Wilkerson WRA302 Series High Precision Regulator

BRAND : Wilkerson

Features

Control sensitivity of .250" (.63 cm) water column variation allows use in precision applications.
A compensating diaphragm lets the regulator remain unaffected by supply pressure changes.
Flow of up to 40 SCFM with 100 PSIG supply allows use in applications with high flow requirements.
An aspirator tube compensates downstream pressure droop under flow conditions.
A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.
Unit construction lets you service the Regulator without removing it from the line.
