Adjustable pressure control valve

Adjustable pressure control valve to use: 1, medium flow direction should be consistent with the direction arrow on valve body; 2, adjustable pressure control valve should be installed in the return pipe, pressure pipe on the valve to guide the other end is connected to the water supply pipe connecting pipe, it is recommended supply-side installation guide pressure pipe 1/2 "ball valve, in order to eliminate the start clogging; 3, in the water supply pipe connecting pipe should be installed before the filter to avoid poor water quality caused by the loss of autoregulation valve; 4, water supply and return pipes of the valve before the pressure gauge should be installed separately, easy to adjust the control pressure; 5, found that the system is too large or too small flow, possible cause is debris card pipeline component mounting resistance when the valve plug may be 1/2 "ball valve is closed for 3-5 minutes, then if it is lighter jam, it can automatically eliminate, as yet not eliminated, will have to open the check valve to eliminate obstruction; 6, the control pressure adjustment method: adjusting control valve rod counterclockwise, the pressure was observed.
