Page 8: Operating Principle
3 – OPERATING PRINCIPLE The pressure regulator Domus HF works by principle of pressure loading in the diaphragm upper chamber. The pilot receives directly from the inlet pressure of the process and discharge in the diaphragm upper chamber the outlet pressure (set point) desirable to the process. -
Page 9: Pilot And Internal Filter
Installation and Operation Manual MI-23 Domus HF - Pressure Regulating Valve 3.1 –PILOT AND INTERNAL FILTER The series G31F and G33F pilot are simple diaphragm type. It is responsible for exact loading pressure for the pressure regulator open or close, under normal operating conditions, based on equilibrium existence between the regulating spring force and the outlet pressure of sensing line. -

1) The equipment are in perfect conditions or has evidences of damage during the transport, in case of perceptible damage in the equipment do not proceed with installations and get in contact with GASCAT. 2) The space provided for the acess and installation of equipment is appropriate, including future maintenance. -
Page 11: Filter
It is necessary to verify the flow direction before installing the regulator; this information could be found into marks in the equipment body. The pressure regulator model DOMUS HF is designed to work in the horizontal position with the actuator in the top position. -
Page 12: Sense Line
We do not recommend installations of any type of block valve in the sensing lines. The connections of DOMUS HF sense line is normally supplied for 10 mm OD pipe, however other connections could be arranged under consult. We recommend to not use pulse pick-up downstream of regulator with orifices with nominal diameter less than 3/8”. -
