Wilkerson WRA102 Series High Precision Regulator

BRAND : Wilkerson

Features

Control sensitivity of .125" (.32 cm) water column allows use in precision processes.
Pressure balanced supply valve prevents supply pressure changes from affecting the setpoint.
Optional check valve permits dumping of downstream pressure when supply is opened to atmosphere.
Separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.
An aspirator tube compensates downstream pressure droop under flow conditions.
