installation guide
1Before installing the pressure reducing valve, the pipeline system must be flushed and cleaned to prevent welding slag and debris from flowing into the valve and affecting the normal operation of the valve;
2The pressure reducing valve should be installed in a place that is convenient for operation and maintenance (see the installation diagram). Pay attention to ensuring that the flow direction of the medium in the pipeline is consistent with the direction shown by the arrow on the valve body, and do not install it in reverse;
3When installing and using the pressure reducing valve, the stop valve of the bypass pipe should be opened to discharge the mixture of condensed water and steam water in the pipe to prevent water hammer from occurring when the pressure reducing valve is opened and damage the pressure reducing valve. Only when the phenomenon is no different can it be used normally;
4When the pressure reducing valve is shipped from the factory, the adjusting spring is in the self-state, and the valve flap is in the closed state. When in use, slowly turn the adjusting screw clockwise, compress the adjusting spring, and adjust the outlet pressure to the required pressure (based on the gauge pressure behind the valve). After adjustment, screw on the protective cover;
5A filter should be installed in front of the pressure reducing valve to prevent debris in the medium from entering the pressure reducing valve and affecting its performance. The filter must be inspected every 2 to 3 months and cleaned in a timely manner.
