The valve maintains a constant preset downstream pressure, without being affected from upstream flow and pressure variations. At the same time the valve sustains the upstream pressure at a preset minimum rate. To operate the valve uses two three way metal pilots.
Upstream pressure control and downstream pressure control.
Pump system protection against excessive demand.
1 ½”, 2”, 3” BSP (NPT optional)
