Type 70 - T70 High Flow Air Pressure Regulator
The Bellofram Precision Controls Type 70 is a high-flow air pressure regulator designed for applications that require substantial pneumatic flow and accurate downstream pressure control. It delivers flow up to 80 SCFM and supports supply pressure up to 250 psig. An aspirator tube helps maintain downstream pressure as flow changes, while a balanced supply valve reduces sensitivity to inlet-pressure variation. The Type 70 is used for large-flow actuation, louvers, rollers and winders, calibration loops, machine control, medical ventilation, laboratory equipment, and other high-flow OEM and industrial pneumatic systems.
Features:
- High Flow Capacity – Up to 80 SCFM (2266 LPM)
- Responds Quickly to Minute Changes in Downstream Pressure
- Dampening Action of Aspirator Tube Maintains Downstream Pressure
- Honking & Buzzing Eliminated By Action of Integral Baffle and Aspirator Tube
- Stack-up Construction Can Be Disassembled & Serviced without Removal from Air Line
- Optional Versions Include: Non-Relieving, Corrosive Resistant Epoxy Finish, Tapped Vent, Mounting Brackets, Pressure Gauge, Low Bleed, Check Valve
- Large Flow Actuation
- High-flow Louvers
- Rollers and Winders
- High-flow Control Loops
