Pressure sustaining plastic valve with plastic pilot

Description

Hydraulic control valve used to maintain upstream pressure value constant. The valve opens when the inlet pressure reaches a preset level by means of a three way plastic reducing pilot incorporated. This valve controls the inlet pressure and maintains it constant without being affected from upstream flow and pressure variations.
When upstream pressure value is lower than the preset pressure value, the valve closes completely.

Applications

Upstream pressure control.
Pump system protection against excessive demand.
