valve, relief device and integral off peak flow modulation. the system reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure. it protects the consumers from excessive pressure and ensures continues water supply in emergency...
is above set point, it connects port "c" to " ". ■ when sensed pressure is equal to set point, it blocks connections between all ports. ■ when sensed pressure is below set point, it connects port "c" with "a" and "z". an integral needle valve restricts flow through port "z". typical applications ■ pressure...
