FIELD: plumbing valves.
SUBSTANCE: invention relates to a plumbing valve with a water inlet, a water outlet, a membrane valve, which is located between the water inlet and outlet. Membrane valve includes: valve seat, balance port, pilot port and pilot spool. The control spool, by actuating when pressure is applied, is made with the possibility of being transferred to the first and second stable positions. The control spool in the first position closes the control hole, and in the second position it keeps it in a flowing state, and with an adjusting device, with the help of which, by means of a rotary movement, the flow through the plumbing valve is changed when the membrane valve is open.
EFFECT: invention is aimed at improving the possibility of changing the flow rate through a plumbing valve with an open membrane valve.
