Diaphragm Sensing Pressure Reducing Valves P20D

The ADCA P20D is a series of direct acting, spring-loaded, diaphragm
sensing and balanced plug pressure reducing valves.
These regulators are designed for use with compressed air, water and
other gases and liquids compatible with the construction materials
and valve design.
They are suitable for pressure reducing applications at the point of
use in laundry and dyeing machines, food industries, sterilizers, etc.

Compact design.
Non-rising adjustment knob.
Balanced valve plug.
Completely machined from solid bar stock material.
Ultrasonically cleaned.
