Peculiarity ：

1.4-kilogram version is available for flange connection following DN40-DN150.

2. Selection of outlet pressure spring: 10-50mbar 40-110mbar70-150mbar 150-230mbar

3. Outlet pressure grows for clockwise rotation; outlet pressure declines for anticlockwiserotation.

4. 4-kilogram inlet reducing valve is installed with feedback pipe with caliber at RP3/8; please install feedback pipe at the pipe diameter higher than 5 folds.

Installation instructions

To prevent pipeline overpressure, shall be installed in gas pressure reducing valve upstream and downstream overpressure automatic cut-of valve and safety relief pipe valves.

But if the pressure reducing valve downstream equipment than the pressure reducing valve pipe before the actual gas pressure high, the above two kinds of valves can be omitted.

Installing a pressure regulating valves, diaphragm should be level, level of pressure reducing valve is installed.

Must indicate the direction of air flow direction arrow on according to the pressure regulating valve installation,installation of pressure regulating valve inlet pipe and outlet pipe To the right tools.

Install pressure regulating valve not move when the casing.

If it is containing the filter pressure regulating valves, pressure regulating valve installed in the best place off the ground, easy to filter clean.

Best upstream of the pressure regulating valve configuration a corresponding filter.

Do not remove or block on the cover of the air vent, otherwise the valve cannot work normally.

Outlet pressure set by adjusting screw clockwise outlet pressure increases, the outlet pressure counterclockwise.

Pressure test hole, into the mouth and out of the mouth have a Rp1/4 "screw connection

Working temperature:15℃ ～+ 60℃
