WRA102 Series
STANDARD HIGH PRECISION REGULATOR
Flows to 40 SCFM
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.
