Wilkerson WRA302 Series
Compact High Precision Regulators
The WRA302 Regulator is designed for applications that require high capacity and accurate process control in a small package. A poppet valve which is balanced by utilizing a
convoluted diaphragm, insures a constant output pressure even during wide supply pressure variations. Stability of regulated pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the air supply in accordance with the flow velocity.
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.
