to achieve a: - high accuracy; - high operating reliability. Simple installation procedure. The regulator are manufactured according to uni 8827. Main features: - nominal flow rate 6 up to 50 stmc/h natural gas - inlet pressure range: bpu 0.15÷8.6 bar - bpu 2.2÷124.7 psi - max allowable pressure: ps 8.6 bar - ps 124.7 psi - outlet pressure range wd: bp: 13÷180 mbar - wd: 5.2÷72.3” wc tr: 180÷500 mbar - wd: 72.3÷201” wc - over pressure shut - off setting range: wd opso bp 35÷300 mbar - wd opso bp: 14÷120.5” wc wd opso tr 300÷800 mbar - wd opso tr: 120.5÷321.4” wc - accuracy class: ac 5/10/15/20% - lock up pressure class: sg 25% max - temperature class: 2 (-20°c +60°c) - (-4°f +140°f) - response time: lower than 3 sec.
