Pressure reducing & pressure sustaining flanged valve with plastic pilot

Description

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 plastic pilots.

If the upstream pressure remains below of the sustaining preset pressure, the valve closes completely.

Applications

Upstream pressure control and downstream pressure control.

Available Models
