Description
519 series Adjustable differential pressure by-pass valve
The adjustable differential pressure
by-pass valve ensures the head
pressure of the pump is proportional
to the number of two-way on/off,
modulating or thermostatic valves
being closed in the secondary
circuit, preventing pump overheating and excessive fluid velocity.
